Genesis 32:22

He commanded also the second, and the third, and all that followed the herds, saying, “This is how you shall speak to Esau, when you find him.

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.”

So the present passed over before him, and he himself stayed that night in the camp.

He took them, and sent them over the stream, and sent over that which he had.

Jacob was left alone, and wrestled with a man there until the breaking of the day.

When he saw that he didn’t prevail against him, the man touched the hollow of his thigh, and the hollow of Jacob’s thigh was strained as he wrestled.
