1 Samuel 24:8-11

Then David also got up afterward and went out of the cave and called after Saul, saying, “My lord the king!” And when Saul looked behind him, David bowed with his face to the ground and lay himself face down. David said to Saul, “Why do you listen to the words of men who say, ‘David seeks to harm you?’ Behold, your eyes have seen today how the LORD had given you into my hand in the cave. Some told me to kill you, but I spared you; I said, ‘I will not reach out my hand against my lord, for he is the LORD’S anointed.’ Look, my father! Indeed, see the hem of your robe in my hand! Since I cut off the hem of your robe and did not kill you, know and understand [without question] that there is no evil or treason in my hands. I have not sinned against you, though you are lying in wait to take my life.
