Numbers 21:23-26

23 aBut Sihon would not allow Israel to pass through his territory. He gathered all his people together and went out against Israel to the wilderness and bcame to Jahaz and fought against Israel. 24 cAnd Israel defeated him with the edge of the sword and took possession of his land from the Arnon to the dJabbok, as far as to the Ammonites, for the border of the Ammonites was strong. 25And Israel took all these cities, and Israel settled in all the cities of the Amorites, in Heshbon, and in all its villages. 26For Heshbon was the city of Sihon the king of the Amorites, who had fought against the former king of Moab and taken all his land out of his hand, as far as the Arnon.
