Genesis 32:25-27

King James Version

²⁵ 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.

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

²⁷ And he said unto him, What is thy name? And he said, Jacob.
