Genesis 32:23 (KJV)

Then thou shalt say, They be thy servant Jacob's; it is a present sent unto my lord Esau: and, behold, also he is behind us.

And so commanded he the second, and the third, and all that followed the droves, saying, On this manner shall ye speak unto Esau, when ye find him.

And say ye moreover, Behold, thy servant Jacob is behind us. For he said, I will appease him with the present that goeth before me, and afterward I will see his face; peradventure he will accept of me.

So went the present over before him: and himself lodged that night in the company.

And he rose up that night, and took his two wives, and his two womenservants, and his eleven sons, and passed over the ford Jabbok.

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

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.

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

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

And he said, Thy name shall be called no more Jacob, but Israel: for as a prince hast thou power with God and with men, and hast prevailed.
