25 Oh, absolve me of my sin! Take my hand and lead me to the altar so I can worship God!" 26 But Samuel refused: "No, I can't come alongside you in this. You rejected God's command. Now God has rejected you as king over Israel." 27 As Samuel turned to leave, Saul grabbed at his priestly robe and a piece tore off. 28 Samuel said, "God has just now torn the kingdom from you, and handed it over to your neighbor, a better man than you are. 29 Israel's God-of-Glory doesn't deceive and he doesn't dither. He says what he means and means what he says." 30 Saul tried again, "I have sinned. But don't abandon me! Support me with your presence before the leaders and the people. Come alongside me as I go back to worship God." 31 Samuel did. He went back with him. And Saul went to his knees before God and worshiped.
32 Then Samuel said, "Present King Agag of Amalek to me." Agag came, dragging his feet, muttering that he'd be better off dead. 33 Samuel said, "Just as your sword made many a woman childless, so your mother will be childless among those women!" And Samuel cut Agag down in the presence of God right there in Gilgal. 34 Samuel left immediately for Ramah and Saul went home to Gibeah. 35 Samuel never laid eyes on Saul again in this life, although he grieved long and deeply over him. But God was sorry he had ever made Saul king in the first place.

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.
