A Long-Forgotten Jewish Remedy for the Coronavirus Outbreak

In the last century there was a particularly Jewish response to a life-threatening epidemic. It was known in Yiddish as the Shvartze Chassaneh, the Black Wedding, and took place in response to the terrible waves of cholera, typhus, and influenza that ravaged the Jews of Eastern Europe, Israel, and North America.

The ceremony was simple: a man and women, each unmarried and either impoverished, orphaned, or disabled (sometimes all three) were married together as husband and wife under a huppah – in a cemetery. The couple’s new home was established with donations by the community. With this act of group hesed, it was hoped that the plague would be averted…

Berachot 40 ~ “Drink Water and You Will Not be Harmed”

ברכות מ, א

אָמַר רָבָא בַּר שְׁמוּאֵל מִשְּׁמֵיהּ דְּרַבִּי חִיָּיא … וְאַחַר כׇּל שְׁתִיָּיתְךָ שְׁתֵה מַיִם וְאִי אַתָּה נִזּוֹק. תַּנְיָא נָמֵי הָכִי:… שְׁתֵה מַיִם וְאִי אַתָּה נִזּוֹק.

תָּנוּ רַבָּנַן: הַמַּקְפֶּה אֲכִילָתוֹ בְּמַיִם, אֵינוֹ בָּא לִידֵי חוֹלִי מֵעַיִם. וְכַמָּה? אָמַר רַב חִסְדָּא: קִיתוֹן לְפַת

And Rava bar Shmuel said the following advice in the name of Rabbi Chiyya: …after all drinking, drink water and you will not be harmed. That was also taught in a baraita: … drink water and you will not be harmed.

On the topic of health, the Gemara cites that the Sages taught in a baraita: One who inundates his food with water, i.e., one who drinks a great deal of water, will not come to suffer from intestinal illness. The Gemara asks: And how muchwater? Rav Chisda said: One jug [kiton] per loaf.

There are a lot of myths in medicine. You only use 10% of your brain. (Nope). Reading in dim light ruins your eyesight (not even close). And you should drink at least eight glasses of water a day. Also nonsense.

THe origins of the eight cups per day mantra

It is not clear where the modern myth that a person needs to drink eight cups of water each day originated. In a 2002 review of the topic, Heinz Valtin from Dartmouth Medical School suggested that it may have began with “the renowned nutritionist” Fredrick J. Stare, who was an early champion of drinking at least six glasses of water a day. In 1974 Stare wrote this:

How much water each day? This is usually well regulated by various physiological mechanisms, but for the average adult, somewhere around 6 to 8 glasses per 24 hours and this can be in the form of coffee, tea, milk, soft drinks, beer, etc. Fruits and vegetables are also good sources of water.

OK, so a couple of things to note. First, there is no reference for this assumption. It is just asserted, which isn’t the way medical recommendations should be made. Second, Stare wrote that the water need not be drunk from a glass. “Fruits and vegetables are also good sources of water.” Third, there is a huge difference between “somewhere around 6 to 8 glasses” and “at least eight glasses.” And fourth, Stare’s original claim allowed for coffee, tea, soft drinks, and even beer. But proponents of the eight glasses a day mantra do not permit these other beverages as part of their eight cups per day regimen.

In fact the recommendation may go further back that Dr Stare. In 1945 the Food and Nutrition Board of the National Research Council wrote:

A suitable allowance of water for adults is 2.5 liters daily in most instances. An ordinary standard for diverse persons is 1 milliliter for each calorie of food. Most of this quantity is contained in prepared foods.

According to Valtin from Dartmouth, that the last sentence was ignored, “and the recommendation was therefore erroneously interpreted as eight glasses of water to be drunk each day.”

No, You don’t need to Drink eight cups of water each day

So much for the history. What evidence is there to support the claim? Not much. Consider for example, a very large study in the Netherlands in the 1980s and published in the British Journal of Nutrition in 2010. Researchers followed over 120,000 individuals for a period of 10 years, and studied the relationships between fluid intake levels and mortality from heart attack and stroke. They found no link between total fluid intake or water intake and either cause of mortality. They also reported that coffee consumption was inversely associated with mortality from ischemic heart disease in women only, while a higher tea intake was associated with lower mortality in men only. So basically, tea and coffee are sexist.

Fluids don’t do much for your kidney function, and there is no evidence that coffee makes you dehydrated. Also, according to Israeli dermatologists, they don’t do anything for your looks. Sorry.

We have discussed the terrible state of nutrition research before, and noted that for many foods there are conflicting recommendations about whether or not they are good for you. Water is no different, and so it is no surprise to find a study that suggests drinking lots of water is indeed beneficial. In 2002 the American Journal of Epidemiology published the results of the Adventist Health Study, which had followed over 20,000 people since the mid 1970s. Among the findings were that high daily intakes of water (five or more glasses) compared with low (two or fewer glasses) were associated with a decreased risk of heart disease in both men (RR=0.46 95% confidence interval (CI): 0.28, 0.75;) and women, (RR= 0.59 95% CI: 0.36, 0.97). Also, A high fluid intake is associated with a decreased risk of bladder cancer in men. Maybe.

How-to books, beauty journals, the Internet, and the media usually recommend drinking six to eight glasses of water each day for keeping the skin hydrated, helping it look healthier, and making it less prone to wrinkles. We have found no scientific proof for this recommendation; nor is there proof, we must admit, that drinking less water does absolutely no harm. The only certainty about this issue is that, at the end of the day, we still await scientific evidence to validate what we know instinctively to be true—namely, that it is all a myth.
— Ronni Wolf, Danny Wolf, Donald Rudikoff, Lawrence Charles Parish. Nutrition and water: drinking eight glasses of water a day ensures proper skin hydration—myth or reality?. Clinics in Dermatology 2010. 28 (4): 380-383.

Having now studied today’s page of Talmud we are able to add to the important literature on the origins of the eight cups per day myth. It didn’t start in the 1970s or even the 1940s. It began with Rabbi Chiyya in the Babylonian Talmud, and his recommendation to drink a jug of water with every loaf of bread.

הנה ימים באים נאם אדני יהוה והשלחתי רעב בארץ לא רעב ללחם ולא צמא למים כי אם לשמע את דברי יהוה

A time is coming—declares my Lord God—when I will send a famine upon the land: not a hunger for bread or a thirst for water, but for hearing the words of the Lord.
— Amos 8:11

Tu Bishvat ~ The Roots of a Palm Tree

According to the Hebrew calendar, today is the fifteenth day of Shevat, and is celebrated as the New Year for Trees. In honor of this we present a re-post about the roots of the Date Palm tree.

בבא בתרא כז ,ב

אמר עולא אילן הסמוך למצר בתוך שש עשרה אמה גזלן הוא ואין מביאין ממנו בכורים עשרה אמה... ותו לא והא תנן מרחיקין את האילן מן הבור כ"ה אמה אמר אביי מיזל טובא אזלי אכחושי לא מכחשי אלא עד שש עשרה אמה טפי לא מכחשי

Ulla said: An individual who owns a tree that is within sixteen cubits of a boundary is a robber, [since it draws nourishment from the neighbor’s land,] and one does not bring first fruits from it, [since that would be a mitzva that is fulfilled by means of a transgression]... But do roots extend sixteen cubits and no more? Didn’t we learn in a Mishnah (25b): One must distance a tree twenty-five cubits from a cistern? [This indicates that tree roots reach more than sixteen cubits.] Abaye said: The roots extend farther, but they drain the earth of nutrients within sixteen cubits; with regard to an area any more distant than that, they do not drain the earth.

The Root Systems of the Date Palm Tree

While the Talmud doesn't specify the kind of tree that must be distanced from others, in Mesepotamia the most likely candidate was the Date PalmPhoenix dactylifera. These trees grow to a height of 75 feet, and you've seen plenty of them if you've driven south towards Eilat.  Here is their root system:

To whom shall we turn to get information about the size of that root system? The United Nations Food and Agriculture Organization, of course.  According to a helpful document by a member of their Date Production Support Programme, "Roots are found as far as 25m from the palm and deeper than 6m, but 85 percent of the roots are distributed in the zone of 2 m deep and 2m on both lateral sides in a deep loamy soil." But the 25m (82 foot) roots are an extreme. Most of the roots extend about 10m (about 32 feet).

Table from here.

It would appear that Abaye was referring to the average reach of the zone II roots. Assuming that a talmudic amah is between 48-57cm, Abaye's figure would put the zone II distance of at 7.6-9.1 m. That's right in keeping with the 10m average figure from the UN document. It is good to know that on these important matters, the UN and the Jewish People are in agreement.

Berachot 34b ~ Where on Earth is the Garden of Eden?

From here.

From here.

In today’s page of Talmud the rabbis seek to explain the meaning of the verse found in Isaiah (64:3)

וּמֵעוֹלָם לֹא־שָׁמְעוּ לֹא הֶאֱזִינוּ עַיִן לֹא־רָאָתָה אֱלֹהִים זוּלָתְךָ יַעֲשֶׂה לִמְחַכֵּה־לוֹ׃ 

Such things had never been heard or noted. No eye has seen [them], O God, but You, Who act for those who trust in You.

According to Rabbi Yochanan this refers to the reward that God has in store for those who are completely (and not just mostly) righteous. Rabbi Yehoshua ben Levi gave a more alcohol suffused explanation. It refers to wine that has been preserved in its grapes since the six days of creation, and which, apparently, no eye has ever seen. And then comes this third explanation, which explained the verse geographically.

ברכות לד, ב

. רַבִּי שְׁמוּאֵל בַּר נַחְמָנִי אָמַר: זֶה עֵדֶן, שֶׁלֹּא שָׁלְטָה בּוֹ עֵין כׇּל בְּרִיָּה. שֶׁמָּא תֹּאמַר: אָדָם הָרִאשׁוֹן הֵיכָן הָיָה? בַּגָּן. שֶׁמָּא תֹּאמַר: אָדָם הָרִאשׁוֹן הֵיכָן הָיָה? בַּגָּן. וְשֶׁמָּא תֹּאמַר: הוּא גַּן, הוּא עֵדֶן, תַּלְמוּד לוֹמַר: ״וְנָהָר יוֹצֵא מֵעֵדֶן לְהַשְׁקוֹת אֶת הַגָּן״, גַּן לְחוּד וְעֵדֶן לְחוּד

Rabbi Shmuel bar Nachmani said: That is Eden, which no creature’s eye has ever surveyed. Lest you will say: Where was Adam the first man? Wasn’t he there and didn’t he survey Eden? The Gemara responds: Adam was only in the Garden of Eden, not in Eden itself. And lest you will say: It is the Garden and it is Eden; two names describing the same place. That is not the case, as the verse states: “And a river went out from Eden to water the Garden” (Genesis 2:10). Obviously, the Garden exists on its own and Eden exists on its own. 

So according to Rabbi Shmuel bar Nachmani, the Garden of Eden was actually two places, one called the Garden, and one called Eden. And no one has seen either.

John Calvin’s Hunt for the Location of the Garden of Eden

It wasn’t only Jews who wondered where the Garden of Eden was, (and for now let’s just assume they are one and the same, geographically). The great Church reformer John Calvin (d. 1564) opined on the question too.

Moses says that one river flowed to water the garden, which afterwards would divide itself into four heads. It is sufficiently agreed among all, that two of these heads are the Euphrates and the Tigris; for no one disputes that . . . (Hiddekel) is the Tigris. But there is a great controversy respecting the other two. Many think, that Pison and Gihon are the Ganges and the Nile; the error, however, of these men is abundantly refuted by the distance of the positions of these rivers. Persons are not wanting who fly across even to the Danube; as if indeed the habitation of one man stretched itself from the most remote part of Asia to the extremity of Europe. But since many other celebrated rivers flow by the region of which we are speaking, there is greater probability in the opinion of those who believe that two of these rivers are pointed out, although their names are now obsolete. Be this as it may, the difficulty is not yet solved. For Moses divides the one river which flowed by the garden into four heads. Yet it appears, that the fountains of the Euphrates and the Tigris were far distant from each other…

What Calvin is getting at is that the Bible suggests that the location of the Garden of Eden is at a point where four large rivers in the levant flow into one, and there is no such place. Perhaps, Calvin goes on to suggest, the geography changed as a result of the Great Flood.

And the Hunt of the Ben Ish Chai

One famous rabbi spent some time pondering the same question that so consumed Calvin. This rabbi was Joseph Hayyim (1834–1909) who was born in Baghdad, and at the age of twenty-five succeeded his father as leader of the Jewish community there. He authored a work that is widely read by Sephardic Jews to this day called Ben Ish Chai (The Son of Man Lives), and by which Hayyim came to be called. The book is a collection of halakhah and ethical discourses based on the weekly portion read from the Torah. In addition, he published three volumes of responsa between 1901 and 1905 called Rav Pe’alim (Many Acts); a fourth volume was posthumously published in 1912.

In an undated question, the Ben Ish Chai was asked about the location of the Garden of Eden. In one tradition, the garden was located “on the other side of the world,” somewhere below the equator in the southern hemisphere. However, the questioner continued, the world has been circumnavigated, and the Garden of Eden has not been identified. Where then is it located?

He began his answer by pointing out that the sages of the Talmud did not travel far and had certainly never explored the entire globe. He quoted from the eighteenth century work Sefer Haberit, which seems to have been the only text from which the Ben Ish Chai drew his scientific information, and claimed that although the evidence suggested that the world was indeed a globe, the matter was still disputed. It was on this supposed dispute that Ben Ish Chai built his criticism of the scientific method. “Everything is built on conjecture,” he claimed, and scientific explanations were constantly being overturned or revised. He appealed to an argument that had been made by several other skeptics of the Copernican idea that the Earth did not lie the center of the universe.

Even when [a scientific idea seems] persuasive, it is likely to be rejected and overturned, because later enlightened people will come to understand something that arises from the natural world that had not been understood by those earlier. [These earlier people] had invented their own system based on their understanding. When an objection to an earlier system arises, the entire system is destroyed, because when a foundation is destroyed the whole house crumbles. This is very common, and we see generation after generation adding to the understanding of the natural world. It is like a dwarf standing on the shoulders of a giant, and later generations see further than those who came earlier. Over the last two thousand years a number of systems have been developed and overridden in the fields of natural sciences and astronomy. One builds and another destroys, like the building of [the Egyptian cities of] Pitom and Ramses.

There were grounds therefore to be deeply skeptical of scientific claims about the world. Part of this may be due to the limitations of the human senses, but it was the very way in which science progressed - or the way in which he thought that it progressed, that led to skepticism of the Ben Ish Chai. He then turned to the question of the geocentric Earth and claimed that there was a continuing scientific controversy about whether the Earth or the Sun was stationary. Because the proofs, such as there were, were based on conjecture, the matter remained unsolved. The Ben Ish Chai was also unimpressed by the ability of astronomers to predict the precise times of future solar eclipses. He subscribed to a widely held myth that all science originated with the Jews, and claimed that any predictive ability demonstrated by astronomers was a result of Jewish knowledge of the stars and planets having been passed from Adam down to Noah and Abraham and then out into the world at large. This would explain why astronomers could accurately predict many events, but it in no way proved that their theoretical models were correct. In fact, the Ben Ish Chai remained deeply suspicious not only of the assertion that the Earth revolved around the stationary Sun, but of all the scientific statements made by astronomers.

So where did the Ben Ish Chai think the Garden of Eden was located?

In his long responsum, the Ben Ish Chai eventually returned to answer the original question about the location of the Garden of Eden and noted that, although it may be located on the Earth itself, it existed on a different spiritual plane and would therefore not be perceived by the human senses. Of course, this was all that needed to be said for the original question to have been addressed. The rest of the responsum, criticizing the truth claims of science, was irrelevant, but he had used the opportunity to explain his thoughts on the matter. As a result of his skepticism, he remained in doubt as to which model of the universe was correct, and he implied that the reader should adopt a similarly skeptical approach to science. Interestingly, the Ben Ish Chai did not address any of the nineteenth-century scientific demonstrations that supported the Copernican model, like Foucault’s pendulum or Bessel’s demonstration of stellar parallax, and there is no evidence that he knew of them.

Unfortunately, the Ben Ish Chai had a conception of scientific progress that was not accurate. Although scientific explanations do indeed change, it is only rarely the case that this happens in the drastic way he described: “like an edifice that comes crashing down because of its weak foundation.” Much more often, new scientific theories or explanations modify those that already exist, so that they better fit experimental data or observations. Such modifications do not destroy the earlier theories, as the Ben Ish Chai would have us believe, but allows them to have greater explanatory power.

And as for that elusive search for the Garden of Eden? Rabbi Shmuel bar Nachmani seems to have been correct all along. So far as we know, no human eyes have seen it.
