Genesis Chapter 32 World English Bible

You shall say, 'Not only that, but behold, your servant, Jacob, is behind us.'" For, he said, "I will appease him with the present that goes before me, and afterward I will see his face. Perhaps he will accept me."
Therefore the children of Israel don't eat the sinew of the hip, which is on the hollow of the thigh, to this day, because he touched the hollow of Jacob's thigh in the sinew of the hip.
