Numbers 21:1-3

When the Canaanite, the king of Arad, who lived in the Negev, heard that Israel was coming by the way of Atharim, he fought against Israel and took some of them captive. So Israel made a vow to the Lord and said, “If You will indeed hand over this people to me, then I will utterly destroy their cities.” The Lord heard the voice of Israel and turned over the Canaanites; then they utterly destroyed them and their cities. And the place was named Hormah.
