Numbers 21:1-2

Amplified Bible

Arad Conquered

21 When the Canaanite, the king of Arad, who lived in the Negev (the South country) heard that Israel was coming by the way of Atharim [the route traveled by the spies sent out by Moses], he fought against Israel and took some of them captive. ² So Israel made a vow to the Lord, and said, “If You will indeed hand over these people to me, then I will utterly destroy their cities.”
