Genesis 32:23

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 rose up that night, and took his two wives, and his two servants, and his eleven sons, and crossed over the ford of the Jabbok.

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.

The man said, “Let me go, for the day breaks.”

Jacob said, “I won’t let you go unless you bless me.”
