Talmudology on the Parsha, Ha’azinu ~ Shabbat Shuva and Pandemic Behavior

As we speed towards Yom Kippur, we encounter the poetic parsha of Ha’azinu. It is a fire and brimstone poem, in which God threatens his people with all kinds of misfortunes because they abandoned his teachings:

דברים 32:15

וַיִּשְׁמַ֤ן יְשֻׁרוּן֙ וַיִּבְעָ֔ט שָׁמַ֖נְתָּ עָבִ֣יתָ כָּשִׂ֑יתָ וַיִּטֹּשׁ֙ אֱל֣וֹהַּ עָשָׂ֔הוּ וַיְנַבֵּ֖ל צ֥וּר יְשֻׁעָתֽוֹ׃        

So Jeshurun [i.e. Israel] grew fat and kicked—
You grew fat and gross and coarse—
They forsook the God who made them
And spurned the Rock of their support.

It is within this context that we read the verse on which we will focus our attention:

32:25 דברים

מִחוּץ֙ תְּשַׁכֶּל־חֶ֔רֶב וּמֵחֲדָרִ֖ים אֵימָ֑ה גַּם־בָּחוּר֙ גַּם־בְּתוּלָ֔ה יוֹנֵ֖ק עִם־אִ֥ישׁ שֵׂיבָֽה׃        

The sword shall deal death without,
As shall the terror within,
To youth and maiden alike,
The suckling as well as the aged.

The rabbis of the Talmud used this verse as a proof text for al ruling about behavior during a pandemic:

בבא קמא ס,ב

תָּנוּ רַבָּנַן: דֶּבֶר בָּעִיר – כַּנֵּס רַגְלֶיךָ, שֶׁנֶּאֱמַר: ״וְאַתֶּם לֹא תֵצְאוּ אִישׁ מִפֶּתַח בֵּיתוֹ עַד בֹּקֶר״. וְאוֹמֵר: ״לֵךְ עַמִּי בֹּא בַחֲדָרֶיךָ, וּסְגוֹר דְּלָתְךָ בַּעֲדֶךָ״. וְאוֹמֵר: ״מִחוּץ תְּשַׁכֶּל חֶרֶב, וּמֵחֲדָרִים אֵימָה״.

The Sages taught: If there is plague in the city, gather your feet, [i.e., limit the time you spend out of the house,] as it is stated in the verse: “And none of you shall go out of the opening of his house until the morning” (Exodus 12:22). And it says in another verse: “Come, my people, enter into your chambers, and shut your doors behind you; hide yourself for a little moment, until the anger has passed by” (Isaiah 26:20). And it says: “Outside the sword will bereave, and in the chambers terror” (Deuteronomy 32:25).

STAY Home

The Talmud has brought three proof-texts that support the advice to stay indoors during a pandemic. In the opening words of this important passage, the Talmud reverses what came to be the standard medical practice of isolating the sick. Instead, it isolated the healthy. Of course, the effect is the same: there is no contact between those who are ill and those who are well, but since there are usually many more healthy people than there are sick, the effort and social disruption of isolation of the former will be much greater.This talmudic intervention is also one that is now all too familiar to us from the widespread lockdowns and stay-at-home orders that began in 2020 during the COVID- 19 pandemic.

…Or don’t stay home

The talmudic advice to stay at home during an epidemic outbreak was ignored by later commentators and those who wrote the halakhic codes of Jewish law. commentators on the Talmud added their own rulings about social isolation during a pandemic. The Polish exegete Rabbi Shmuel Eidels known by his acronym as Maharsha (1555– 1631) wrote that the rabbis of the Talmud could not have been suggesting that one should not flee from the locus of a pandemic.

This is certainly not the case, because if there is an outbreak of plague in a town it is best to leave and flee for one’s life. Rather, the intent of the Talmud is that if one cannot flee, then do not go outside into the streets.

The Maharsha’s ruling was precicely the opposite of that in Bava Kamma.

In true talmudic fashion, this comment of the Maharsha was itself commented on by a later rabbi, Yosef Hayyim from Baghdad (1835– 1909) who is better known by the title of his major work on Jewish law, Ben Ish Hai. In his commentary on the Talmud, he wrote that

the words of the Maharsha are only applicable to [bubonic] plague. But in the case of cholera, even when arrangements could be made to care for a sick person at home, it is best to flee the city. Because cholera also frightens a person, and he can be consumed by the illness on account of this fear . . . Therefore it is best to flee far away so that his ears cannot hear and his eyes cannot see the sickness that rules over everyone, lest he be overtaken with fear, and he himself be taken, God forbid.

Several other medieval commentators ruled like Maharsha. They include Rabbi Ya’akov ben Moshe Moellin (c. 1365– 1427) who is better known by his acronym Maharil; the Polish Rabbi Shlomo Luria (1510–1573), better known as Maharshal, (who descended from a family line that it was claimed could be traced back to Rashi, and whose mother was herself a Talmudist of some repute); The Sefer Hasidim (The Book of the Pious), a collection of folk stories, customs, and ethical adjurations that originated in the German Jewish community around Regensberg in the thirteenth century; and the Polish Rabbi Moshe Isserles (1530– 1572), known as Rema. Without doubt the work of his that had the greatest influence on Ashkenazi Jewry was his gloss on the Shulhan Arukh, which had been written by a Sephardic Jew, Joseph Caro (d. 1575). Isserles’ gloss is the authoritative reference work for Ashkenazi Jews. Less well known is the fact that as a young man, the Rema Isserles had himself fled from a plague. Here is his description of what had happened.

I Moshe, (son of my father the honorable benefactor and leader Israel, may he live long) called Isserles from Krakow, was exiled having left our city in [5]‌ 316 [= 1556] because of the polluted air (may it not befall us). We were sojourners in a land that was not ours in the city of Shidlov which has neither figs nor vines and there is barely any water to drink. . . we could not celebrate [the minor festival of] Purim with the usual joy and happiness. In order to remove the sadness and dejection I resolved to stand and take pride in my creativity, for my wisdom helped me . . . and so I decided to investigate and expound on the meaning of the Megillah [The Book of Esther].

Minghag becomes normative law

In what he described as a self- imposed exile, Isserles wrote a book called Mehir Yayyin [The Cost of Wine] which was published some three years later in 1559.This experience surely played a part when he wrote a legal commentary called Darkhei Moshe [The Paths of Moses]. He cited Maharil, of course, but then quoted a rather unexpected source. It was from the Zohar, the central mystical text of the kabbalah, which had been printed for the very first time in 1558, the year before Isserles fled from the epidemic in Krakow.

. . . It is likewise written in Zohar, Parashat Vayera Elav, that one should flee the city. And even though the Talmud states, “If there is plague in the city, gather your feet” [i.e., limit the time you spend out of the house,] it seems to me that fleeing is certainly better, but if one can go inside and not leave [he need not flee]. If this is not possible, he is required to flee. And the custom of Israel is Torah [i.e., this custom is now normative law].

Martin Luther and Muslim Law on Fleeing

To put the writings of Moshe Isserles, Maharil and Maharshah into context, we should pause to consider the work of the German priest Martin Luther (1483–1546). It is of course well known that Luther was, even by the standard of his own day, virulently anti- Semitic. However, his thoughts on fleeing from a pandemic allow a comparison across very two religious traditions.

In the summer of 1527, bubonic plague struck northern Germany and despite an order to leave, Luther stayed to minister to the sick. He then published a pamphlet titled On Whether One Has To Flee Death [Ob man fur dem sterben fliehen muge], which proved to be very popular; it was published in four separate editions in 1527 alone, and there were a further eleven editions over the next several decades. Luther adopted a position that was quite different from the Jewish responsa of the time, for he wrote that not all who flee from a pandemic acted correctly. Only some had. The decision depended both on who the person was and the degree of faith they possessed. “Christ does not want his weak ones to be abandoned,” he wrote, citing the New Testament.Luther made it clear that it was forbidden to flee if the goal was disobedience to God’s word or command. But if the motive was to avoid infection, some leaders might be able to flee if others remained to minister and to keep social order. Otherwise, abandoning the local community [Gemeinda] was a great sin. Luther cited the biblical story of Abraham “who feared death and escaped it [furcht er den Tod und floch yhn] through pretending Sarah was his sister.

Muslims, or at least Ottoman Muslims, also adopted a theological stand in which fleeing from a plague was acceptable. It is still a point of academic debate as to how much Muslim law permitted these actions. But regardless of the finer points of Muslim law, during the 1604 outbreak of plague in Constantinople, the Muftis fled, like everyone else.

Why Bother to flee?

What lay at the core of these rulings, which ever way they went, was the belief that pandemics are a divine response to human sin. If falling ill was a punishment, then what sense did it make to flee, as if by doing so, God could no-longer find you and strike you with bubonic plague or diphtheria?

This is also the central message of the Book of Jonah that we read in the afternoon of Yom Kippur. There is no escaping God’s presence, and no escaping his justice. On this Shabbat Shuva, what better message could there be?

Chullin 134b ~ The Right. Always to the Right

חולין קלד, ב

ת"ר (דברים יח, ג) הזרוע זה זרוע ימין אתה אומר זה זרוע ימין או אינו אלא זרוע שמאל ת"ל הזרוע

The rabbis taught in a baraita: The verse states with regard to the gifts of the priesthood: “That they shall give to the priest the foreleg…” (Deuteronomy 18:3)…is this the right foreleg, or is it only the left foreleg? The verse states: “The foreleg.” The definite article indicates that the verse is referring to the right foreleg.

מאי תלמודא? כדאמר רבאהירך’ - המיומנת שבירך. הכא נמי הזרוע - המיומן שבזרוע

But how is it understood from the definite article that the verse is referring to the right foreleg? It is derived like that which Rava said with regard to the verse: [“Therefore the children of Israel do not eat the sciatic nerve which is upon the hollow of the thigh”(Genesis 32:33). The definite article indicates that this is referring to the most important thigh. Here too, the definite article in the term “the foreleg” indicates that the verse is referring to the most important foreleg, i.e., the right foreleg.

But why did the rabbis derive that “the most important” thigh is the right one? Why not the left one?

Let’s take a trip into the worlds of comparative religion, chirality, astronomy, and neuroscience to find out.

The importance of the right side in Judaism

In the Talmud and in normative Jewish practice, the preference to favor the right over the left is everywhere. Here are just a few. (How many more can you think of?)

  • When walking up the ramp to the top of the Altar in the Temple, the Cohen must make a right turn at the top. Following that, every turn he makes must be a right turn. (זבחים נד,ב)

  • Actually, the entire service in the Temple in Jerusalem must be performed with the right hand. (ביאת המקדש 5:18 )

  • Rav Ashi rules that Tefillin must placed it on the left arm, because it is weaker than the right and the action of placing them should be performed with the stronger right hand (מנחות לז, א).

  • The Talmud teaches that a right-handed person who writes with her left hand on Shabbat has not violated the prohibition against writing. It doesn't count. Maimonides (הלכות שבת 11:14) agrees:

הַכּוֹתֵב בִּשְׂמֹאלוֹ אוֹ לְאַחַר יָדוֹ בְּרַגְלוֹ בְּפִיו וּבְמַרְפֵּקוֹ פָּטוּר

  • According to Rava, walking should start with the right leg, and not the left (יומא יא, ב)

  • The rite of חליצה must be performed with the right leg and a right shoe (יבמות קד, א).

  • The mezuzah can only be placed on the right side of the door (רמבם הל׳ מזוזה 6:12).

  • The best student of a rabbi should walk on the rabbi's right side, relegating the second best to the left (יומא לז, א).

  • After observing his teacher Rabbi Yehoshua, Rabbi Akiva taught that the left hand should be used after using the bathroom, out of respect to the right hand (ברכות סב,ב). When challenged as to why Rabbi Akiva was impertinent enough to report on which hand his teacher wiped himself he replied תורה היא וללמוד אני צריך - "this too is Torah, and I must study it".

לֵ֤ב חָכָם֙ לִֽימִינ֔וֹ וְלֵ֥ב כְּסִ֖יל לִשְׂמֹאלֽוֹ׃

A wise man’s mind tends toward the right hand, a fool’s toward the left.

— Kohelet 10:2

It's not Just Judaism

  1. Islam

The importance of all things right handed is found in other religions. For example, when Muslims perform any of the following, it is mustahabb [مستحبّ‎, - "recommended"] to start on the right or use the right hand.

  • putting on one's garment and pants and shoes

  • entering the mosque, using the siwaak [ a kind of toothpick]

  • putting on kohl [an ancient blue eye cosmetic]

  • clipping the nails

  • trimming the mustache

  • combing the hair plucking the armpit hair

  • shaving the head

  • saying salaam at the end of prayer

  • washing the limbs when purifying oneself

  • exiting the toilet, eating and drinking

  • shaking hands

  • touching the Black Stone [ٱلْحَجَرُ ٱلْأَسْوَد‎, al-Ḥajaru al-Aswad, a rock set into the eastern corner of the Kaaba, the ancient building located in the center of the Grand Mosque in Mecca, Saudi Arabia. Legend has it that the rock dates back to Adam and Eve.]

  • Conversely, the Bukhari Sharif , one of the six major hadith collections of Sunni Islam rules along the lines of Rabbi Akiva:

"... when you urinate, do not touch your penis with your right hand. And when you cleanse yourself after defecation, do not use your right hand."

The right hand of the Messenger of Allah (peace and blessings of Allah be upon him) was for his purification and food, and his left hand was for using the toilet and anything that was dirty...
— Sunan Abi Dawood (33)

2. Christianity

3. Hinduism

  • Offerings, such as flowers or garlands, are carried with both hands on the right side of the body.

  • "Pointing with the forefinger of the right hand or shaking the forefinger in emphasis while talking is never done. This is because the right hand possesses a powerful, aggressive pranic force, and an energy that moves the forces of the world."

  • Vāmācāra ( वामाचार, meaning "left-handed attainment" in Sanskrit) describes the "Left-Hand Path" or "Left-path" It is used to describe a particular mode of worship that is heterodox to standard Vedic teachings.

  • In Benares, the holiest of the seven sacred cities and sitting on the Ganges, "pilgrims circumambulate with their right hands towards the center, as Krishna is alleged to have done at the sacred mountain."

Well, you get the point.  Judaism, along with all the major religions (and some you've never heard of) emphasize the dominance of the right hand in all things holy. Or mundane.

The Ngaga of southern Borneo believe everything in the after-world is reversed, “sweet” becoming “bitter”, “straight” becoming “crooked”, and “right” becoming “left”. Likewise the Toraja of Celebes (Sulawesi) believed the dead do everything backwards, even pronouncing words backwards... the dead therefore use their left hand...
— I. C. Mcmanus. Right Hand, Left Hand: The Origins of Asymmetry in Brains, Bodies, Atoms and Cultures. Phoenix 2003, p27.

 and It's not just religions

There are lots of things that have chirality - meaning they have a mirror image but cannot be mapped onto that mirror image by rotations and translations. They exist in left or right-handed versions. Let's start with in easy example. Um, your hands. Although your right hand mirrors your left, your right hand cannot (comfortably) fit into a handed-glove.

From here.

From here.

Here's another example. Bend your fingers and extend your thumb as in the figure. You've made two mirror images that cannot be mapped onto each other. (Go on. Give it a try. See what I mean?) That's chirality.

If we extend this to molecules, they are left or right-handed, meaning they are mirror images but they cannot be superimposed on each other. These are isomers. Like this:

From here.

From here.

And here is where things start to get really weird. Nearly everything in the universe - from chemicals and medications to fundamental particles and even galaxies themselves have a right-handed or left-handed preference. No, really. 

Let's start with the essential building blocks of life: amino acids and sugars. Almost all amino acids (not you, glycine) used by life on earth (but not necessarily elsewhere in the universe) are left-handed.  Right-handed amino acids exist of course. They're just not utilized by any life form on earth. Any.  If you sit in a lab and cook up an amino acid from its ingredients, you will make an equal amount of the left and right handed variates. That's just good old chemistry at work. But life on earth can only use half the mixture: the L form. Some bacteria can actually convert right-handed amino acids into the left-handed version, but they can’t use the right-handed ones as is.

Like amino acids, sugars also come in two isomers, but those that are used by life forms on earth are the right-handed variety. All the enzymes that living things use to manipulate amino acids and sugars only work on left-handed amino acids and right-handed sugars. They simply can't use the opposites. Why did life turn out this way? Truth is, nobody knows.  

Medications also exhibit chirality. For example, propranolol is commonly used to help control high blood pressure. Some of you reading this may be taking it. The left form (L-propranolol) is the one that helps. The right form (known as D-propranolol) is inactive. (The Latin for left and right is laevus and dexter, respectively.)

Quinine is an antimalarial drug. It has an isomer called quinidine, and quinidine has no anti-malarial action. But it's a great drug to reduce arrhythmias of the heart. One compound, with two isomers, each with their own remarkable and very different healing properties.

Now consider muons, a fundamental particle in our universe. It is kind of like an electron, but about 200 times heavier. Muons have an average life-expectancy of 2.2 microseconds (so don't expect any kind of long-term relationship) after which time they decay into an electron, a neutrino, and an antineutrino. The direction that the electron will come out depends on the direction in which the muon spins. Now you would expect there to be equal amounts of electrons that are ejected spinning one way or another. But there aren't.  What happens is that 99.9% of muons decay in a right-handed fashion.

And while we are on the subject of decaying muons, let's talk about those neutrinos, which are a weird fundamental particle with the smallest mass of any known thing. They too, have a preference for the right or left. All neutrinos are left handed, while all anti-neutrinos (whatever that means) are right handed.

Left and right handed galaxies. From here.

Left and right handed galaxies. From here.

Ready for more? Statistically speaking our universe should contain an equal amount of left and right handed galaxies (as noted in how they spin). But this does not occur. In an analysis of over 2,600 nearby spiral galaxies and a later analysis of 15,000 more, Michael Longo demonstrated that that left-handed spirals are more common in the northern hemisphere, above the northern galactic pole. And although the signal is less strong, right-handed spirals appear more frequently in the south.

It's good to be a leftie

About 10-13% of humans are left-handed. (Captive chimpanzees are more left-handed than us, with an approximate 2:1 ratio of righties to lefties. In us it's more like 8:1) But aside from the problem of not finding scissors that work for you, being a leftie gives you some pretty good advantages.

...not only left-handers are over-represented in confrontational sports, but the closer the physical interaction of the opponents such as in boxing, fencing, judo, or karate, the greater the prevalence of left-handers. In basketball, football, handball, table tennis, tennis, and volleyball, for instance, competitors stand some distance apart and do not confront directly. But even in these sports, there are more than the expected number of left-handers...
— Grouios G. et al. Do left-handed competitors have an innate superiority in sports? Perception and Motor Skills, 2000:90;1273-1282

At the undergraduate level they are more likely to take part in a whole range of events, from judo and fencing and soccer and volleyball. But when it comes to non-confrontational sports like cycle racing, running or swimming, the proportion of left handers fall back to that of the general population. Lefties make up about 10% of the population, but 23% of all Wimbledon tennis champions were lefties.

There is a lot more evidence that lefties have many advantages over (us) righties. In a complicated test of spatial skills which you can read about here, 47 lefties demonstrated faster and more accurate spatial skills than the 50 righties, along with strong executive control and mental flexibility. And in this study of 100 lefties and 100 righties, the left-handed demonstrated greater creativity than the right-handed on all 4 scales of the Torrance test which examines creative thinking.

Obama writes with his left hand.jpg

And lefties appear to be smarter that righties.  In a study of some 300 gifted children, left (or mixed-handedness) occurred more frequently in those who were mathematically or verbally precocious (for our readers in the US, this meant an SAT-M score of more than 700 and an SAT-L score of more than 630). Of the last 15 US presidents, seven (about 47%) have been left-handed.  That's almost 1 in 2! Oh, and compared with righties, college-educated left-handers in the US earn 10-15% more.

Leonardo da Vinci was a lefty, as were Michelangelo, Isaac Newton, and Albert Einstein.

Despite these, and many other advantages, our cultures have stigmatized those who are left-handed. We all know that the word sinister (meaning something harmful or evil is going to happen) comes from the Latin sinister meaning left.  But there are more examples of anti-left associations in other languages too. Adroit, meaning clever or skillful comes from the French word for right droite, meaning dextrous. In German, linkisch means awkward, and it comes from the German links, meaning left. And so it goes on.

Back to the Jewish Bible

Left-handed people are mentioned only three times in Tanach, and all come from the tribe of Benjamin:

  • There were the 700 men from the tribe of Benjamin who could use a sling with deadly accuracy (שופתים 20:16):

מִכֹּ֣ל ׀ הָעָ֣ם הַזֶּ֗ה שְׁבַ֤ע מֵאוֹת֙ אִ֣ישׁ בָּח֔וּר אִטֵּ֖ר יַד־יְמִינ֑וֹ כָּל־זֶ֗ה קֹלֵ֧עַ בָּאֶ֛בֶן אֶל־הַֽשַּׂעֲרָ֖ה וְלֹ֥א יַחֲטִֽא׃

  • There were the ambidextrous men who came to fight for King David at Ziklag, who were from the tribe of Benjamin (דברי הימים א, 12:2)

נֹ֣שְׁקֵי קֶ֗שֶׁת מַיְמִינִ֤ים וּמַשְׂמִאלִים֙ בָּֽאֲבָנִ֔ים וּבַחִצִּ֖ים בַּקָּ֑שֶׁת מֵאֲחֵ֥י שָׁא֖וּל מִבִּנְיָמִֽן׃

  • And perhaps most famously there was the left-handed Ehud ( אֶת־אֵה֤וּד בֶּן־גֵּרָא֙ בֶּן־הַיְמִינִ֔י אִ֥ישׁ אִטֵּ֖ר יַד־יְמִינ֑וֹ) who assassinated the Moabite king Eglon (שופתים 3:12-30). Because Ehud was left-handed he hid his dagger on his right side. In this way he got past the body search outside the throne room, where the guards looked for a weapon on the left. As for the rest, well, read on:

  • וַיִּשְׁלַ֤ח אֵהוּד֙ אֶת־יַ֣ד שְׂמֹאל֔וֹ וַיִּקַּח֙ אֶת־הַחֶ֔רֶב מֵעַ֖ל יֶ֣רֶךְ יְמִינ֑וֹ וַיִּתְקָעֶ֖הָ בְּבִטְנֽוֹ׃ וַיָּבֹ֨א גַֽם־הַנִּצָּ֜ב אַחַ֣ר הַלַּ֗הַב וַיִּסְגֹּ֤ר הַחֵ֙לֶב֙ בְּעַ֣ד הַלַּ֔הַב כִּ֣י לֹ֥א שָׁלַ֛ף הַחֶ֖רֶב מִבִּטְנ֑וֹ וַיֵּצֵ֖א הַֽפַּרְשְׁדֹֽנָה׃

    Reaching with his left hand, Ehud drew the dagger from his right side and drove it into [Eglon’s] belly. The fat closed over the blade and the hilt went in after the blade—for he did not pull the dagger out of his belly—and the filth came out.

All of this is really strange because of course the name of this tribe  - Benjamin - literally means "the son of the right" בן ימין.  

Back to Chhulin

Today's daf yomi page of Talmud has a very short instruction. Give to the priests the most choice of meat cuts: those from the right leg of the animal. But this phrase reveals a profound truth about who we are as humans, and of the very stuff from which we are made.  In culture after culture, in religion after religion, and in the very structure of our universe, there are left or right-handed preferences and predilections, many of which we simply cannot currently explain. Our religious and cultural preferences for the right likely stems from the simple fact that left-handedness is eight times less common. Unfortunately, a suspicion of the other, of those who are not like the majority, is a common trait that in one way or another we all share. But it needn't be so. The other, those in the minority, teach us and enrich our lives. Heck, they are often even smarter and quicker than the majority.  We are all better off with them.

On the Healing Power of Honey, and Happy Rosh Hashanah

Tomorrow evening (or later today if you are in Australia) we will welcome in the start of the Jewish New Year. Among the many traditional foods that are eaten, honey features prominently. Many of us will dip our apples and our challah in it, as we symbolically wish for a sweet new year (and let’s face it, we really need one of those). So in honor of Rosh Hashanah, let’s dig into the Talmudology archives and talk about…honey.

In the Talmud we learn that aside from being delicious, honey was once used as a salve to heal a wound:

שבת עז,ב

דְּבַשׁ כְּדֵי לִיתֵּן עַל הַכָּתִית. תָּנָא: כְּדֵי לִיתֵּן עַל פִּי כָתִית. בָּעֵי רַב אָשֵׁי: ״עַל כָּתִית״ — אַפּוּמָּא דְּכוּלַּהּ כָּתִית, אוֹ דִילְמָא אַמּוּרְשָׁא קַמָּא דְּכָתִית, לְאַפּוֹקֵי הוּדְרָנָא דְּלָא — תֵּיקוּ

We learned in the mishna: The measure that determines liability for carrying out honey is equivalent to that which is used to place on a sore caused by chafing. A tanna taught in a Tosefta: The precise measure is equivalent to that which is placed on the opening of a sore, i.e., on the wound itself. Rav Ashi raised a dilemma: Does the term on a sore mean the measure of honey spread on the opening of the entire sore; or, perhaps it means the measure spread on the primary protuberance of the sore, to the exclusion of the surrounding area upon which he does not spread honey? No resolution was found for this dilemma either. Therefore, let it stand unresolved.

But elsewhere in the Talmud, honey was considered to be bad for a wound:

בבא קמא פה,א 

כדתניא הרי שעבר על דברי רופא ואכל דבש או כל מיני מתיקה מפני שדבש וכל מיני מתיקה קשין למכה והעלה מכתו גרגותני יכול יהא חייב לרפאותו ת"ל רק

It was taught in a Braisa: If the victim of an assault disobeyed the advice of his doctor and ate honey or all types of sweets - and this violated his doctor's instructions because honey and all types of sweets are harmful for a wound - it could be thought that the assailant is still obligated to heal the victim. Therefore the Torah uses the word רק (only) to teach otherwise...(Bava Kamma 85a)

Secretions of the honey bee. From Israili, Z. Antimicrobial Properties of Honey. American Journal of Therapeutics 2014. 21; 304–323.

But certainly according to the Talmud in Shabbat, honey was considered to be beneficial. In fact honey has been used as a medicine for at least the last 3,000 years.  And as we will see, honey has some quite amazing therapeutic uses.

FROM WHERE DOES HONEY COME?

The honeybee is the only insect that produces food eaten by humans. Here is what happens: The female honeybees use their proboscis (a tube-like tongue) to up suck flower nectar and mix it with their saliva and enzymes. Then they store it in a honey sack. Back at the hive, the mixture is regurgitated into cells, dried to about 16% moisture, and stored as a primary food source. As you might expect, the content of the honey depends on a number of factors including the species of bee, the kind of flowers on which they fed, and the conditions in which the honey was stored.

Honey as an Antibiotic

In a review article that focuses on the antimicrobial properties of honey, Zafar Israili from the Emory School of Medicine noted that a large number of laboratory and clinical studies have confirmed the broad-spectrum antimicrobial properties of honey.  These include antibacterial, antifungal, antiviral, and antimycobacterial.  “Honey,” wrote Israili, “was found to be an effective topical treatment for ringworms, athlete’s foot, jock itch, nail fungus, and yeast infections and reported to be comparable to many over-the-counter antifungal preparations.” These properties are likely due to the honey’s acidity, osmotic effect, high sugar concentration, and the presence of chemicals like hydrogen peroxide, antioxidants, and lysozymes.  

Honey contains more than 600 compounds (you can see a list of them here), and the wound healing properties of honey are probably its oldest and best studied medicinal property.  It has been shown to aid wound healing in conditions such as chronic pressure sores, traumatic and diabetic wounds, diabetic foot ulcers, boils, burns, fistulas, necrotizing fasciitis, and a very nasty condition called Fournier’s gangrene. (That's necrosis of the scrotum. Yes, quite gross.) So in contrast to the advice of the talmudic doctors that "honey is bad for an injury", honey turns out to be rather good for wounds, especially when applied directly to them.  But honey isn't just good for wounds...

There is a large body of evidence to support the use of honey as a wound dressing for a wide range of types of wounds. Its antibacterial activity rapidly clears infection and protects wounds from becoming infected, and thus it provides a moist healing environment without the risk of bacterial growth occurring. It also rapidly debrides wounds and removes malodor.

Your Mother was correct

A 2012 study from physicians at the Sackler School of Medicine in Tel Aviv tested the effects of honey on nocturnal cough and sleep quality.  They enrolled 150 children age 1-5 years (and presumably, their tired and exasperated parents) and half an hour before bedtime, gave half of them “a single dose of 10g of eucalyptus honey, citrus honey, or labiatae honey,” and the other half a placebo. (In case you were wondering, as was I, as to what the placebo was, here’s the answer: date extract, “because its structure, brown color, and taste are similar to that of honey.” True enough.) What they found might change the way you treat your own cough this winter. Each of the three honey groups had a better response compared with the date extract, and no significant differences were found among the different types of honey. The authors concluded that honey may be preferable to cough and cold medications for childhood respiratory infections. 

The effect of different types of honey and date extract on cough frequency (I), cough severity (II), cough bothersome to child (III), the child’s sleep (IV), parent’s sleep (V), and combined symptoms score (VI). P <0.05 for the comparisons between group D and the other groups. A, eucalyptus honey; B, citrus honey; C, labiatae honey; D, silan date extract. From Cohen, AH. et al. Effect of Honey on Nocturnal Cough and Sleep Quality: A Double-blind, Randomized, Placebo-Controlled Study. Pediatrics 2012. 130 (3); 465-471.

Honey as a Medicine for Pretty much everything

There are dozens of other medical conditions for which honey may be used. Here is what the review from Israili has to say:

Honey has been reported to be of benefit in a large number of human pathologies including allergy, asthma, bronchitis, common cold, flu, hay fever, nasal congestion, rhinitis, sinusitis, upper respiratory infections, sore throat, cough, fatigue, anxiety, migraine (stress related), cuts, lacerations, burns, wounds (venous, arterial, diabetic, malignant), pressure ulcers, malignant ulcers, perianal and gluteofemoral fistulas, bed sores, adult and neonatal postoperative infections, necrotizing fasciitis, pilonidal sinus, insect bites, infections (bacterial including antibiotic-resistant strains and fungal), septicemia, conjunctivitis and other eye diseases, endophthalmitis, acne, chronic seborrheic dermatitis, dandruff, eczema, psoriasis, inflammation, gingivitis, stomach ache, stomach ulcers, digestive disorders, constipation, vomiting, diarrhea, colitis, dehydration, diabetes, osteoporosis, insomnia, chronic fatigue syndrome, anemia, hypertension, immune disorders, multiple sclerosis, cardiovascular disease, hepatitis, tumors, cancer, and radiation/chemotherapy-induced oral mucositis.

You'd have to check the references and decide if the evidence supports claims like this. But in any event, this list supports the observation in the Talmud that honey was used to heal wounds. If only it helped heal the present pandemic.

Chullin 127a (Part II)~ Spontaneous Generation

Gas Gas mouse.jpg

חולין קכז,א

עכבר שחציו בשר וחציו אדמה שאין פרה ורבה

There is a mouse that is hard made from flesh and half from dirt, and does not procreate

The spontaneous generation of the half-mouse

Deep into several pages about ritual impurity, the Talmud mentions in passing this strange creature, which has come to be called the mud-mouse. And what exactly is this strange creature? Here is the explanation of Rashi:

אין פרה ורבה - כלומר שלא היה מפריה ורביה של עכבר לפי שנוצר מאליו  

It does not procreate: This means it does not sexually reproduce, but instead it spontaneously appears.

And here is Rashi from 127b:

יש מין עכבר שאינו פרה ורבה  אלא מעצמו נוצר מאדמה כאשפה המשרצת תולעים

There is a species of mouse that does not reproduce sexually but is spontaneously generated from the earth, just as maggots appear at a garbage site.

The mud-mouse is also mentioned in Sanhedrin (91):


סנהדרין צא, א

צא לבקעה וראה עכבר שהיום חציו בשר וחציו אדמה למחר השריץ ונעשה כלו בשר

Consider the mouse which today is half flesh and half earth, and tomorrow it has become a creeping thing made entirely of flesh.  

Clearly, Rashi and the rabbis of the Talmud believed in spontaneous generation. Here is the opening of the Wiki article on the subject:

Spontaneous generation or anomalous generation is an obsolete body of thought on the ordinary formation of living organisms without descent from similar organisms. Typically, the idea was that certain forms such as fleas could arise from inanimate matter such as dust, or that maggots could arise from dead flesh.

Everyone Believed it

How could the esteemed rabbis of the Talmud believed in this crazy idea of spontaneous generation? The answer is simple. Everyone believed it. Everyone, from the time of Aristotle until Louis Pasteur. Here is Aristotle (d. 322 BCE):

So with animals, some spring from parent animals according to their kind, whilst others grow spontaneously and not from kindred stock; and of these instances of spontaneous generation some come from putrefying earth or vegetable matter. [History of Animals 539a, 18-26.]

Aristotle’s theory of spontaneous generation was as influential as his other teachings in philosophy and natural history; it was accepted with reverence, not only among his contemporaries but well into modern times
— Jan Bondeson. The Feejee Mermaid and other Essays in Natural and Unnatural History. Cornell University Press 1999. p194

The great Roman poet Ovid (43 BCE-17/18 CE) is best known for his work Metamorphosis. It’s a bit of a long read (almost 12,000 lines contained in 15 books), and in it he mentions spontaneous generation three times. Actually, given its length, he probably mentions everything at least three times. Here is an example, from Metamorphosis I, 416-437.

So, when the seven-mouthed Nile retreats from the drowned fields and returns to its former bed, and the fresh mud boils in the sun, farmers find many creatures as they turn the lumps of earth. Amongst them they see some just spawned, on the edge of life, some with incomplete bodies and number of limbs, and often in the same matter one part is alive and the other is raw earth. In fact when heat and moisture are mixed they conceive, and from these two things the whole of life originates. And though fire and water fight each other, heat and moisture create everything, and this discordant union is suitable for growth. So when the earth muddied from the recent flood glowed again heated by the deep heaven-sent light of the sun she produced innumerable species, partly remaking previous forms, partly creating new monsters.

Spontaneous generation was an accepted theory throughout the middle ages and was found in the writings of Arab naturalists, such as Averroes. Sir Francis Bacon, (d.1626) the English "philosopher, statesman, scientist, jurist, orator, and author" accepted the theory. And so did Willam Harvey, who discovered the circulation of the blood,  - at least under certain circumstances.  And why not believe is spontaneous generation? Before the invention of the microscope, it certainly explained how worms, fleas, bees and other insects could appear out of nowhere.

Well, not quite everyone

In his commentary to the Mishnah on today’s page of Talmud, Maimonides has this to say:

והויות העכבר בלבד מן האדמה עד שימצא קצתו בשר וקצתו עפר וטיט והוא ענין מפורסם מאד אין מספר לרוב המגידין לי שראו זה אע"פ שמציאות בעל חיים כזה דבר מתמיה ולא נודעת בו טענה בשום פנים

The case of the mouse which uniquely grows from the earth so that it is half-flesh and half dust and mud is very well known. There is no end to the countless numbers of those who have told me that they have seen it, even though the existence of this creature is astonishing, and there is no known explanation for it.

Maimonides did not reject the idea that the mouse grows directly from the earth, but he seems very sceptical of the idea. Still, it was a widely accepted explanation for centuries before, and centuries after Maimonides. For example, let’s consider…

Jan Baptista van Helmont and the recipe to grow a mud-mouse

Jan Baptista van Helmont (1580-1644) knew a thing or two about science. Although still deeply embedded in alchemy, his many observations led the way to the scientific revolution. He was the first to suggest that the stomach contained somethings to aid in digestion (what we call today enzymes and acids). And according to the Science History Institute, “he discovered that chemical reactions could produce substances that were neither solids nor liquids and coined the term gas to describe them.” “I call this spirit,” he wrote, “hitherto unknown, by the new name of gas…"(Hunc spiritum, incognitum hactenus, nero heroine Gas voco). This laid the groundwork for Robert Boyle’s later research on gases.

Spontaneous generation also occupied Van Helmont’s scientific worldview. Like everyone else, he believed in it, because it explained observations like fleas appearing around rotting meat or mice appearing in a farmer’s barn of grain. He was so certain of the reality of spontaneous generation that he provided a recipe to grow mice de novo.

If a dirty shirt is stuffed into the mouth of a vessel containing wheat, within a few days, say 21, the ferment produced by the shirt, modified by the smell of the grain, transforms the wheat itself, encased its husk into mice.

Pasteur's Experiments

Then came the microscope. Using one, in October 1676, Leeuwenhoek reported finding tiny micro-organisms in lake water. Now perhaps there was another explanation for how things were created, although not much progress was made for a couple of hundred more years.  It was Louis Pasteur (d.1895) who finally disproved the theory of spontaneous generation with some elegant experiments. He boiled a meat broth in a flask like this, with its neck pointed downwards.

Sanhedrin 91. Spntaneous Generation.jpeg

Boiling sterilized the mixture, and with the neck pointing down, no organisms could contaminate the broth. As a result, there was no growth of bacteria or could inside the flask. He did the same using a flask with a neck that was upturned. This allowed the broth to become contaminated with organisms in the outside air, and the mixture soon became cloudy. Spontaneous generation had been disproven.

The Rabbi who tried to get it right, but got it wrong

Israel Lipschutz of Danzig (1782-1860) wrote a very important two-part commentary on the Mishnah called Tiferet Yisrael. In it, R. Lipschutz got very excited about this whole mouse thing:

ואני שמעתי אפיקורסים מלגלגין על בריה זו שנזכרת כאן ובסנהדרין [דצ"א א']. ומכחישים ואומרים שאינה במציאות כלל לכן ראיתי להזכיר כאן מה שמ"כ בספר אשכנזי שחיבר חכם אחד מפורסם בחכמי האומות. ושמו. לינק. בספרו הנקרא אורוועלט חלק א' עמוד 327. שנמצא בריה כזאת בארץ מצרים במחוז טחעבאיס. ונקראת העכבר ההיא בלשון מצרים דיפוס יאקולוס . ובל"א שפרינגמויז. אשר החלק שלפניה ראש וחזה וידיה מתוארים יפה. ואחוריה עדיין מגולמים ברגבי ארץ. עד אחר איזה ימים תתהפך כולה לבשר. ואומר מה רבו מעשיך ה

I have heard heretics mocking the existence of this creature, mentioned here and in the Talmud Sanhedrin. They deny its existence and claim it is not in any way real. So I have found it appropriate to mention here what is published in a German book written by one of the wisest and most well-known of any nationality, named Link. In his book Urwelt (Part I p327) he states that such a creature was indeed found in the district of Thebais in Egypt. In Egyptian this mouse is called Dipus Jaculus, and in German it is called the spring-mouse. Its head, chest and front paws are well-formed, but its rear is still unformed and is just bits of earth. But after a few days, the mouse becomes made entirely of flesh. And I said “Lord, how great are your works!” (Ps.104:24)

So according to R. Lipschutz all the scoffers were wrong, and as proof he cites his contemporary, the well respected naturalist Johan Heinrich Link (1738–1783), whose Die Urwelt und das Altertum, erläutert durch die Naturkunde (Prehistoric times and antiquity, explained by natural history) was first published in Berlin between 1820 and 1822. Great. A mid-19th century rabbi and scholar quoting a German naturalist in support of a statement made by the rabbis of the Talmud. Science and Judaism at their best! Well no. Not so fast.

In a paper devoted to this topic, Dr. Sid Leiman noted that the passage cited by R. Lipschutz only appeared in the first edition of Link’s book, and was removed from later ones. But more importantly, R. Lipschutz misread the context of the passage he was citing. Rather than attesting to the reality of the mud-mouse, Link was quoting from a passage in the book Bibliotheca historica by Diodorus Siculas, a Greek historian of the first century. It was Diodorus who was describing what his contemporaries believed. But what about that reference to the Latin and German names for the mouse? Diodorus wrote in Greek and could not not have thought that Dipus Jaculus (Latin) is an Egyptian phrase. Let’s have Prof. Leiman explain:

What happened is that Link added a footnote to the Diodorus passage, in an attempt to account for the belief in the existence of this strange creature in antiquity. Link’s note reads (in translation): “The Springmaus (Dipus Jaculus), which dwells in Upper Egypt and is characterized by very short forelegs, doubtless could lead one to conclude that it is a not yet fully developed creature.” Link was suggesting that the very existence of the Springmaus, or jerboa, a small, leaping kangaroo-like rodent found to this day in the arid parts of North Africa, and characterized by long hindfeet and short forelegs, may have misled the ancients into thinking that the different parts of the body of some mice fully matured at different times…The upshot of this was that Lipschutz was persuaded, quite mistakenly, that the mouse described by the rabbis as being half flesh and half earth was alive and well in nineteenth-century Egypt, as attested by no less a scholar than Professor Link!

Wrong, but for the right reasons

The rabbis of the Talmud were not fools for believing in spontaneous generation. They would have been fools had they not. It was an explanation for many natural phenomena and was believed by heroes of the scientific revolution, along with everyone else, until Pasteur proved them all wrong.

And what about our Rabbi Lipschutz? Let’s give the last word on him to Prof. Sid Leiman.

One would like to think that Rabbi Israel Lipschutz, whose seminal work is everywhere characterized by intellectual honesty, would have retracted his garbled reading of Link if only the error had been brought to his attention.

If only indeed.
