Deuteronomy 3:15

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

14 Jair the son of Manasseh took all the region of Argob, to the border of the Geshurites and the Maacathites, and called them, even Bashan, after his own name, Havvoth Jair, to this day.)

15 I gave Gilead to Machir.

16 To the Reubenites and to the Gadites I gave from Gilead even to the valley of the Arnon, the middle of the valley, and its border, even to the river Jabbok, which is the border of the children of Ammon;

17 the Arabah also, and the Jordan and its border, from Chinnereth even to the sea of the Arabah, the Salt Sea, under the slopes of Pisgah eastward.
