Genesis 32:32 YLT

³⁰  And Jacob calleth the name of the place Peniel: for 'I have seen God face unto face, and my life is delivered;'

³¹  and the sun riseth on him when he hath passed over Penuel, and he is halting on his thigh;

³²  therefore the sons of Israel do not eat the sinew which shrank, which 'is' on the hollow of the thigh, unto this day, because He came against the hollow of Jacob's thigh, against the sinew which shrank.
