Within Issachar’s and Asher’s territory Manasseh was assigned Beth Shean, Ibleam, the residents of Dor, En Dor, the residents of Taanach, the residents of Megiddo, the three of Napheth, and the towns surrounding all these cities.
The men of Manasseh did not conquer Beth Shan, Taanach, or their surrounding towns. Nor did they conquer the people living in Dor, Ibleam, Megiddo or their surrounding towns. The Canaanites managed to remain in those areas.
