1 Samuel 24:8-11

David arose afterward and went out from the cave. And he called after Saul saying, “My lord the king!” And when Saul looked behind him, David had bowed down with his face to the ground and paid homage. David said to Saul, “Why do you listen to the words of men saying, ‘David seeks your harm’? This day you have seen with your own eyes that the LORD delivered you today into my hand in the cave. So that some said to kill you, but my eye had compassion on you. And I said, ‘I will not put forth my hand against my lord, for he is anointed of the LORD.’ See, my father! Look at the corner of your robe in my hand. Indeed, I cut off the corner of your robe, but I did not kill you. Observe and see that there is no evil or rebellion in my hand. I have not sinned against you, but you are lying in wait for my life to take it.
