Genesis 32
24 Ref Then Jacob was by himself; and a man was fighting with him till dawn.
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.
