Joshua 13:8-11

Half the tribe of Manasseh and the tribes of Reuben and Gad had already received their grants of land on the east side of the Jordan, for Moses, the servant of the LORD, had previously assigned this land to them. Their territory extended from Aroer on the edge of the Arnon Gorge (including the town in the middle of the gorge) to the plain beyond Medeba, as far as Dibon. It also included all the towns of King Sihon of the Amorites, who had reigned in Heshbon, and extended as far as the borders of Ammon. It included Gilead, the territory of the kingdoms of Geshur and Maacah, all of Mount Hermon, all of Bashan as far as Salecah
