Tests of one’s nerves[1]
על-כן לא-יאכלו בני-ישראל את-גיד הנשה אשר על-כף הירך עד היום הזה כי נגע בכף-ירך יעקב בגיד הנשה
Therefore, the Children of Israel do not eat the sciatic nerve, which is on the hip of the thigh, until this very day. This is because Yaakov was injured on his hip, in his sciatic nerve[2]
One of the most mysterious encounters in the Chumash is Yaakov’s wrestling match with an unknown man. Their fight lasted the entire night. Our Sages tell us[3] that it was an Angel. Not just any Angel, but the guardian angel of Yaakov’s brother Eisav. Although Yaakov emerged victorious from the struggle, he didn’t escape unscathed. The Angel managed to injure Yaakov’s hip socket. The Torah concludes this episode with the words: “This is why the Jews to this day do not eat the sciatic nerve”. Indeed, this is one of the 613 mitzvos[4], not to eat the sciatic nerve of a kosher animal. What’s the reasoning behind this mitzvah? What are we to learn from it?
