John Gill Commentary Joshua 17:10

"southward it was Ephraim`s, and northward it was Manasseh`s, and the sea was his border; and they reached to Asher on the north, and to Issachar on the east." — Joshua 17:10 (ASV)

Southward [it was] Ephraim's, and northward [it was] Manasseh's As Ephraim lay to the south of Manasseh, Manasseh lay to the north of Ephraim:

and the sea is his border ; the Mediterranean sea was their boundary on the west:

and they met together in Asher on the north ; that is, on the northwest towards the Mediterranean sea, as, at Mount Carmel:

and in Issachar on the east ; towards Jordan.
