Joshua 13:24-27

And Moses gave unto the tribe of Gad, unto the children of Gad, according to their families. And their border was Jazer, and all the cities of Gilead, and half the land of the children of Ammon, unto Aroer that is before Rabbah; and from Heshbon unto Ramath-mizpeh, and Betonim; and from Mahanaim unto the border of Debir; and in the valley, Beth-haram, and Beth-nimrah, and Succoth, and Zaphon, the rest of the kingdom of Sihon king of Heshbon, the Jordan and the border thereof, unto the uttermost part of the sea of Chinnereth beyond the Jordan eastward.
