1 Samuel 15:3–9

³Now go and smite Amalek, and destroy utterly all that they have, and spare them not, but slay both man and woman, infant and suckling, ox and sheep, camel and ass. ⁴And Saul summoned the people, and numbered them in Telaim, two hundred thousand footmen, and ten thousand men of Judah. ⁵And Saul came to the city of the Amalekites, and set an ambush in the valley. ⁶And Saul said to the Kenites, Go, depart, and go down from among the Amalekites, lest I destroy you with them; for ye shewed kindness to all the children of Israel when they came up out of Egypt. And the Kenites departed from among the Amalekites. ⁷And Saul smote Amalek from Havilah as thou comest to Shur, which is opposite to Egypt. ⁸And he took Agag the king of Amalek alive, and utterly destroyed all the people with the edge of the sword. ⁹And Saul and the people spared Agag, and the best of the sheep and oxen, and beasts of the second bearing, and the lambs, and all that was good, and would not devote them to destruction; but everything that was mean and weak, that they destroyed utterly.
