اَلتَّكْوِينُ 32:32

لِذَلِكَ لَا يَأْكُلُ بَنُو إِسْرَائِيلَ عِرْقَ ٱلنَّسَا ٱلَّذِي عَلَى حُقِّ ٱلْفَخْذِ إِلَى هَذَا ٱلْيَوْمِ، لِأَنَّهُ ضَرَبَ حُقَّ فَخْذِ يَعْقُوبَ عَلَى عِرْقِ ٱلنَّسَا.

Therefore the children of Israel eat not of the sinew which shrank, which is upon the hollow of the thigh, unto this day: because he touched the hollow of Jacob’s thigh in the sinew that shrank.
