Joshua 13:8-11

The tribes of Reuben, Gad, and the half-tribe of Manasseh had already received their portion of the land on the east side of the Jordan, which YAHWEH’s servant Moses had assigned to them. These tribes occupied the land as far southeast as the city of Aroer on the edge of the Arnon Valley, including the city in the middle of the valley and the plain from Dibon in the south, north to Medeba. Their territory went as far east as the border of Ammon, including all the cities over which King Sihon, the Amorite king, ruled over from Heshbon. It also included Gilead, the land of the Geshurites and Maacathites, all of Mount Hermon, and all of Bashan to its eastern boundary of Salecah.
