καὶ μὴν καὶ τὸ τῶν ἱερέων αὖ γένος, ὡς τὸ νόμιμόν φησι, παρὰ μὲν ἡμῶν δωρεὰς θεοῖς διὰ θυσιῶν ἐπιστῆμόν (290d) ἐστι κατὰ νοῦν ἐκείνοις δωρεῖσθαι, παρὰ δὲ ἐκείνων ἡμῖν εὐχαῖς κτῆσιν ἀγαθῶν αἰτήσασθαι: ταῦτα δὲ διακόνου τέχνης ἐστί που μόρια ἀμφότερα.
eng tr. Jowett 1817-1893STRANGER:
There is also the priestly class, who, as the law declares, know how to give the gods gifts from men in the form of sacrifices which are acceptable to them, and to ask on our behalf blessings in return from them. Now both these are branches of the servile or ministerial art.
