Genesis 32:26 ASV

²⁴  And Jacob was left alone; and there wrestled a man with him until the breaking of the day.

²⁵  And when he saw that he prevailed not against him, he touched the hollow of his thigh; and the hollow of Jacob's thigh was strained, as he wrestled with him.

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.
