1 Samuel 15:19-21

Young's Literal Translation

¹⁹ and why hast thou not hearkened to the voice of Jehovah -- and dost fly unto the spoil, and dost do the evil thing in the eyes of Jehovah?'

²⁰ And Saul saith unto Samuel, `Because -- I have hearkened to the voice of Jehovah, and I go in the way which Jehovah hath sent me, and bring in Agag king of Amalek, and Amalek I have devoted;

²¹ and the people taketh of the spoil of the flock and herd, the first part of the devoted thing, for sacrifice to Jehovah thy God in Gilgal.'
