Joshua 17:11-12

11And Manasseh had in Issachar and in Asher, Beth-shean and its dependent villages, and Ibleam and its dependent villages, and the inhabitants of Dor and its dependent villages, and the inhabitants of En-Dor and its dependent villages, and the inhabitants of Taanach and its dependent villages, and the inhabitants of Megiddo and its dependent villages, the three hilly regions.

12But the children of Manasseh could not dispossess [the inhabitants of] those cities; and the Canaanites would dwell in that land.
