Joshua 17:9-10

9Then the border went down to the brook of Kanah, south of the brook (these cities belonged to Ephraim, among the cities of Manasseh), and Manasseh’s border was on the north side of the brook and it ended at the sea.

10The land on the south side belonged to Ephraim and that on the north side was Manasseh’s, and the sea was their border; they reached to [the territory of] Asher on the north and to [the territory of] Issachar on the east.
