1 Samuel 24:4-8

Then David’s men said to him, “Behold, this is the day of which the Lord said to you, ‘Behold; I am about to hand your enemy over to you, and you shall do to him as it seems good to you.’ ” Then David got up and cut off the edge of Saul’s robe secretly.

But it came about afterward that David’s conscience bothered him because he had cut off the edge of Saul’s robe.

So he said to his men, “Far be it from me because of the Lord that I would do this thing to my lord, the Lord’s anointed, to reach out with my hand against him, since he is the Lord’s anointed.”

And David rebuked his men with these words and did not allow them to rise up against Saul. And Saul got up, left the cave, and went on his way.

Afterward, however, David got up 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 prostrated himself.
