“Adjoining the territory

Of Ephraim,

From the east side

To the west side,

Reuben was

One portion.”

Once again, in a very summary fashion of east to west, the territory of Reuben was next to Ephraim. However, in Joshua, chapter 13, Reuben was an east bank territory and had no land on the west side of the Jordan River. Somehow it would be south of Ephraim, maybe in the old Dan territory or the Benjamin territory. From this description, it is hard to tell.
