Now these are the names of the tribes - See the division mentioned Num 34:7-12, which casts much light upon this.

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 Eze 47:13, the two portions there given him being here allotted to his two sons, Manasseh and Ephraim.

eze 48:6And by the border of Ephraim, from the east side unto the west side, a portion for Reuben. Who, through his sin, lost his birthright; but now, his sin being forgiven and forgotten, has a portion assigned him upon the border of Ephraim, and next to the tribe of Judah; when in Moses and Joshua's time it lay on the other side Jordan: this points to such persons that shall have their lot and portion in spiritual things; that "see the Son", that look to Christ alone for righteousness, peace, pardon, and eternal life.

Manasseh--The intercourse and unity between the two and a half tribes east of the Jordan, and the nine and a half west of it, had been much kept up by the splitting of Manasseh, causing the visits of kinsmen one to the other from both sides of the Jordan. There shall be no need for this in the new order of things.
