1 Samuel 24:4-14
4 The men said, "This is the day the LORD spoke of when he said to you, 'I will give your enemy into your hands for you to deal with as you wish.' " Then David crept up unnoticed and cut off a corner of Saul's robe. 5 Afterward, David was conscience-stricken for having cut off a corner of his robe. 6 He said to his men, "The LORD forbid that I should do such a thing to my master, the LORD's anointed, or lift my hand against him; for he is the anointed of the LORD." 7 With these words David rebuked his men and did not allow them to attack Saul. And Saul left the cave and went his way. 8 Then David went out of the cave and called out to Saul, "My lord the king!" When Saul looked behind him, David bowed down and prostrated himself with his face to the ground. 9 He said to Saul, "Why do you listen when men say, 'David is bent on harming you'? 10 This day you have seen with your own eyes how the LORD delivered you into my hands in the cave. Some urged me to kill you, but I spared you; I said, 'I will not lift my hand against my master, because he is the LORD's anointed.' 11 See, my father, look at this piece of your robe in my hand! I cut off the corner of your robe but did not kill you. Now understand and recognize that I am not guilty of wrongdoing or rebellion. I have not wronged you, but you are hunting me down to take my life. 12 May the LORD judge between you and me. And may the LORD avenge the wrongs you have done to me, but my hand will not touch you. 13 As the old saying goes, 'From evildoers come evil deeds,' so my hand will not touch you. 14 "Against whom has the king of Israel come out? Whom are you pursuing? A dead dog? A flea?
What are we going to do if we get the chance to retaliate against our enemies? This reading is a good example why we should not. We are not master of others one life... Let God deal with it...
