1st Samuel Chapter 15 American Standard-ASV1901
And Saul said unto the Kenites, Go, depart, get you down from among the Amalekites, lest I destroy you with them; for ye showed kindness to all the children of Israel, when they came up out of Egypt. So the Kenites departed from among the Amalekites.
But Saul and the people spared Agag, and the best of the sheep, and of the oxen, and of the fatlings, and the lambs, and all that was good, and would not utterly destroy them: but everything that was vile and refuse, that they destroyed utterly.
It repenteth me that I have set up Saul to be king; for he is turned back from following me, and hath not performed my commandments. And Samuel was wroth; and he cried unto Jehovah all night.
And Samuel rose early to meet Saul in the morning; and it was told Samuel, saying, Saul came to Carmel, and, behold, he set him up a monument, and turned, and passed on, and went down to Gilgal.
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.
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.
And Samuel said, Hath Jehovah as great delight in burnt-offerings and sacrifices, as in obeying the voice of Jehovah? Behold, to obey is better than sacrifice, and to hearken than the fat of rams.
