1 Samuel 15:4-6

So Saul called the army together at Telaim. There were two hundred thousand foot soldiers and ten thousand men from Judah. Then Saul went to the city of Amalek and set up an ambush in the ravine. He said to the Kenites, “Go away. Leave the Amalekites so that I won’t destroy you with them, because you showed kindness to the Israelites when they came out of Egypt.” So the Kenites moved away from the Amalekites.
