Verses 9-10a further define the relation between the two neighboring tribes; verse 10b locates West Manasseh in relation to the tribe of Asher and the tribe of Issachar.

It may be more effective to translate verses 9-10 as a unit:

• From there the southern border followed the stream Kanah westward to the Mediterranean Sea. The main territory of Manasseh was located north of the Kanah stream, but south of it were some cities that belonged to the tribe of Ephraim, even though they were in the territory of Manasseh. In the northwest Manasseh bordered on the tribe of Asher, and in the northeast it bordered on the tribe of Issachar.
