Numbers 21:24-26

New Revised Standard Version, Anglicised Catholic Edition

²⁴ Israel put him to the sword, and took possession of his land from the Arnon to the Jabbok, as far as to the Ammonites; for the boundary of the Ammonites was strong. ²⁵ Israel took all these towns, and Israel settled in all the towns of the Amorites, in Heshbon, and in all its villages. ²⁶ For Heshbon was the city of King Sihon of the Amorites, who had fought against the former king of Moab and captured all his land as far as the Arnon.
