Deuteronomy 2:30-37

30But Sihon king of Heshbon would not let us pass by him, because Adonai your God stiffened his spirit and hardened his heart, in order to hand him over to you this very day.

31“Adonai said to me, ‘See, I have begun to give Sihon and his land over to you—begin to take possession in order to take hold of his land.’

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.

37Only you did not come near the land of the sons of Ammon—all along the Wadi Jabbok and the cities of the hill country and wherever Adonai our God had commanded.
