Joshua 17:9-10

9From there the border continued southward to the Brook of Kanah. There were cities belonging to Ephraim among the cities of Manasseh, but the border of Manasseh was on the north side of the brook and ended at the Sea.1

10Ephraim’s territory was to the south, and Manasseh’s was to the north, having the Sea as its border and adjoining Asher on the north and Issachar on the east.
