1 Samuel 24:5-8
24:5 Afterward David’s conscience bothered him because he had cut off an edge of Saul’s robe.
24:6 He said to his men, “May the Lord keep me far away from doing such a thing to my lord, who is the Lord’s chosen one, by extending my hand against him. After all, he is the Lord’s chosen one.”
24:7 David restrained his men with these words and did not allow them to rise up against Saul. Then Saul left the cave and started down the road.
24:8 Afterward David got up and went out of the cave. He called out after Saul, “My lord, O king!” When Saul looked behind him, David kneeled down and bowed with his face to the ground.
