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 Israel and captured some of them.

2Then Israel vowed to Adonai and stated, “If you deliver this people into our hand, we will put their cities under the ban of destruction!”

3Adonai listened to Israel’s plea and delivered up the Canaanites. They put them and their cities under the ban of destruction. So the name of the place was called Hormah.
