Jacob sent large herds of livestock ahead as gifts for his brother Esau in hopes of appeasing him, as he was afraid Esau would attack him. That night after sending his family across the river, Jacob wrestled alone with a man until daybreak. Though the man injured Jacob's hip, Jacob refused to let him go until he received a blessing. The man then changed Jacob's name to Israel, saying he had struggled with God and men and overcome. Jacob named the place Peniel, for he said he saw God face to face yet his life was spared.
