Genesis 32:27-32

So He asked him, “What is your name?” And he said, “Jacob.” And He said, “Your name shall no longer be Jacob, but Israel; for you have struggled with God and with men and have prevailed.” [Hos 12:3, 4] Then Jacob asked Him, “Please tell me Your name.” But He said, “Why is it that you ask My name?” And He declared a blessing [of the covenant promises] on Jacob there. So Jacob named the place Peniel (the face of God), saying, “For I have seen God face to face, yet my life has not been snatched away.” Now the sun rose on him as he passed Penuel (Peniel), and he was limping because of his hip. Therefore, to this day the Israelites do not eat the tendon of the hip which is on the socket of the thigh, because He touched the socket of Jacob’s thigh by the tendon of the hip.
