1 Samuel 15:8-10

The Voice

⁸ He cut down the entire population with the sword, as God had told him to do, except he captured King Agag of the Amalekites and kept him alive. ⁹ Saul and the army spared Agag, and they saved the best of the livestock: the sheep, the oxen, the lambs, and the best of all the stock. They kept what was valuable instead of destroying it, and they only destroyed those things they considered worthless.

¹⁰ Then Samuel heard the voice of the Eternal.
