Moses had given the land of Bashan to East Manasseh. Joshua gave land on the west side of the Jordan River to West Manasseh. And he sent them to their homes and he blessed them.
So Moses gave that land to the tribes of Gad, Reuben, and East Manasseh. (Manasseh was Joseph’s son.) That land had been the kingdom of Sihon, king of the Amorites, and the kingdom of Og, king of Bashan, as well as all the cities and the land around them.
