Genesis 32:24-28

24And Jacob remained alone; and a man wrestled with him until the rising of the dawn.

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

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

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

28And he said, Thy name shall not henceforth be called Jacob, but Israel; for thou hast wrestled with 1God, and with men, and hast prevailed.
