Deuteronomy 3:12-17

Distribution of the Transjordanian Allotments

3:12 This 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. 3:13 The 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. 3:14 Jair, 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.) 3:15 I gave Gilead to Machir. 3:16 To 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. 3:17 The 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.
