Genesis 32:31

26 And he said, Let me go, for the day breaketh. And he said, I will not let thee go, except thou bless me.

27 And he said unto him, What is thy name? And he said, Jacob.

28 And he said, Thy name shall be called no more Jacob, but Israel: for thou hast striven with God and with men, and hast prevailed.

29 And Jacob asked him, and said, Tell me, I pray thee, thy name. And he said, Wherefore is it that thou dost ask after my name? And he blessed him there.

30 And Jacob called the name of the place Peniel: for, [said he], I have seen God face to face, and my life is preserved.

31 And the sun rose upon him as he passed over Penuel, and he limped upon his thigh.

32 Therefore the children of Israel eat not the sinew of the hip which is upon the hollow of the thigh, unto this day: because he touched the hollow of Jacob`s thigh in the sinew of the hip.
