Joshua 13:24-26

24And Moses gave [a portion] to the tribe of Gad, to the children of Gad according to their families.

25And their territory was Jaazer, and all the cities of Gilead, and half the land of the children of Ammon, to Aroer which is before Rabbah;

26and from Heshbon to Ramath-Mizpeh, and Betonim; and from Mahanaim to the border of Debir;
