1 Samuel 15:1-9 - Israel Defeats The Amalekites
1 Samuel also said unto Saul, The LORD sent me to anoint you to be king over his people, over Israel: now therefore hearken you unto the voice of the words of the LORD. 2 Thus says the LORD of hosts, I remember that which Amalek did to Israel, how he laid wait for him in the way, when he came up from Egypt. 3 Now go and strike Amalek, and utterly destroy all that they have, and spare them not; but slay both man and woman, infant and nursing child, ox and sheep, camel and donkey.
4 And Saul gathered the people together, and numbered them in Telaim, two hundred thousand footmen, and ten thousand men of Judah. 5 And Saul came to a city of Amalek, and laid wait in the valley. 6 And Saul said unto the Kenites, Go, depart, get you down from among the Amalekites, lest I destroy you with them: for you showed kindness to all the children of Israel, when they came up out of Egypt. So the Kenites departed from among the Amalekites.
7 And Saul struck down the Amalekites from Havilah until you come to Shur, that is east of Egypt. 8 And he took Agag the king of the Amalekites alive, and utterly destroyed all the people with the edge of the sword. 9 But Saul and the people spared Agag, and the best of the sheep, and of the oxen, and of the fatlings, and the lambs, and all that was good, and would not utterly destroy them: but everything that was despised and worthless, that they destroyed utterly.
