1 Samuel 15:14

10Then the LORD’s word came to Samuel, saying,

11“It grieves me that I have set up Saul to be king, for he has turned back from following me, and has not performed my commandments.” Samuel was angry; and he cried to the LORD all night.

12Samuel rose early to meet Saul in the morning; and Samuel was told, saying, “Saul came to Carmel, and behold, he set up a monument for himself, turned, passed on, and went down to Gilgal.”

13Samuel came to Saul; and Saul said to him, “You are blessed by the LORD! I have performed the commandment of the LORD.”

14Samuel said, “Then what does this bleating of the sheep in my ears and the lowing of the cattle which I hear mean?”

15Saul said, “They have brought them from the Amalekites; for the people spared the best of the sheep and of the cattle, to sacrifice to the LORD your God. We have utterly destroyed the rest.”

16Then Samuel said to Saul, “Stay, and I will tell you what the LORD said to me last night.” He said to him, “Say on.”

17Samuel said, “Though you were little in your own sight, weren’t you made the head of the tribes of Israel? The LORD anointed you king over Israel;

18and the LORD sent you on a journey, and said, ‘Go, and utterly destroy the sinners the Amalekites, and fight against them until they are consumed.’
