Joshua 13:25-29

Their territory was Jazer and all the cities of Gilead, and half the land of the sons of Ammon, as far as Aroer which is opposite Rabbah;

and from Heshbon as far as Ramath-mizpeh and Betonim, and from Mahanaim as far as the border of Debir;

and in the valley, Beth-haram, Beth-nimrah, Succoth, and Zaphon, the rest of the kingdom of Sihon king of Heshbon, with the Jordan as a border, as far as the lower end of the Sea of Chinnereth beyond the Jordan to the east.

This is the inheritance of the sons of Gad according to their families, the cities and their villages.

Moses also gave an inheritance to the half-tribe of Manasseh; and it was for the half-tribe of the sons of Manasseh according to their families.
