Matthew 13:52
A “scribe” (Matthew 13:52) is the one who, through persistent reading of the scriptures of both the old and the new, has stored up a treasure of knowledge for himself. That is why he blesses those who have brought together in themselves both legal and gospel training, so as to bring out from the treasure things new and old. He also likens these to a scribe, just as elsewhere he says, “I send you wise men and scribes.” See how he does not cast out the old — through which the soul is adorned.

Γραμματεύς ἐστιν ὁ διὰ τῆς ἐπιμόνου ἀναγνώσεως τῶν γραφῶν τῆς τε παλαιᾶς καὶ τῆς νέας θησαυρὸν γνώσεως ἑαυτῷ ἀποθέμενος. διὸ μακαρίζει τοὺς συνενεγκόντας ἐν ἑαυτοῖς νομικὴν παιδείαν καὶ εὐαγγελικήν, ὥστε ἐκβάλλειν ἐκ τοῦ θησαυροῦ νέα καὶ παλαιά. τούτους καὶ γραμματεῖ ὁμοιοῖ καθὼς καὶ ἀλλαχοῦ φησιν· "ἀποστέλλω" ὑμῖν "σοφοὺς καὶ γραμματεῖς". εἶδες πῶς οὐκ ἐκβάλλει τὴν παλαιάν–δι' ὧν καλλωπίζεται ἡ ψυχή.
