Matthew Poole and continuators on Joshua 17:9

9 And the coast descended unto the river Kanah southward of the river: these cities of Ephraim are among the cities of Manasseh , the coast of Manasseh also was on the north-side of the river, and the out-goings of it were at the sea.

Tappuah, and the cities upon the Coast descending to the River, &c. last mentioned.

i. e. Are intermixed with their Cities, which was not strange nor unfit, these two being linked together by a nearer Alliance than the rest.
