1 Samuel 15:13-15

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.”

1 Samuel 15:20-21

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.”
