10 Then the Lord said to Samuel, 11 "I am sorry that I ever made Saul king, for he has not been loyal to me and has refused to obey my command." Samuel was so deeply moved when he heard this that he cried out to the Lord all night. 12 Early the next morning Samuel went to find Saul. Someone told him, "Saul went to the town of Carmel to set up a monument to himself; then he went on to Gilgal." 13 When Samuel finally found him, Saul greeted him cheerfully. "May the Lord bless you," he said. "I have carried out the Lord 's command!" 14 "Then what is all the bleating of sheep and goats and the lowing of cattle I hear?" Samuel demanded. 15 "It's true that the army spared the best of the sheep, goats, and cattle," Saul admitted. "But they are going to sacrifice them to the Lord your God. We have destroyed everything else." 16 Then Samuel said to Saul, "Stop! Listen to what the Lord told me last night!" "What did he tell you?" Saul asked. 17 And Samuel told him, "Although you may think little of yourself, are you not the leader of the tribes of Israel? The Lord has anointed you king of Israel. 18 And the Lord sent you on a mission and told you, 'Go and completely destroy the sinners, the Amalekites, until they are all dead.' 19 Why haven't you obeyed the Lord ? Why did you rush for the plunder and do what was evil in the Lord 's sight?" 20 "But I did obey the Lord," Saul insisted. "I carried out the mission he gave me. I brought back King Agag, but I destroyed everyone else. 21 Then my troops brought in the best of the sheep, goats, cattle, and plunder to sacrifice to the Lord your God in Gilgal." 22 But Samuel replied, "What is more pleasing to the Lord : your burnt offerings and sacrifices or your obedience to his voice? Listen! Obedience is better than sacrifice, and submission is better than offering the fat of rams. 23 Rebellion is as sinful as witchcraft, and stubbornness as bad as worshiping idols. So because you have rejected the command of the Lord, he has rejected you as king."

24 Then Saul admitted to Samuel, "Yes, I have sinned. I have disobeyed your instructions and the Lord 's command, for I was afraid of the people and did what they demanded. 25 But now, please forgive my sin and come back with me so that I may worship the Lord ." 26 But Samuel replied, "I will not go back with you! Since you have rejected the Lord 's command, he has rejected you as king of Israel." 27 As Samuel turned to go, Saul tried to hold him back and tore the hem of his robe. 28 And Samuel said to him, "The Lord has torn the kingdom of Israel from you today and has given it to someone else-one who is better than you. 29 And he who is the Glory of Israel will not lie, nor will he change his mind, for he is not human that he should change his mind!" 30 Then Saul pleaded again, "I know I have sinned. But please, at least honor me before the elders of my people and before Israel by coming back with me so that I may worship the Lord your God." 31 So Samuel finally agreed and went back with him, and Saul worshiped the Lord .

32 Then Samuel said, "Bring King Agag to me." Agag arrived full of hope, for he thought, "Surely the worst is over, and I have been spared!" 33 But Samuel said, "As your sword has killed the sons of many mothers, now your mother will be childless." And Samuel cut Agag to pieces before the Lord at Gilgal. 34 Then Samuel went home to Ramah, and Saul returned to his house at Gibeah of Saul. 35 Samuel never went to meet with Saul again, but he mourned constantly for him. And the Lord was sorry he had ever made Saul king of Israel.

Commentary on 1 Samuel 15:10-23

(Read 1 Samuel 15:10-23)

Repentance in God is not a change of mind, as it is in us, but a change of method. The change was in Saul; "He is turned back from following me." Hereby he made God his enemy. Samuel spent a whole night in pleading for Saul. The rejection of sinners is the grief of believers: God delights not in their death, nor should we. Saul boasts to Samuel of his obedience. Thus sinners think, by justifying themselves, to escape being judged of the Lord. The noise the cattle made, like the rust of the silver, James 5:3, witnessed against him. Many boast of obedience to the command of God; but what means then their indulgence of the flesh, their love of the world, their angry and unkind spirit, and their neglect of holy duties, which witness against them? See of what evil covetousness is the root; and see what is the sinfulness of sin, and notice that in it which above any thing else makes it evil in the sight of the Lord; it is disobedience: "Thou didst not obey the voice of the Lord." Carnal, deceitful hearts, like Saul, think to excuse themselves from God's commandments by what pleases themselves. It is hard to convince the children of disobedience. But humble, sincere, and conscientious obedience to the will of God, is more pleasing and acceptable to him than all burnt-offering and sacrifices. God is more glorified and self more denied, by obedience than by sacrifice. It is much easier to bring a bullock or lamb to be burned upon the altar, than to bring every high thought into obedience to God, and to make our will subject to his will. Those are unfit and unworthy to rule over men, who are not willing that God should rule over them.

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.
