Jacob wrestles all night with a messenger of God. Jacob’s name is changed to Israel. He sees God face to face.
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 out of joint, 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 as a prince hast thou power 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 I have seen God face to face, and my life is preserved.
31 And as he passed over Penuel the sun rose upon him, and he halted upon his thigh.
32 Therefore the children of Israel eat not of the sinew which shrank, which is upon the hollow of the thigh, unto this day: because he touched the hollow of Jacob’s thigh in the sinew that shrank.
Elder Orson Pratt said:
“[Jacob] was a man of such powerful faith, and his heart so pure before God, that he could take hold of one of them [an angel] and wrestle all night with him, the same as people wrestle in the streets here, only they did not swear; and, I presume, they had not been drinking whiskey; and they wrestled with all their might. I do not suppose the angel, at first, exercised any peculiar faith, but merely a physical strength. He was unable to throw Jacob; and Jacob, like a prince, prevailed with God; but he began to mistrust that he was something more than a man that was wrestling with him, and began to inquire after his name; and by-and-by the angel, determined not to be worsted, put forth one of his fingers, and touched one of Jacob’s sinews, and down he came [see Gen. 32:24–32]. Did this angel inform Jacob that he was a wretched polygamist—an offscouring of the earth, not worthy to dwell in the society of men? No. He was recommended as a great prince, and one that had power to prevail with an angel all night, until the angel put forth his miraculous power on him.”
