Genesis 32:24-27

But Jacob stayed behind by himself, and a man wrestled with him until daybreak. When the man saw that he couldn’t get the best of Jacob as they wrestled, he deliberately threw Jacob’s hip out of joint. The man said, “Let me go; it’s daybreak.” Jacob said, “I’m not letting you go ’til you bless me.” The man said, “What’s your name?” He answered, “Jacob.”
