Deuteronomy 2:32-36

32“Then Sihon came out against us—he and all his people—to battle at Jahaz.

33Adonai our God gave him over to us, and we struck him down along with his sons and all his people.

34We captured all his cities at that time, and utterly put under a ban of judgment every city—men, women and children. We left no survivor.

35We took only the livestock as plunder for ourselves, as the spoils of the cities we captured.

36From Aroer which is on the edge of the Wadi Arnon and the city by the wadi, all the way up to the Gilead, there was not a town too high for us. Adonai our God gave everything over to us.
