A Wolf, having stolen a lamb from a fold, was carrying him off to his lair. A Lion met him in the path, and, seizing the lamb, took it from him. The Wolf, standing at a safe distance, exclaimed: “You have unrighteously taken from me that which was mine.” The Lion jeeringly replied: “It was righteously yours, eh? Was it the gift of a friend, or did you get it by purchase? If you did not get it in one way or the other, how then did you come by it?”
One thief is no better than another.
