Joshua 12:2-3

2They killed Sihon, king of the Amorites, who lived in Heshbon. He ruled half of the Gilead region. That is from Aroer that was on the edge of the Arnon valley, as far as the Jabbok river. The Ammonites had the land on the other side of the river.

3King Sihon's land also went along the east side of the Jordan Valley from the sea of Galilee to the Salt Sea. His land went south to Beth Jeshimoth and as far as Pisgah mountain.
