Deuteronomy 3:13-14

CLV(i) 13 The rest of Gilead and all of Bashan, the kingdom of Og, I gave to the half tribe of Manasseh, including the whole district of Argob. All of that Bashan is called the country of the Rephaim. 14 Jair son of Manasseh, he took the whole district of Argob as far as the boundary of the Geshurite and the Maachathite and called them (that is, Bashan) by his own name, Havvoth-jair, until this day.
