Mishneh Torah, Forbidden Foods 8-10

Hook

In the wrestling of Jacob with the angel, the Gid HaNeseh (sciatic nerve) was struck—an intimate, visceral marker of a divine encounter that permanently altered the dietary landscape of his descendants.

Context

• Source: Rambam (Maimonides), Mishneh Torah, Laws of Forbidden Foods (Ma'achalot Assurot), Chapter 8.
• Era: 12th Century, written in Egypt for a global Sephardi/Mizrahi community transitioning from the Talmudic era to codification.
• Community: Sephardic and Mizrahi Jews, who maintained the strict, literal adherence to Rambam’s rulings on the anatomy of the animal and the specific prohibitions of Gid HaNeseh.

Text Snapshot

"The prohibition against partaking of the gid hanesheh applies with regard to kosher domesticated animals and wild beasts... It applies to [the gid] on the right thigh and that on the left thigh. According to Scriptural Law, only [the gid] on the hip socket is forbidden... The remainder of the gid... and similarly, the fat which is on the gid—are forbidden only according to Rabbinic decree."

Minhag/Melody

In many Sephardic and Mizrahi traditions, the meticulous removal of the Gid HaNeseh is a point of communal pride. Unlike some Ashkenazi traditions that may avoid the hindquarters entirely due to the complexity of the nikkur (de-veining) process, many Sephardic butchers remain experts in nikkur, allowing for the consumption of the hindquarters. This reflects the Sephardi commitment to maximizing the utilization of the animal while strictly adhering to the Halakhic requirements of extraction.

Contrast

While Ashkenazi practice often relies on the Minhag (custom) of avoiding the hindquarters entirely—making cuts like sirloin unavailable—the Sephardi/Mizrahi tradition focuses on the Mitzvah of proper removal. It is a difference of chumra (stringency through avoidance) versus hiddur (stringency through precise, skilled performance).

Home Practice

Next time you visit a kosher butcher, ask if they perform nikkur on their hindquarter cuts. If you are in a community where hindquarters are available, learn to identify the gid by observing a professional butcher remove it. Even if you don't eat those cuts, understanding the anatomy of the animal connects you back to the historical reality of the Mishneh Torah.

Takeaway

The prohibition of the Gid HaNeseh is more than a dietary restriction; it is a physical, daily remembrance of Jacob’s struggle. By mastering the extraction of this nerve, we do not just avoid the forbidden—we actively participate in the preservation of a sacred, ancestral boundary.
