23And he took them, and sent them over the brook, and sent over that he had.

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

25And when he saw that he prevailed not against him, he touched the hollow of his thigh; and the hollow of Jacob's thigh was out of joint, as he wrestled with him.

26And he said, Let me go, for the day breaketh. And he said, I will not let thee go, except thou bless me.
