Genesis 32:22-29

Now he arose that same night and took his two wives and his two maids and his eleven children, and crossed the ford of the Jabbok. He took them and sent them across the stream. And he sent across whatever he had. Then Jacob was left alone, and a man wrestled with him until daybreak. When he saw that he had not prevailed against him, he touched the socket of his thigh; so the socket of Jacob’s thigh was dislocated while he wrestled with him. Then he said, “Let me go, for the dawn is breaking.” But he said, “I will not let you go unless you bless me.” So he said to him, “What is your name?” And he said, “Jacob.” He said, “Your name shall no longer be Jacob, but Israel; for you have striven with God and with men and have prevailed.” Then Jacob asked him and said, “Please tell me your name.” But he said, “Why is it that you ask my name?” And he blessed him there.
