Genesis 32:24-32

Afterwards, Jacob went back and spent the rest of the night alone. A man came and fought with Jacob until just before daybreak. When the man saw that he could not win, he struck Jacob on the hip and threw it out of joint. They kept on wrestling until the man said, “Let go of me! It's almost daylight.” “You can't go until you bless me,” Jacob replied. Then the man asked, “What is your name?” “Jacob,” he answered. The man said, “From now on, your name will no longer be Jacob. You will be called Israel, because you have wrestled with God and with men, and you have won.” Jacob said, “Now tell me your name.” “Don't you know who I am?” he asked. And he blessed Jacob. Jacob said, “I have seen God face to face, and I am still alive.” So he named the place Peniel. The sun was coming up as Jacob was leaving Peniel. He was limping because he had been struck on the hip, and the muscle on his hip joint had been injured. That's why even today the people of Israel don't eat the hip muscle of any animal.
