1 Samuel 15:18-20

Amplified Bible

¹⁸ and the Lord sent you on a mission, and said, ‘Go, totally destroy the sinners, the Amalekites, and fight against them until they are eliminated.’ ¹⁹ Why did you not obey the voice of the Lord, but [instead] swooped down on the plunder [with shouts of victory] and did evil in the sight of the Lord?”

²⁰ Saul said to Samuel, “I have obeyed the voice of the Lord, and have gone on the mission on which the Lord sent me, and have brought back Agag the king of Amalek, and have completely destroyed the Amalekites.
