Numbers 21:1-3

1When the Canaanite king of Arad, who lived in the Negev, heard that Israel was coming along the road to Atharim, he attacked the Israelites and captured some of them.

2Then Israel made this vow to the Lord: “If you will deliver these people into our hands, we will totally destroy their cities.”

3The Lord listened to Israel’s plea and gave the Canaanites over to them. They completely destroyed them and their towns; so the place was named Hormah.
