1 Samuel 15:1-6

King James Version

15 Samuel also said unto Saul, The Lord sent me to anoint thee to be king over his people, over Israel: now therefore hearken thou unto the voice of the words of the Lord.

² Thus saith 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 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.

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 ye shewed kindness to all the children of Israel, when they came up out of Egypt. So the Kenites departed from among the Amalekites.
