21 Then the Israelites sent messengers to Sihon the Amorite king:
22 "Let us pass through your land. We won’t turn aside into a field or vineyard. We won’t drink water from a well. We will walk on the King’s Highway until we cross your border."
23 But Sihon wouldn’t allow the Israelites to cross his border. Sihon gathered all his people and went out to meet the Israelites in the desert. When he came to Jahaz, he attacked the Israelites.
24 The Israelites struck him down with their swords and took possession of his land from the Arnon to the Jabbok, as far as the Ammonites, for the border of the Ammonites was fortified.
25 The Israelites took all these cities. Then the Israelites settled in all the cities of the Amorites, in Heshbon and all its villages.
26 Now Heshbon was the city of Sihon the Amorite king who had fought against the former king of Moab. He had taken all his land from him as far as the Arnon.
27 Therefore, the poets say:"Come to Heshbon, let it be built.Let the city of Sihon be established.
