1 Samuel 24:6-8

Amplified Bible

⁶ He said to his men, “The Lord forbid that I should do this thing to my master, the Lord’s anointed, to put out my hand against him, since he is the anointed of the Lord.” ⁷ So David strongly rebuked his men with these words and did not let them rise up against Saul. Saul got up, left the cave and went on his way.

⁸ 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.
