1 Samuel 15:4-6

4 So Saul called his army to come together. The men met at Telaim and Saul counted them. There were 200,000 soldiers from Israel and another 10,000 men from Judah's tribe. 5 Saul and his army went to the city of the Amalekites. They waited in a small valley to attack their enemy. 6 Saul said to the Kenite people, ‘Go away from here! I will kill the Amalekites, but I do not want to kill you. You were kind to the Israelites when they came out from Egypt.’ So the Kenites moved away from the Amalekites.
