Deuteronomy 3:13-14

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

14Jair son of Manasseh took all the region of Argob, as far as the border of the Geshurites and the Maachathites. He called them—the Bashan—after his own name, Havvoth-jair’s Villages, as it is the case to this day.)
