Deuteronomy 3:12-17

12“When we took possession of this land at that time, I gave to the Reubenites and the Gadites the territory beginning at Aroer, which is on the edge of the Valley of the Arnon, and half the hill country of Gilead with its cities. 13The rest of Gilead, and all Bashan, the kingdom of Og, that is, all the region of Argob, I gave to the half-tribe of Manasseh. (All that portion of Bashan is called the land of Rephaim. 14Jair the Manassite took all the region of Argob, that is, Bashan, as far as the border of the Geshurites and the Maacathites, and called the villages after his own name, Havvoth-jair, as it is to this day.) 15To Machir I gave Gilead, 16and to the Reubenites and the Gadites I gave the territory from Gilead as far as the Valley of the Arnon, with the middle of the valley as a border, as far over as the river Jabbok, the border of the Ammonites; 17the Arabah also, with the Jordan as the border, from Chinnereth as far as the Sea of the Arabah, the Salt Sea, under the slopes of Pisgah on the east.
