Genesis 32
25 Ref But when the man saw that he was not able to overcome Jacob, he gave him a blow in the hollow part of his leg, so that his leg was damaged.
26 Ref And he said to him, Let me go now, for the dawn is near. But Jacob said, I will not let you go till you have given me your blessing.
27 Then he said, What is your name? And he said, Jacob.
28 Ref And he said, Your name will no longer be Jacob, but Israel: for in your fight with God and with men you have overcome.
