Deuteronomy 3:12-17

12This is the land we brought under our control at that time: The territory extending from Aroer by the Wadi Arnon and half the Gilead hill country with its cities I gave to the Reubenites and Gadites.

13The rest of Gilead and all of Bashan, the kingdom of Og, I gave to half the tribe of Manasseh. (All the region of Argob, that is, all Bashan, is called the land of Rephaim.

14Jair, son of Manasseh, took all the Argob region as far as the border with the Geshurites and Maacathites (namely Bashan) and called it by his name, Havvoth-Jair, which it retains to this very day.)

15I gave Gilead to Machir.

16To the Reubenites and Gadites I allocated the territory extending from Gilead as far as Wadi Arnon (the exact middle of the wadi was a boundary) all the way to the Wadi Jabbok, the Ammonite border.

17The Arabah and the Jordan River were also a border, from the sea of Chinnereth to the sea of the Arabah (that is, the Salt Sea), beneath the watershed of Pisgah to the east.
