John Gill Commentary Ezekiel 48:5

"And by the border of Manasseh, from the east side unto the west side, Ephraim, one [portion]." — Ezekiel 48:5 (ASV)

And by the border of Manasseh, from the east side unto the west
side, a portion for Ephraim .
Close to the tribe of Manasseh, and the inheritance of it, which is no more reckoned a half, but a whole tribe, and has an inheritance equal to the rest, lay the tribe of Ephraim, and the inheritance assigned to that; even to such believers as are fruitful in grace and good works. Joseph is not mentioned, as in (Ezekiel 47:13) , the two portions there given him being here allotted to his two sons, Manasseh and Ephraim.
