Numbers 21:1-2

Authorized (King James) Version

21 And when king Arad the Canaanite, which dwelt in the south, heard tell that Israel came by the way of the spies; then he fought against Israel, and took some of them prisoners. ² And Israel vowed a vow unto the Lord, and said, If thou wilt indeed deliver this people into my hand, then I will utterly destroy their cities.
