Genesis 32:25-27

Young's Literal Translation

²⁵ and he seeth that he is not able for him, and he cometh against the hollow of his thigh, and the hollow of Jacob's thigh is disjointed in his wrestling with him;

²⁶ and he saith, `Send me away, for the dawn hath ascended:' and he saith, `I send thee not away, except thou hast blessed me.'

²⁷ And he saith unto him, `What [is] thy name?' and he saith, `Jacob.'
