1 Samuel 15:18-19

English Standard Version

¹⁸ And the Lord sent you on a mission and said, ‘Go, devote to destruction the sinners, the Amalekites, and fight against them until they are consumed.’ ¹⁹ Why then did you not obey the voice of the Lord? ^(A)Why did you pounce on the spoil and do what was evil in the sight of the Lord?”
