The Canaanite king of Arad lived in the Negev. He heard that the Israelites were coming on the road to Atharim, so the king went out and attacked the Israelites. Arad captured some of the people and made them prisoners.
The Lord listened to the Israelites and helped them defeat the Canaanites. They completely destroyed the Canaanites and their cities. So that place was named Hormah.
The Amalekites and the Canaanites living in the hill country came down and attacked the Israelites and easily defeated them and chased them all the way to Hormah.
