Exodus 29:33

וְאָכְל֤וּ אֹתָם֙ אֲשֶׁ֣ר כֻּפַּ֣ר בָּהֶ֔ם לְמַלֵּ֥א אֶת־יָדָ֖ם לְקַדֵּ֣שׁ אֹתָ֑ם וְזָ֥ר לֹא־יֹאכַ֖ל כִּי־קֹ֥דֶשׁ הֵֽם׃

ἔδονται αὐτὰ ἐν οἷς ἡγιάσθησαν ἐν αὐτοῖς, τελειῶσαι τὰς χεῖρας αὐτῶν, ἁγιάσαι αὐτούς· καὶ ἀλλογενὴς οὐκ ἔδεται ἀπ’ αὐτοῦ, ἔστιν γὰρ ἅγια.

Y comerán aquellas cosas con las cuales se hizo expiación, para henchir sus manos para ser santificados: mas el extranjero no comerá, porque es cosa santa.

They must eat those things by which atonement was made for their ordination and consecration. But no outsider may eat them, because these things are sacred.
