1 Samuel 15:13-15

13When Samuel reached him, Saul said, “The Lord bless you! I have carried out the Lord’s instructions.” 14But Samuel said, “What then is this bleating of sheep in my ears? What is this lowing of cattle that I hear?” 15Saul answered, “The soldiers brought them from the Amalekites; they spared the best of the sheep and cattle to sacrifice to the Lord your God, but we totally destroyed the rest.”
