Deuteronomy 3:13-14

The rest of Gilead and all of Bashan, the kingdom of Og, I gave to the half-tribe of Manasseh, that is, all the region of Argob (concerning all Bashan, it is called the land of Rephaim. Jair the son (descendant) of Manasseh took all the region of Argob as far as the border of the Geshurites and the Maacathites, that is Bashan, and called it after his own name, Havvoth (the villages of) Jair, as it is called to this day.)
