Unto the river Kanah - Literally, the river or valley of the reeds, translated by the Vulgate, vallis arundintei. The tribe of Manasseh appears to have been bounded on the north by this torrent or valley, and on the south by the Mediterranean Sea.
These cities - The text is possibly corrupt. The intention seems to be to state that the cities lying south of the river, though within the limits of Manasseh, were in fact made over to Ephraim, and were among the “separate cities” Joshua 16:9. On the contrary, the north bank of the river, both land and towns, belonged to Manasseh exclusively.
