Saul said to Samuel, Yes, I have obeyed the voice of Yahweh, and have gone the way which Yahweh sent me, and have brought Agag the king of Amalek, and have utterly destroyed the Amalekites.
For the Lord said, I remember the Amaleks that when you were trying to come into the land, they withstood you. And therefore God wants you to go down and utterly wipe out the Amaleks; every man, woman, child, animal. [Don't take anything back alive, utterly slay everything] ( 1 Samuel 15:2-3 ).
