Do Not Eat the Sciatic Nerve (Gid HaNasheh)
Jacob’s Wrestling — The Wound That Became a Law
Genesis 32:25: “And Jacob was left alone. And a man wrestled with him until the breaking of the day.” The wrestling match at the Jabbok ford — Jacob alone at night, wrestling a mysterious figure until dawn — is one of the most dramatic and theologically dense narratives in the Torah. Genesis 32:26: “When the man saw that he did not prevail against Jacob, he touched the hollow of his thigh; and Jacob’s thigh was put out of joint as he wrestled with him.” The touch is precise: the hollow of the thigh, where the sciatic nerve runs. The wound is a permanent mark — Jacob walks away limping (Genesis 32:31: “The sun rose upon him as he passed Penuel, limping because of his hip”).
Genesis 32:32: “Therefore the children of Israel do not eat the sinew of the hip which is on the hollow of the thigh, to this day, because he touched the hollow of Jacob’s thigh in the sinew of the hip.” The Torah’s narrative voice steps back from the story and makes a legal observation: this dietary prohibition has been observed since that night. The wound Jacob received is carried by Israel in its body — in its eating habits. Every time an Israelite (and later a Jew) removes the gid ha-nasheh from meat, the memory of Jacob’s wrestling night is renewed.
A Memorial in the Body — The Limp That Never Leaves
Jacob limped away from the Jabbok. The wound in the hollow of his thigh was permanent — the angel had touched the nerve that governs hip mobility. And his descendants carry that wound in their dietary practice: the gid ha-nasheh, the sinew in that same hollow of the thigh, may not be eaten. Israel’s body memory of the patriarchal wound is maintained through a food prohibition that recurs every time hindquarter meat is prepared. The prohibition is not merely a dietary regulation — it is a physical memorial that spans the generations.
This type of memorial — embodied, dietary, regular — is characteristic of how the Torah preserves significant events. The Passover’s matzah recalls the unleavened bread of the Exodus; the Shabbat recalls creation’s seventh day; the Sukkot booths recall the wilderness shelters. The gid ha-nasheh prohibition recalls Jacob’s wound. In each case, the memorial is not merely verbal (a story told) or visual (a monument built) but embodied and recurring — built into the daily or annual cycle of eating and living. The Torah creates memory through practice, not only through narrative.
The Name — Gid HaNasheh and the Mystery of the Opponent
Genesis 32:28: “Then he said, ‘Your name shall no longer be called Jacob, but Israel, for you have striven with God and with men, and have prevailed.’” Jacob’s opponent — the “man” of Genesis 32:25 — gives Jacob a new name but refuses to give his own (Genesis 32:29: “Why is it that you ask my name?”). The renaming of Jacob to Israel — “he who strives with God” — is one of the Torah’s most significant naming events. Jacob the supplanter becomes Israel the God-wrestler; the wound in the thigh is the cost of the encounter and the new name is the reward.
The gid ha-nasheh prohibition thus carries the full weight of this naming event. Israel — the people who bear the name of the God-wrestler — carries in its dietary law the memory of what that wrestling cost. The prohibition is not about the nerve per se but about the hollow of the thigh where the angel’s touch landed. To avoid eating from that place is to honor the encounter — to acknowledge that Israel’s name was bought at a price, that the covenant was secured through a night of struggle that left a permanent mark. The gid ha-nasheh is Israel’s dietary scar.
