Deuteronomy 3:11-15

(For only Og king of Bashan was left of the remnant of the Rephaim. Behold, his bed was a bed of iron; it is in Rabbah of the sons of Ammon. Its length was nine cubits, and its width four cubits by the usual cubit.)

“So we took possession of this land at that time. From Aroer, which is by the Valley of Arnon, and half the hill country of Gilead and its cities I gave to the Reubenites and to the Gadites.

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

Jair the son of Manasseh took all the region of Argob as far as the border of the Geshurites and the Maacathites, that is, Bashan, and named it after his own name: Havvoth-jair, as it is to this day.)

To Machir I gave Gilead.
