Joshua 17:9-10

9And the border descended to the Brook Kanah, southward to the brook. These cities of Ephraim are among the cities of Manasseh. The border of Manasseh was on the north side of the brook; and it ended at the sea.

10Southward it was Ephraim’s, northward it was Manasseh’s, and the sea was its border. Manasseh’s territory was adjoining Asher on the north and Issachar on the east.
