25 Now therefore, I pray thee, pardon my sin, and turn again with me, that I may worship Jehovah. 26 And Samuel said unto Saul, I will not return with thee; for thou hast rejected the word of Jehovah, and Jehovah hath rejected thee from being king over Israel. 27 And as Samuel turned about to go away, [Saul] laid hold upon the skirt of his robe, and it rent. 28 And Samuel said unto him, Jehovah hath rent the kingdom of Israel from thee this day, and hath given it to a neighbor of thine, that is better than thou. 29 And also the Strength of Israel will not lie nor repent; for he is not a man, that he should repent. 30 Then he said, I have sinned: yet honor me now, I pray thee, before the elders of my people, and before Israel, and turn again with me, that I may worship Jehovah thy God. 31 So Samuel turned again after Saul; and Saul worshipped Jehovah.

32 Then said Samuel, Bring ye hither to me Agag the king of the Amalekites. And Agag came unto him cheerfully. And Agag said, Surely the bitterness of death is past. 33 And Samuel said, As thy sword hath made women childless, so shall thy mother be childless among women. And Samuel hewed Agag in pieces before Jehovah in Gilgal. 34 Then Samuel went to Ramah; and Saul went up to his house to Gibeah of Saul. 35 And Samuel came no more to see Saul until the day of his death; for Samuel mourned for Saul: and Jehovah repented that he had made Saul 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.
