1 Samuel 15:17-20

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.
