1 Samuel 24:4-10

And the men of David said unto him, Behold, the day of which Jehovah said unto thee, Behold, I will deliver thine enemy into thy hand, and thou shalt do to him as it shall seem good unto thee. Then David arose, and cut off the skirt of Saul’s robe privily. And it came to pass afterward, that David’s heart smote him, because he had cut off Saul’s skirt. And he said unto his men, Jehovah forbid that I should do this thing unto my lord, Jehovah’s anointed, to put forth my hand against him, seeing he is Jehovah’s anointed. So David checked his men with these words, and suffered them not to rise against Saul. And Saul rose up out of the cave, and went on his way. David also arose afterward, and went out of the cave, and cried after Saul, saying, My lord the king. And when Saul looked behind him, David bowed with his face to the earth, and did obeisance. And David said to Saul, Wherefore hearkenest thou to men’s words, saying, Behold, David seeketh thy hurt? Behold, this day thine eyes have seen how that Jehovah had delivered thee to-day into my hand in the cave: and some bade me kill thee; but mine eye spared thee; and I said, I will not put forth my hand against my lord; for he is Jehovah’s anointed.
