Gid Hanasheh (Hebrew: גִּיד הַנָּשֶׁה Gīḏ hanNāše, literally "forgotten sinew", often translated as "displaced tendon") is the term for sciatic nerve in Judaism.
At the end of the fight, the angel strikes a nerve in Jacob's leg, causing him to limp.
The verse then states: "Therefore the Israelites do not eat the displaced nerve (gid ha-nasheh) on the hip joint to this very day."
While most evil urges can be overcome, there is one lust that is so strong that it overpowers even great men - the gid ha-nasheh.
This potential reduction in expense is part of a project that began in Melbourne to create a herd of ben pekuah animals.
