10 In general, however, the land south of the ravine belonged to Ephraim, and the land north of the ravine belonged to Manasseh. Manasseh's boundary ran along the northern side of the ravine and ended at the Mediterranean Sea. North of Manasseh was the territory of Asher, and to the east was the territory of Issachar.
Matthew Henry's Commentary on Joshua 17:10
Commentary on Joshua 17:7-13
(Read Joshua 17:7-13)
There was great communication between Manasseh and Ephraim. Though each tribe had its inheritance, yet they should intermix one with another, to do good offices one to another, as became those, who, though of different tribes, were all one Israel, and were bound to love as brethren. But they suffered the Canaanites to live among them, against the command of God, to serve their own ends.
