Numbers 21:24-26

BSB(i) 24 And Israel put him to the sword and took possession of his land, from the Arnon to the Jabbok—but only up to the border of the Ammonites, because it was fortified. 25 Israel captured all the cities of the Amorites and occupied them, including Heshbon and all its villages. 26 Heshbon was the city of Sihon king of the Amorites, who had fought against the former king of Moab and taken all his land as far as the Arnon.
