Deuteronomy 3:10

So Moses gave to them, to the sons of Gad and to the sons of Reuben and to the half-tribe of Joseph’s son Manasseh, the kingdom of Sihon, king of the Amorites and the kingdom of Og, the king of Bashan, the land with its cities with their territories, the cities of the surrounding land.

“Then you came to this place, and Sihon the king of Heshbon and Og the king of Bashan came out to meet us for battle, but we struck them down;

Now these are the kings of the land whom the sons of Israel struck down, and whose land they possessed beyond the Jordan to the east toward the sunrise, from the valley of the Arnon as far as Mount Hermon, and all the Arabah to the east:

and ruled over Mount Hermon and Salecah and all Bashan, as far as the border of the Geshurites and the Maacathites, and half of Gilead, as far as the border of Sihon king of Heshbon.

Geber the son of Uri, in the land of Gilead, the country of Sihon king of the Amorites and of Og king of Bashan; and he was the only deputy who was in the land.

Now the sons of Gad lived opposite them in the land of Bashan as far as Salecah.
