The roster of families and households for the descendants of Asher listed the men by name who were at least 20 years old and eligible for military duty.
This is the territory for the families descended from Ephraim. The eastern border of the land they inherited is from Ataroth Addar to Upper Beth Horon.
At Tappuah the border goes west along the Kanah River and ends at the Mediterranean Sea. This is the land given as an inheritance to the families of the tribe of Ephraim
The lot was drawn for the tribe of Manasseh, because Manasseh was Joseph’s firstborn. Machir, Manasseh’s firstborn, the ancestor of the people living in Gilead, had received Gilead and Bashan because he was a soldier.
So the tribes of Reuben and Gad and half of the tribe of Manasseh left the rest of the Israelites at Shiloh in Canaan. They returned to Gilead. This was their own possession which they had captured as the Lord had instructed them through Moses.
