Deuteronomy 3:12-13

Of the land that we possessed at that time, I gave the Reubenites and the Gadites the territory north of Aroer along the Brook Arnon and half the hill country of Gilead with its towns. I gave the half-tribe of Manasseh the rest of Gilead and all of Bashan, Og’s kingdom—all the region of Argob, which takes in all of Bashan. This used to be known as the Land of the Rephaites.
