1 Samuel 15:3-7 New King James Version (NKJV)
3 Now go and attack[a] Amalek, and utterly destroy all that they have, and do not spare them. But kill both man and woman, infant and nursing child, ox and sheep, camel and donkey.’ ”
4 So Saul gathered the people together and numbered them in Telaim, two hundred thousand foot soldiers and ten thousand men of Judah. 5 And Saul came to a city of Amalek, and lay in wait in the valley.
6 Then Saul said to the Kenites, “Go, depart, get 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 attacked the Amalekites, from Havilah all the way to Shur, which is east of Egypt.
