Jamieson, Fausset & Brown, on Ezek 47:13

“Thus saith the Lord God: This is the border, by which you shall possess the land according to the twelve tribes of Israel: for Joseph hath a double portion.”

“The redivision of the land: the boundaries. The latter are substantially the same as those given by Moses in Num. 34:1-29; they here begin with the north, but in Numbers they begin with the south (Num 34:3). It is only Canaan proper, exclusive of the possession of the two and a half tribes beyond Jordan, that is here divided. Joseph . . . two portions--according to the original promise of Jacob (Gen 48:5, Gen 48:22). Joseph's sons were given the birthright forfeited by Reuben, the first-born (Ch1 5:1). Therefore the former is here put first. His two sons having distinct portions make up the whole number twelve portions, as he had just before specified "twelve tribes of Israel"; for Levi had no separate inheritance, so that he is not reckoned in the twelve.”
