1 Samuel 24:17-19

17“You are more righteous than I,” he said. “You have treated me well, but I have treated you badly. 18You have just now told me about the good you did to me; the LORD delivered me into your hands, but you did not kill me. 19When a man finds his enemy, does he let him get away unharmed? May the LORD reward you well for the way you treated me today.
