Joshua 16:8

The border went out from Tappuah westward. This would seem to be a more minute description of the border line drawn from the sea to Michmethah above. Tappuah seems to have been near Mich-methah, and on the border ( Joshua 17:8 ) of Manasseh. According to Knobel, Tappuah signifies plain, which is a little inconsistent with his idea that Michmethah, close by, was the watershed. Tappuah elsewhere signifies apple. Unto the river Trench. The winter-bound torrent Kanah, so named from its reeds and canes, formed the border between Ephraim and Manasseh. And the goings out (literally, extremities ) thereof were at the sea This is the only possible interpretation of the passage, in spite of the obscurity caused by the same word being used for "sea" and "west."
