Deuteronomy 3:13, 14

The rest of Gilead and also all of Bashan, the kingdom of Og, I gave to the half-tribe of Manasseh. (The whole region of Argob in Bashan used to be known as a land of the Rephaites.

Jair, a descendant of Manasseh, took the whole region of Argob as far as the border of the Geshurites and the Maakathites; it was named after him, so that to this day Bashan is called Havvoth Jair.)
