1 Samuel 15:2-4

Thus saith Jehovah of hosts, I have marked that which Amalek did to Israel, how he set himself against him in the way, when he came up out of Egypt. Now go and smite Amalek, and utterly destroy all that they have, and spare them not; but slay both man and woman, infant and suckling, ox and sheep, camel and ass. And Saul summoned the people, and numbered them in Telaim, two hundred thousand footmen, and ten thousand men of Judah.
