Joshua 13:24

"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 Ramoth-Mizpeh, and Betonim; and from Mahanaim unto the border of Debir; and in the valley of 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 Chinneroth, beyond the Jordan eastward. This is the inheritance of the children of Gad according to their families, the cities and the villages thereof."

Gad's territory included the balance of the old empire of Sihon as far north as the Jabbok River and somewhat beyond it. The western boundary was the Jordan River. At the Jordan, Gad controlled the area as far as the southern tip of Lake Galilee (Chinneroth, here). Gad received that part of Ammon's territory that Sihon had conquered. Otherwise, Israel was forbidden to encroach on Ammon's land, but the part they had already lost to Sihon, Israel could acquire. On the southeast, the town of Aroer marked the boundary between Gad and Ammon.

Ramoth-Mizpeh is thought to be the same as Ramoth-Gilead. Gad's territory was famous for "balm," for the "wood of Ephraim" where Absalom's rebellious army was beaten; also Sharon, famous for its roses, was in this territory. Also, as Matthew Henry said, "Here lived those Gadarenes who loved their swine more than their Saviour!"[29]
