1 Samuel 24:4-7

4 Then the men of David said to him, “This is the day of which the Lord said to you, ‘Behold, I will deliver your enemy into your hand, that you may do to him as it seems good to you.’ ” And David arose and secretly cut off a corner of Saul’s robe. 5 Now it happened afterward that David’s heart troubled him because he had cut Saul’s robe. 6 And he said to his men, “The Lord forbid that I should do this thing to my master, the Lord’s anointed, to stretch out my hand against him, seeing he is the anointed of the Lord.” 7 So David restrained his servants with these words, and did not allow them to rise against Saul. And Saul got up from the cave and went on his way.
