Numbers 21:23–26

But Sihon would not let Israel pass through his territory. He mustered his entire army and marched out into the wilderness against Israel. When he reached Jahaz, he fought with Israel. Israel, however, put him to the sword and took over his land from the Arnon to the Jabbok, but only as far as the Ammonites, because their border was fortified. Israel captured all the cities of the Amorites and occupied them, including Heshbon and all its surrounding settlements. Heshbon was the city of Sihon king of the Amorites, who had fought against the former king of Moab and had taken from him all his land as far as the Arnon.

But Sihon would not let Israel travel through his territory. Instead, he gathered his whole army and went out to confront Israel in the wilderness. When he came to Jahaz, he fought against Israel. Israel struck him with the sword and took possession of his land from the Arnon to the Jabbok, but only up to the Ammonite border, because it was fortified.

Israel took all the cities and lived in all these Amorite cities, including Heshbon and all its surrounding villages. Heshbon was the city of King Sihon of the Amorites, who had fought against the former king of Moab and had taken control of all his land as far as the Arnon.

But King Sihon refused to let them cross his territory. Instead, he mobilized his entire army and attacked Israel in the wilderness, engaging them in battle at Jahaz. But the Israelites slaughtered them with their swords and occupied their land from the Arnon River to the Jabbok River. They went only as far as the Ammonite border because the boundary of the Ammonites was fortified.

So Israel captured all the towns of the Amorites and settled in them, including the city of Heshbon and its surrounding villages. Heshbon had been the capital of King Sihon of the Amorites. He had defeated a former Moabite king and seized all his land as far as the Arnon River.

But Sihon did not allow Israel to go through his territory. Sihon gathered all his people and went out to meet Israel; he came to the desert, to Jahaz, and he fought against Israel. But Israel struck him with the edge of the sword, and they took possession of his land from Arnon to Jabbok, until the Ammonites, because the boundary of the Ammonites was strong. Israel took all these cities, and Israel inhabited all the cities of the Amorites, in Heshbon, and in all its environs. Because Heshbon was the city of Sihon king of the Amorites, who had fought against the former king of Moab and taken all his land from his hand until Arnon.

And Sihon would not suffer Israel to pass through his border: but Sihon gathered all his people together, and went out against Israel into the wilderness: and he came to Jahaz, and fought against Israel. And Israel smote him with the edge of the sword, and possessed his land from Arnon unto Jabbok, even unto the children of Ammon: for the border of the children of Ammon was strong. And Israel took all these cities: and Israel dwelt in all the cities of the Amorites, in Heshbon, and in all the villages thereof. For 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, even unto Arnon.
