1 Samuel 15:1-7

The LORD Rejects Saul as King 1Samuel said to Saul, “I am the one the LORD sent to anoint you king over his people Israel; so listen now to the message from the LORD . 2This is what the LORD Almighty says: ‘I will punish the Amalekites for what they did to Israel when they waylaid them as they came up from Egypt.

3Now go, attack the Amalekites and totally destroy The Hebrew term refers to the irrevocable giving over of things or persons to the Lord, often by totally destroying them; also in verses 8, 9, 15, 18, 20 and 21. all that belongs to them. Do not spare them; put to death men and women, children and infants, cattle and sheep, camels and donkeys.’ ” 4So Saul summoned the men and mustered them at Telaim—two hundred thousand foot soldiers and ten thousand from Judah. 5Saul went to the city of Amalek and set an ambush in the ravine.

6Then he said to the Kenites, “Go away, leave the Amalekites so that I do not destroy you along with them; for you showed kindness to all the Israelites when they came up out of Egypt.” So the Kenites moved away from the Amalekites. 7Then Saul attacked the Amalekites all the way from Havilah to Shur, near the eastern border of Egypt.
