Joshua 13:8, 10, 24-28

East Manasseh and the tribes of Reuben and Gad had received their land. The LORD’s servant Moses had given them the land east of the Jordan River.

All the towns ruled by Sihon king of the Amorites, who ruled in the city of Heshbon, were in that land. The land continued to the area where the Ammonites lived.

This is the land Moses gave to the tribe of Gad, to all its family groups: the land of Jazer and all the towns of Gilead; half the land of the Ammonites that went as far as Aroer near Rabbah; the area from Heshbon to Ramath Mizpah and Betonim; the area from Mahanaim to the land of Debir; in the valley, Beth Haram, Beth Nimrah, Succoth, and Zaphon, the other land Sihon king of Heshbon had ruled east of the Jordan River and continuing to the end of Lake Galilee. All this land went to the family groups of Gad, including all these towns and their villages.
