When he gets ready to go to sleep, take careful notice of the place where he lies down. Then go, uncover his legs, and lie down beside him. He will tell you what you should do."

Who can uncover its outer covering? Who can penetrate to the inside of its armor?

But I will strip everything away from Esau's descendants. I will uncover their hiding places so they cannot hide. Their children, relatives, and neighbors will all be destroyed. Not one of them will be left!
