12 And see, my father, see the skirt of your robe in my hand: for the fact that I took off the skirt of your robe and did not put you to death is witness that I have no evil purpose, and I have done you no wrong, though you are waiting for my life to take it. 13 May the Lord be judge between me and you, and may the Lord give me my rights against you, but my hand will never be lifted up against you.

Matthew Henry's Commentary on 1 Samuel 24:12-13

Commentary on 1 Samuel 24:8-15

(Read 1 Samuel 24:8-15)

David was falsely charged with seeking Saul's hurt; he shows Saul that God's providence had given him opportunity to do it. And it was upon a good principle that he refused to do it. He declares his fixed resolution never to be his own avenger. If men wrong us, God will right us, at farthest, in the judgment of the great day.
