1Sam 15:8-9

8 He took King Agag of the Amalekites alive, but utterly destroyed all the people with the edge of the sword. 9 Saul and the people spared Agag, and the best of the sheep and of the cattle and of the fatlings, and the lambs, and all that was valuable, and would not utterly destroy them; all that was despised and worthless they utterly destroyed.
