וְהָיְתָ֤ה לָהֶם֙ לְֽנַחֲלָ֔ה אֲנִ֖י נַֽחֲלָתָ֑ם וַאֲחֻזָּ֗ה לֹֽא־תִתְּנ֤וּ לָהֶם֙ בְּיִשְׂרָאֵ֔ל אֲנִ֖י אֲחֻזָּתָֽם׃
Quant à ce qui doit être leur héritage, c’est moi qui serai leur héritage; de possession, vous ne leur en donnerez point en Israël: moi, je serai leur possession.
Tze'enah Ure'enah
“This shall be their portion” [44:28]. The priesthood should be a guarantor and an inheritance for them. They should take no fields and cities, like the rest of Israel. I, God, am their inheritance and guarantor for them. They will have sacrifices to eat, meal offerings, sin offerings, and guilt offerings. Everything that is sanctified as holy will be theirs. The first fruits, the terumah, and the hallah offering should be given to the priest to eat. The Holy One will give the Israelite a blessing in his house because of this merit.
Rashi
It shall be to them the priesthood, for an inheritance.
