25 So now, let my sin have forgiveness, and go back with me to give worship to the Lord. 26 And Samuel said to Saul, I will not go back with you: for you have put away from you the word of the Lord, and the Lord has put you from your place as king over Israel. 27 And when Samuel was turning round to go away, Saul took the skirt of his robe in his hand, and the cloth came away. 28 And Samuel said to him, The Lord has taken away the kingdom of Israel from you this day by force, and has given it to a neighbour of yours who is better than you. 29 And further, the Glory of Israel will not say what is false, and his purpose may not be changed: for he is not a man, whose purpose may be changed. 30 Then he said, Great is my sin: but still, give me honour now before the heads of my people and before Israel, and come back with me so that I may give worship to the Lord your God. 31 So Samuel went back after Saul, and Saul gave worship to the Lord.

32 Then Samuel said, Make Agag, the king of the Amalekites, come here to me. And Agag came to him shaking with fear. And Agag said, Truly the pain of death is past. 33 And Samuel said, As your sword has made women without children, so now your mother will be without children among women. And Agag was cut up by Samuel, bone from bone, before the Lord in Gilgal. 34 Then Samuel went to Ramah; and Saul went up to his house in Gibeah, in the land of Saul. 35 And Samuel never saw Saul again till the day of his death; but Samuel was sorrowing for Saul: and it was no longer the Lord's pleasure for Saul to be king over Israel.

Commentary on 1 Samuel 15:24-31

(Read 1 Samuel 15:24-31)

There were several signs of hypocrisy in Saul's repentance. 1. He besought Samuel only, and seemed most anxious to stand right in his opinion, and to gain his favour. 2. He excuses his fault, even when confessing it; that is never the way of a true penitent. 3. All his care was to save his credit, and preserve his interest in the people. Men are fickle and alter their minds, feeble and cannot effect their purposes; something happens they could not foresee, by which their measures are broken; but with God it is not so. The Strength of Israel will not lie.

Commentary on 1 Samuel 15:32-35

(Read 1 Samuel 15:32-35)

Many think the bitterness of death is past when it is not gone by; they put that evil day far from them, which is very near. Samuel calls Agag to account for his own sins. He followed the example of his ancestors' cruelty, justly therefore is all the righteous blood shed by Amalek required. Saul seems unconcerned at the token of God's displeasure which he lay under, yet Samuel mourns day and night for him. Jerusalem was carnally secure while Christ wept over it. Do we desire to do the whole will of God? Turn to him, not in form and appearance, but with sincerity.
