Joshua 17:11-13

11Within 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.

12But the men of Manasseh were unable to conquer these cities; the Canaanites managed to remain in those areas.

13Whenever the Israelites were strong militarily, they forced the Canaanites to do hard labor, but they never totally conquered them.
