Deuteronomy 3:13 "The rest of Gilead and all Bashan, the kingdom of Og, I gave to the half-tribe of Manasseh, all the region of Argob (concerning all Bashan, it is called the land of Rephaim.

Joshua 17:1 Now this was the lot for the tribe of Manasseh, for he was the firstborn of Joseph. To Machir the firstborn of Manasseh, the father of Gilead, were allotted Gilead and Bashan, because he was a man of war. (NASB ©1995)
