I Samuel 15:20

20 "But I did obey the Lord," Saul said. "I went on the mission the Lord assigned me. I completely destroyed the Amalekites and brought back Agag their king.

20 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.
