창세기 32:33 해설: Rashi, Bekhor Shor, Chizkuni & Da'at Zekenim

גיד הנשה THE SINEW OF THE THIGH-VEIN — Why is its name called גיד הנשה? Because it sprang נשה) and rose from its proper position. The word has the meaning of “springing”. Other examples are: (Jeremiah 51:30) “Their strength sprang away (נשתה)” and (41:51) “for God hath made all my trouble spring away from me נַשַּׁנִי)".

It is to be a commemoration for them that their forefather fought with the angel, and [the latter] could not subdue him. And so [the angel] pressed him on the hollow of his thigh, in the place where there is the the sciatic nerve. And it is a commemoration of glory and greatness.

על כן לא יאכלו, “therefore it is appropriate that the Israelites do not eat, etc.;” this construction is parallel to Isaiah 10,7: והוא לא כן ידמה, “but it does not seem like this to him;” in other words: it would be right and proper to punish the Israelites not to eat that particular sinew as they should not have allowed their founding father to be exposed to hostile forces at night. Yaakov’s sons were physically strong, and they should have been at hand to assist their father if the need arose to do so. Seeing that they failed to do this, the blame for the injury sustained by their father was theirs. From now on they would have learned their lesson and would practice the commandment to accompany their father, or for that matter, any older and wiser person, especially at night. Yaakov himself set an example when he accompanied his son Joseph part of the way on a mission which he had sent him on, and which was potentially dangerous. (Genesis 37,14) A different approach to the verse above: as a result of their father Yaakov having stood up to the protective celestial force of Esau, his sons stopped eating the part of the body that the angel had been able to injure. They did this out of a feeling of pride in their founding father. A third approach to this verse: due to their father Yaakov having sustained an injury, his descendants voluntarily decided not to eat the part of the body of an animal that had been injured in their father’s body. This has to be understood better by the use of a parable; a person suffered from a headache or from pains in a different part of his body. As a reminder of that pain he decides not to eat that part of the body of an animal as a symbol of his having been healed from that pain, so that it (abstention) would serve as a remedy for them (preventive medicine) in the future. We have a Baraitah in Chulin 101 which relates that people came to Rabbi Yehudah who had expressed the opinion that the prohibition not to eat that part of an animal also applied to animals that were altogether forbidden to be eaten, questioning his interpretation by citing the fact that only the descendants of Israel were forbidden to eat this part of an animal, and that the Jews had never been called “Children of Israel” until they had been given the Torah at Mount Sinai. He answered them that it is true that this custom did not become law until the Torah was given, but it had been observed already earlier. It was recorded here only in order for us to understand the reason behind this prohibition. Prior to the legislation of dietary laws at Mount Sinai, Yaakov’s descendants were allowed to eat also the meat of animals that were outlawed at Mount Sinai.
