1 Samuel 24:4-7

MLV(i) 4 And the men of David said to him, Behold, the day of which Jehovah said to you, Behold, I will deliver your enemy into your hand and you will do to him as it will seem good to you. Then David arose and cut off the skirt of Saul's robe secretly.
5 And it happened afterward, that David's heart killed* him, because he had cut off Saul's skirt. 6 And he said to his men, Jehovah forbid that I should do this thing to my lord, Jehovah's anointed, to put forth my hand against him, since he is Jehovah's anointed. 7 So David restrained his men with these words and did not allow them to rise against Saul. And Saul rose up out of the cave and went on his way.
