1 Samuel 15:2-9

2This is what the Lord Almighty says: ‘I will punish the Amalekites for what they did to Israel when they waylaid them as they came up from Egypt.

3Now go, attack the Amalekites and totally destroy all that belongs to them. Do not spare them; put to death men and women, children and infants, cattle and sheep, camels and donkeys.’ ”

4So Saul summoned the men and mustered them at Telaim—two hundred thousand foot soldiers and ten thousand from Judah.

5Saul went to the city of Amalek and set an ambush in the ravine.

6Then he said to the Kenites, “Go away, leave the Amalekites so that I do not destroy you along with them; for you showed kindness to all the Israelites when they came up out of Egypt.” So the Kenites moved away from the Amalekites.

7Then Saul attacked the Amalekites all the way from Havilah to Shur, near the eastern border of Egypt.

8He took Agag king of the Amalekites alive, and all his people he totally destroyed with the sword.

9But Saul and the army spared Agag and the best of the sheep and cattle, the fat calves and lambs—everything that was good. These they were unwilling to destroy completely, but everything that was despised and weak they totally destroyed.
