1 Samuel 15:9; 1 Samuel 15:21

9 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.

21 "But the people took some of the spoil, sheep and oxen, the choicest of the things devoted to destruction, to sacrifice to the LORD your God at Gilgal."
