Numbers 21:21-26

21And Israel sent messengers to Sihon king of the Amorites, saying, 22Let me pass through thy land: we will not turn into the fields, or into the vineyards; we will not drink of the waters of the well: but we will go along by the king’s highway, until we have past thy borders. 23And Sihon would not permit 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. 24And Israel smote him with the edge of the sword, and possessed his land from Arnon to Jabbok, even to the children of Ammon: for the border of the children of Ammon was strong. 25And Israel took all these cities: and Israel dwelt in all the cities of the Amorites, in Heshbon, and in all its villages.1 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, even to Arnon.
