Genesis 32:23

21So the present passed over before him, and he himself stayed that night in the camp.

22He 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.

23He took them, and sent them over the stream, and sent over that which he had.

24Jacob was left alone, and wrestled with a man there until the breaking of the day.

25When 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.
