1 Samuel 15:19-21

Wherefore then didst thou not obey the voice of Jehovah, but didst fly upon the spoil, and didst that which was evil in the sight of Jehovah? And Saul said unto Samuel, Yea, I have obeyed the voice of Jehovah, and have gone the way which Jehovah sent me, and have brought Agag the king of Amalek, and have utterly destroyed the Amalekites. But the people took of the spoil, sheep and oxen, the chief of the devoted things, to sacrifice unto Jehovah thy God in Gilgal.
