1 Samuel 15:7-9

So Saul defeated the Amalekites, from Havilah as you go to Shur, which is east of Egypt. He captured Agag the king of the Amalekites alive, and utterly destroyed all the people with the edge of the sword. But Saul and the people spared Agag and the best of the sheep, the oxen, the fatlings, the lambs, and all that was good, and were not willing to destroy them utterly; but everything despised and worthless, that they utterly destroyed.
