Numbers 21:21-26

21Then Israel sent messengers to King Sihon of the Amorites, saying,

22“Let us pass through your land; we will not turn aside into the fields or into the vineyards, nor will we drink water from any well, but we will go along the King’s Highway until we pass your borders.”

23But Sihon did not permit Israel to pass through his border; he gathered all his forces together and went out against Israel into the wilderness. When he came to Jahaz, he fought against Israel.

24But the Israelites defeated him in battle and took possession of his land from the Arnon to the Jabbok, as far as the Ammonites, for the border of the Ammonites was strongly defended.

25So 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 King Sihon of the Amorites. Now he had fought against the former king of Moab and had taken all of his land from his control, as far as the Arnon.
