Genesis 32:23-25

And he took them, and sent them over the brook, and sent over that he had. {sent them: Heb. caused to pass} And Jacob was left alone; and there wrestled a man with him until the breaking of the day. {breaking...: Heb. ascending of the morning} And 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.
