19 Why did you not obey the Lord? Why did you pounce on the plunder and do evil in the eyes of the Lord?" 20 "But I did obey the Lord," Saul said. "I went on the mission the Lord assigned me. I completely destroyed the Amalekites and brought back Agag their king. 21 The soldiers took sheep and cattle from the plunder, the best of what was devoted to God, in order to sacrifice them to the Lord your God at Gilgal." 22 But Samuel replied: "Does the Lord delight in burnt offerings and sacrifices as much as in obeying the Lord? To obey is better than sacrifice, and to heed is better than the fat of rams. 23 For rebellion is like the sin of divination, and arrogance like the evil of idolatry. Because you have rejected the word of the Lord, he has rejected you as king."

24 Then Saul said to Samuel, "I have sinned. I violated the Lord's command and your instructions. I was afraid of the men and so I gave in to them.

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.
