1 Samuel 15:16 WEB

¹⁴  Samuel said, What means then this bleating of the sheep in my ears, and the lowing of the oxen which I hear?

¹⁵  Saul said, They have brought them from the Amalekites: for the people spared the best of the sheep and of the oxen, to sacrifice to Yahweh your God; and the rest we have utterly destroyed.

¹⁶  Then Samuel said to Saul, Stay, and I will tell you what Yahweh has said to me this night. He said to him, Say on.

¹⁷  Samuel said, 'Though you were little in your own sight, weren't you made the head of the tribes of Israel? Yahweh anointed you king over Israel;

¹⁸  and Yahweh sent you on a journey, and said, 'Go, and utterly destroy the sinners the Amalekites, and fight against them until they are consumed.'
