The border went west from Tappuah to the stream Kanah and ended at the Mediterranean Sea. This was the land given to the families of the tribe of Ephraim as their possession,
A part of the land west of the Jordan was assigned to some of the families descended from Joseph's older son Manasseh. Machir, the father of Gilead, was Manasseh's oldest son and a military hero, so Gilead and Bashan, east of the Jordan, were assigned to him.
So the people of the tribes of Reuben, Gad, and East Manasseh went back home. They left the rest of the people of Israel at Shiloh in the land of Canaan and started out for their own land, the land of Gilead, which they had taken as the Lord had commanded them through Moses.
