1 Samuel 15:3-9

3Now go and strike down Amalek and put all he has under the ban of destruction—so have no pity on him; but kill both men and women, children and nursing infants, oxen and sheep, camels and donkeys.’”

4So Saul summoned the troops and numbered them in Telaim: 200,000 foot soldiers and 10,000 men of Judah.

5Saul advanced to the city of Amalek and lay in wait in the valley.

6Then Saul said to the Kenites, “Go, depart, get down from among the Amalekites, or else I may destroy you with them—for you showed kindness to all Bnei-Yisrael when they came up from Egypt.” So the Kenites withdrew from among the Amalekites.

7Then Saul struck down the Amalekites from Havilah until you come to Shur, which is close to Egypt.

8He captured King Agag of Amalek alive, and utterly destroyed all the people with the edge of the sword.

9But Saul and the people spared Agag as well as the best of the sheep, the cattle, even the fatlings and the lambs, and all that was good, since they were not willing to utterly destroy them; everything that was worthless and feeble, they destroyed completely.
