Joshua 17:9-10

9Next the border went down to the Wadi Kanah, south of the wadi, by towns belonging to Ephraim among Manasseh’s towns. But the border of Manasseh was on the north side of the wadi, and ended at the sea.

10The south side belonged to Ephraim and the north side belonged to Manasseh, and the sea was its border. They reached to Asher on the north and to Issachar on the east.
