Numbers 21:1-3

1When the Canaanite king of Arad, who lived in the Negev, heard that the Israelites were coming on the road to Atharim, he fought them and took some of them as prisoners.

2Then the Israelites made this vow to the Lord: “If you will hand these people over to us, we’ll destroy their cities because you’ve claimed them.”

3The Lord listened to the Israelites and handed the Canaanites over to them. They destroyed the Canaanites and their cities. So they called the place Hormah [Claimed for Destruction].
