Deuteronomy 3:12-17

12And this land we took in possession at that time. From Aroer, which is by the river Arnon, and the half of mount Gilead, and its cities, I gave to the Reubenites and to the Gadites;

13and the rest of Gilead, and all Bashan, the kingdom of Og, I gave to half the tribe of Manasseh. (The whole region of Argob, even all Bashan, is called a land of giants.

14Jair the son of Manasseh took the whole region of Argob as far as the border of the Geshurites and Maachathites, and called Bashan after his own name, Havoth-Jair, to this day.)

15And I gave Gilead to Machir.

16And to the Reubenites and to the Gadites I gave from Gilead even to the river Arnon, the middle of the ravine and its border, as far as the river Jabbok, the border of the children of Ammon;

17the plain also, and the Jordan, and [its] border from Chinnereth as far as the sea of the plain, the salt sea, under the slopes of Pisgah eastward.
