Numbers 21:2-3

Brenton(i) 2 And Israel vowed a vow to the Lord, and said, If thou wilt deliver this people into my power, I will devote it and its cities to thee. 3 And the Lord hearkened to the voice of Israel, and delivered the Chananite into his power; and Israel devoted him and his cities, and they called the name of that place Anathema.
