1 Samuel 15:15-16

And Saul said, They have brought them from the Amalekites: for the people spared the best of the sheep and of the oxen, to sacrifice unto Jehovah thy God; and the rest we have utterly destroyed. Then Samuel said unto Saul, Stay, and I will tell thee what Jehovah hath said to me this night. And he said unto him, Say on.
