1 Samuel 15:7 WEB

⁵  Saul came to the city of Amalek, and laid wait in the valley.

⁶  Saul said to the Kenites, Go, depart, get you down from among the Amalekites, lest I destroy you with them; for you shown kindness to all the children of Israel, when they came up out of Egypt. So the Kenites departed from among the Amalekites.

⁷  Saul struck the Amalekites, from Havilah as you go to Shur, that is before Egypt.

⁸  He took Agag the king of the Amalekites alive, and utterly destroyed all the people with the edge of the sword.

⁹  But Saul and the people spared Agag, and the best of the sheep, and of the oxen, and of the fatlings, and the lambs, and all that was good, and wouldn't utterly destroy them: but everything that was vile and refuse, that they destroyed utterly.
