135-170Yehudah ben Ilai

 

Sayings of Yehuda ben Ilai extracted from the tractates Pesachim and Chullin (Babylonian Talmud). Babylonian Talmud was written between about 450 - 550 in present-day Iraq (formerly Babylonia). The religious scholar Yehuda ben Ilai points out the distal attachment site of the ligamentum capitis femoris (LCF) and demonstrates knowledge of the possibility of its injury. See our commentary at the link: 135-170Yehudah ben Ilai [Rus].

Translation

Quote 1.

[Eng]

Passover Festivals 22a5

The Gemara answers: Whom did you hear that said that sinews do not give flavor? It is Rabbi Shimon, as it was taught in a baraita: With regard to one who eats the sciatic nerve from a non-kosher domesticated animal, Rabbi Yehuda deems him liable to receive two sets of lashes: One for eating the sciatic nerve and one for eating the meat of a non-kosher animal. And Rabbi Shimon exempts him entirely, since according to his opinion the prohibition to eat the sciatic nerve applies only to a kosher animal. In addition, one violates the prohibition of eating from a non-kosher animal only when it has the flavor of meat. (original source: sefaria.org)

Quote 2.

[Eng]

Passover Festivals 83b5

Granted, if you say they are meat, due to that they require burning; but if you say they are not meat, why do they require burning? One should simply discard them like other waste. Rav Ḥisda said: The mishna’s mention of sinews is necessary only for the sciatic nerve, in accordance with the opinion of Rabbi Yehuda. (original source: sefaria.org)

Quote 3.

[Eng]

Passover Festivals 83b6

As it was taught in a baraita that Rabbi Yehuda said: The prohibition to eat the sciatic nerve according to Torah law applies only to the sciatic nerve in one of the animal’s thighs, and not to both, and logic dictates that it is the right thigh. However, since there is no absolute proof that this is correct, the sciatic nerve must be removed from both sides. Although in theory the forbidden sciatic nerve may be discarded and the permitted one may be eaten, since there is uncertainty as to which one is permitted, neither of them may be eaten. Both must be burned. (original source: sefaria.org)

Quote 4.

[Eng]

Passover Festivals 83b7

The Gemara asks: Shall we then conclude that Rabbi Yehuda was uncertain about which sciatic nerve is forbidden? The Sages were unsure whether Rabbi Yehuda was absolutely convinced that it is the sciatic nerve from the right side that is forbidden, or if he was saying that this would seem likely to be the case, but he was not certain. As, if it were clear to him that it is the sciatic nerve from the right thigh that is forbidden, the proper procedure would be different: The one that is permitted we should eat, and the one that is forbidden we should discard. Why should he require burning? (original source: sefaria.org)

Quote 5.

[Eng]

Chullin 91a12

The Gemara asks: And what is the reason that Rabbi Yehuda holds that only the sciatic nerve of the right thigh is forbidden by Torah law? Rava said that it is because the verse states: “Therefore the children of Israel eat not the sciatic nerve that is upon the spoon of the thigh” (Genesis 32:33). The definite article indicates that this is referring to the most important thigh. (original source: sefaria.org)

Quote 6.

[Eng]

Chullin 96a5

MISHNA: One who removes the sciatic nerve must scrape away the flesh in the area surrounding the nerve to ensure that he will remove all of it. Rabbi Yehuda says: Scraping is not required; it is sufficient to excise it from the area above the rounded protrusion in order to thereby fulfill the mitzva of removal of the sciatic nerve. (original source: sefaria.org)

Quote 7.

[Eng]

Chullin 96b2

And according to Rabbi Yehuda, from where is it derived that one is liable for eating one olive-bulk of a larger sciatic nerve? He holds that it is derived from the phrase “that is upon the spoon of the thigh,” which indicates that even if one eats only the part of the sciatic nerve that is upon the spoon of the thigh, rather than the entire sciatic nerve, he is liable. (original source: sefaria.org)

Quote 8.

[Eng]

Chullin 96b3

And how do the Rabbis interpret that phrase? That phrase is necessary to teach the halakha stated by Shmuel, as Shmuel said: The Torah prohibits only the part of the sciatic nerve that is on the rounded protrusion of flesh shaped like a spoon. And what does Rabbi Yehuda hold with regard to the halakha stated by Shmuel? He derives from the fact that it is written: “The spoon of the thigh,” that the sciatic nerve of the entire thigh is forbidden, not just the part that is on the rounded protrusion of flesh shaped like a spoon. (original source: sefaria.org)

Explanation: Chullin 96b4-5

4. And how do the Rabbis interpret “the spoon of the thigh”? According to the Rabbis, this expression indicates that the prohibition of the sciatic nerve applies to the nerve that extends throughout the entire thigh, i.e., the inner nerve, which serves to exclude the outer nerve, which is not forbidden by Torah law; but in fact, only the part of the inner nerve that is on the protrusion of flesh shaped like a spoon is forbidden, not the entire inner nerve. (original source: sefaria.org)

5. The Gemara objects: But this term “spoon” is required to exclude the sciatic nerve of a bird, which does not have a rounded protrusion on its thigh bone that can be described as the spoon of the thigh, as taught in the mishna (89b). The Gemara explains: There are two usages of the term “spoon” written in the verse, and therefore two separate halakhot can be derived from this term. (original source: sefaria.org)

The Solar System

  The Solar System As a result of a mysterious catastrophic event about 13.8 billion years ago, the Universe was formed (2012HawkingS; 2020AghanimN_RoudierG). In it, giant cloud-like accumulations of plasma, molecules and dust became the points of star formation (2011MurrayN). A series of their generations, igniting, functioning and collapsing, led to the appearance of various chemical elements through staged reactions of nuclear fusion (1998IshkhanovBS_TutynIA). The Sun was born for at least ten million years by compressing a concentration of molecular gas and parts of the most ancient stars (2010HanslmeierA). As a result, 4.5682-4.567 billion years ago, the Solar System self-organized, at the dawn of its life consisting of a central luminary and a protoplanetary gas and dust disk (2013HazenRM). At least the oldest meteorite inclusions were fused 4.568-4.565 billion years ago, and at most three million years later, accretion of chondrite globules occurred (1995AllègreCJ_GöpelC). T...
