Gid Hanasheh (Hebrew: גִּיד הַנָּשֶׂה) refers to the sciatic nerve, a long nerve extending from the spine down the back of the leg, which holds significant importance in Jewish dietary laws (Kashrut). According to these laws, the Gid Hanasheh is forbidden for consumption by Jews. This prohibition is rooted in the Torah, specifically in the book of Genesis (32:32), which narrates the story of Jacob wrestling with an angel. After Jacob prevails, the text notes that he was struck in the socket of his hip, hence the Israelites do not eat the sinew of the thigh (Gid Hanasheh) to this day.

Biblical Origin

The prohibition originates from the biblical episode where Jacob, the patriarch, wrestles with an angel until dawn. As dawn breaks, the angel, unable to overpower Jacob, strikes him on the hip socket, causing a dislocation. This event leads to the divine commandment that the Israelites should not eat the Gid Hanasheh. The passage in Genesis 32:32 explicitly states, "Therefore the children of Israel do not eat the sinew of the thigh which is on the socket of the hip, to this day; because he touched the socket of Jacob’s hip in the sinew of the thigh."

Halachic Details

In Jewish law (Halacha), the prohibition of Gid Hanasheh is detailed extensively. It is considered a mitzvah (commandment) that encompasses not only the sciatic nerve itself but also certain fats surrounding the nerve. The process of removing the Gid Hanasheh and the forbidden fats is known as Nikkur, and it is a complex and labor-intensive process. Due to the difficulty of properly removing the Gid Hanasheh, many Jewish communities, especially those in the Diaspora, opt to consume only the front quarters of cattle where this nerve does not extend.

Cultural and Religious Significance

The prohibition of Gid Hanasheh is more than a dietary law; it is imbued with deep cultural and religious significance. It serves as a reminder of Jacob's struggle and victory, symbolizing the resilience and perseverance of the Jewish people. The act of abstaining from the Gid Hanasheh commemorates Jacob's encounter, reinforcing the identity and continuity of the Jewish people through the generations.

Contemporary Practice

Today, the observance of this prohibition varies among Jewish communities around the world. In some communities, especially those with access to skilled butchers who can perform Nikkur, the hindquarters of cattle may be consumed after proper preparation. In many Ashkenazi and other communities, however, the hindquarters are generally not used for kosher meat due to the complexity of removing the Gid Hanasheh and the surrounding forbidden fats.

Conclusion

The prohibition of Gid Hanasheh is a unique commandment within Jewish dietary laws, rooted in a historical and spiritual narrative. It exemplifies the intricate relationship between Jewish law, tradition, and the collective memory of the Jewish people. As such, it remains a significant aspect of Jewish dietary practice, reflecting the enduring legacy of the biblical patriarchs and the historical experiences of the Jewish nation.
