According to the author of the book of Joshua, this verse means that the people from the tribe of Manasseh had land in different places where other people lived, like towns and cities, even in three big areas. It shows how the land was divided and shared among the people.
Joshua 17:11: And Manasseh had in Issachar and in Asher Bethshean and her towns, and Ibleam and her towns, and the inhabitants of Dor and her towns, and the inhabitants of Endor and her towns, and the inhabitants of Taanach and her towns, and the inhabitants of Megiddo and her towns, [even] three countries.
In Joshua 17:11, there might be a contradiction or inconsistency in how the territories and cities are described, as other parts of the Bible might assign these places to different tribes or offer different details about the regions. Such discrepancies can arise from variations in ancient texts or differing oral traditions over time.
