Num 21:1-3

The Bronze Serpent 1When the Canaanite, the king of Arad, who lived in the Negeb, heard that Israel was coming by the way of Atharim, he fought against Israel and took some of them captive.2Then Israel made a vow to the Lord and said, “If you will indeed give this people into our hands, then we will utterly destroy their towns.”3The Lord listened to the voice of Israel, and handed over the Canaanites; and they utterly destroyed them and their towns; so the place was called Hormah.
