1 Samuel 15:17-31

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. And the LORD sent you on a mission and told you, ‘Go and completely destroy the sinners, the Amalekites, until they are all dead.’ Why haven’t you obeyed the LORD? Why did you rush for the plunder and do what was evil in the LORD’s sight?” “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. Then my troops brought in the best of the sheep, goats, cattle, and plunder to sacrifice to the LORD your God in Gilgal.” 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. 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.” 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. But now, please forgive my sin and come back with me so that I may worship the LORD.” 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.” As Samuel turned to go, Saul tried to hold him back and tore the hem of his robe. 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. 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!” 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.” So Samuel finally agreed and went back with him, and Saul worshiped the LORD.
