1 Samuel 15:4-6

Saul called the army together at Telaim and prepared them to go to war—two hundred companies of infantry from Israel and another ten companies from Judah. Saul marched to Amalek City and hid in the canyon. Then Saul got word to the Kenites: “Get out of here while you can. Evacuate the city right now or you’ll get lumped in with the Amalekites. I’m warning you because you showed real kindness to the Israelites when they came up out of Egypt.” And they did. The Kenites evacuated the place.
