1 Samuel 15:3

15:3 So go now and strike down the Amalekites. Destroy everything that they have. Don’t spare them. Put them to death – man, woman, child, infant, ox, sheep, camel, and donkey alike.’”

1 Samuel 15:9

15:9 However, Saul and the army spared Agag, along with the best of the flock, the cattle, the fatlings, and the lambs, as well as everything else that was of value. They were not willing to slaughter them. But they did slaughter everything that was despised and worthless.

1 Samuel 15:13-35

15:13 When Samuel came to him, Saul said to him, “May the Lord bless you! I have done what the Lord said.”

15:14 Samuel replied, “If that is the case, then what is this sound of sheep in my ears and the sound of cattle that I hear?” 15:15 Saul said, “They were brought from the Amalekites; the army spared the best of the flocks and cattle to sacrifice to the Lord our God. But everything else we slaughtered.”

15:16 Then Samuel said to Saul, “Wait a minute! Let me tell you what the Lord said to me last night.” Saul said to him, “Tell me.” 15:17 Samuel said, “Is it not true that when you were insignificant in your own eyes, you became head of the tribes of Israel? The Lord chose you as king over Israel. 15:18 The Lord sent you on a campaign saying, ‘Go and exterminate those sinful Amalekites! Fight against them until you have destroyed them.’ 15:19 Why haven’t you obeyed the Lord? Instead you have greedily rushed upon the plunder! You have done what is wrong in the Lord’s estimation.”

15:20 Then Saul said to Samuel, “But I have obeyed the Lord! I went on the campaign the Lord sent me on. I brought back King Agag of the Amalekites after exterminating the Amalekites. 15:21 But the army took from the plunder some of the sheep and cattle – the best of what was to be slaughtered – to sacrifice to the Lord your God in Gilgal.”

15:22 Then Samuel said,

“Does the Lord take pleasure in burnt offerings and sacrifices

as much as he does in obedience?

Certainly, obedience is better than sacrifice;

paying attention is better than the fat of rams.

15:23 For rebellion is like the sin of divination,

and presumption is like the evil of idolatry.

Because you have rejected the word of the Lord,

he has rejected you as king.”

15:24 Then Saul said to Samuel, “I have sinned, for I have disobeyed what the Lord commanded and what you said as well. For I was afraid of the army, and I followed their wishes. 15:25 Now please forgive my sin! Go back with me so I can worship the Lord.”

15:26 Samuel said to Saul, “I will not go back with you, for you have rejected the word of the Lord, and the Lord has rejected you from being king over Israel!”

15:27 When Samuel turned to leave, Saul grabbed the edge of his robe and it tore. 15:28 Samuel said to him, “The Lord has torn the kingdom of Israel from you this day and has given it to one of your colleagues who is better than you! 15:29 The Preeminent One of Israel does not go back on his word or change his mind, for he is not a human being who changes his mind.” 15:30 Saul again replied, “I have sinned. But please honor me before the elders of my people and before Israel. Go back with me so I may worship the Lord your God.” 15:31 So Samuel followed Saul back, and Saul worshiped the Lord.

Samuel Puts Agag to Death

15:32 Then Samuel said, “Bring me King Agag of the Amalekites.” So Agag came to him trembling, thinking to himself, “Surely death is bitter!” 15:33 Samuel said, “Just as your sword left women childless, so your mother will be the most bereaved among women!” Then Samuel hacked Agag to pieces there in Gilgal before the Lord.

15:34 Then Samuel went to Ramah, while Saul went up to his home in Gibeah of Saul. 15:35 Until the day he died Samuel did not see Saul again. Samuel did, however, mourn for Saul, but the Lord regretted that he had made Saul king over Israel.
