1 Samuel 15:2-9

2Thus says the Lord of hosts, ‘I will 1punish Amalek 2for what he did to Israel, how he set himself against him on the way while he was coming up from Egypt. 3Now go and strike Amalek and 3utterly destroy all that he has, and do not spare him; but 4put to death both man and woman, child and infant, ox and sheep, camel and donkey.’”

4Then Saul summoned the people and 5numbered them in 6Telaim, 200,000 foot soldiers and 10,000 men of Judah. 5Saul came to the city of Amalek and set an ambush in the valley. 6Saul said to 7the Kenites, “Go, depart, go down from among the Amalekites, so that I do not destroy you with them; for 8you showed kindness to all the sons of Israel when they came up from Egypt.” So the Kenites departed from among the Amalekites. 7So 9Saul 10defeated the Amalekites, from 11Havilah as you go to 12Shur, which is 13east of Egypt. 8He captured 14Agag the king of the Amalekites alive, and 15utterly destroyed all the people with the edge of the sword. 9But Saul and the people 16spared 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.
