1 Samuel 15:16-19

Samuel said to Saul, “Stop! Let me tell you what the LORD said to me last night.” Saul answered, “Tell me.” Samuel said, “Once you didn’t think much of yourself, but now you have become the leader of the tribes of Israel. The LORD appointed you to be king over Israel. And he sent you on a mission. He said, ‘Go and destroy those evil people, the Amalekites. Make war on them until all of them are dead.’ Why didn’t you obey the LORD? Why did you take the best things? Why did you do what the LORD said was wrong?”
