1 Samuel 15:22-29

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. 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.” 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. Now I beg you, forgive my sin and come back with me, so that I may worship the LORD.” But Samuel said to him, “I will not go back with you. You have rejected the word of the LORD, and the LORD has rejected you as king over Israel!” As Samuel turned to leave, Saul caught hold of the hem of his robe, and it tore. Samuel said to him, “The LORD has torn the kingdom of Israel from you today and has given it to one of your neighbors—to one better than you. He who is the Glory of Israel does not lie or change his mind; for he is not a human being, that he should change his mind.”
