When the man saw that he could not defeat Jacob, he struck the socket of his hip so the socket of Jacob’s hip was dislocated while he wrestled with him.
That is why to this day the Israelites do not eat the sinew which is attached to the socket of the hip, because he struck the socket of Jacob’s hip near the attached sinew.
This is what the Lord says, the Holy One of Israel, the one who formed him, concerning things to come: “How dare you question me about my children! How dare you tell me what to do with the work of my own hands!
