1 Samuel 15:7-9

Then Saul slaughtered the Amalekites from Havilah all the way to Shur, east of Egypt. He captured Agag, the Amalekite king, but completely destroyed everyone else. Saul and his men spared Agag’s life and kept the best of the sheep and goats, the cattle, the fat calves, and the lambs—everything, in fact, that appealed to them. They destroyed only what was worthless or of poor quality.
