Genesis 32:23-33
23And having delivered over all the things that belonged to him, 24he remained alone. And behold, a man wrestled with him until morning. 25And when he saw that he would not be able to overcome him, he touched the nerve of his thigh, and immediately it withered. 26And he said to him, “Release me, for now the dawn ascends.” He responded, “I will not release you, unless you bless me.” 27Therefore he said, “What is your name?” He answered, “Jacob.” 28But he said, “Your name will not be called Jacob, but Israel; for if you have been strong against God, how much more will you prevail against men?” 29Jacob questioned him, “Tell me, by what name are you called?” He responded, “Why do you ask my name?” And he blessed him in the same place. 30And Jacob called the name of the place Peniel, saying, “I have seen God face to face, and my soul has been saved.” 31And immediately the sun rose upon him, after he had crossed beyond Peniel. Yet in truth, he limped on his foot. 32For this reason, the sons of Israel, even to the present day, do not eat the nerve that withered in Jacob’s thigh, because he touched the nerve of his thigh and it was obstructed.
