1 Samuel 15:10-17

The word of the LORD came to Samuel: “I regret that I have made Saul king, for he has turned back from following me and has not performed my commandments.” And Samuel was angry, and he cried to the LORD all night. And Samuel rose early to meet Saul in the morning. And it was told Samuel, “Saul came to Carmel, and behold, he set up a monument for himself and turned and passed on and went down to Gilgal.” And Samuel came to Saul, and Saul said to him, “Blessed be you to the LORD. I have performed the commandment of the LORD.” And Samuel said, “What then is this bleating of the sheep in my ears and the lowing of the oxen that I hear?” Saul said, “They have brought them from the Amalekites, for the people spared the best of the sheep and of the oxen to sacrifice to the LORD your God, and the rest we have devoted to destruction.” Then Samuel said to Saul, “Stop! I will tell you what the LORD said to me this night.” And he said to him, “Speak.” And Samuel said, “Though you are little in your own eyes, are you not the head of the tribes of Israel? The LORD anointed you king over Israel.
