Numenius of Apamea, Fragmenta

8 Καὶ ἐν τῇ τρίτῃ δὲ βίβλῳ Μωσέως ὁ αὐτὸς τάδε λέγων μνημονεύει. Τὰ δ’ ἐξῆς Ἰαννῆς καὶ Ἰαμβρῆς Αἰγύπτιοι ἱερογραμματεῖς, ἄνδρες οὐδενὸς ἥττους μαγευταὶᵃ κριθέντες εἶναι, ἐπὶ Ἰουδαίων ἐξελαυνομένων ἐξ Αἰγύπτου. Μουσαίῳᵇ γοῦν τῷ Ἰουδαίων ἐξηγησαμένῳ, ἀνδρὶ γενομένῳ θεῷ εὔξασθαι δυνατωτάτῳ, οἱ παραστῆναι ἀξιωθέντες ὑπὸ τοῦ πλήθους τοῦ τῶν Αἰγυπτίων, οὗτοι ἦσαν, τῶν τε συμφορῶν ἃς ὁ Μουσαῖος ἐπῆγε τῇ Αἰγύπτῳ, τὰς νεανικωτάτας αὐτῶν ἐπιλύεσθαι ὤφθησαν δυνατοί. Διὰ δὴ τούτων ὁ Νουμήνιος καὶ τοῖς ὑπὸ Μωσέως ἐπιτελεσθεῖσι παραδόξοις θαύμασι, καὶ αὐτῷ δὲ ὡς θεοφιλεῖ γενομένῳ μαρτυρεῖ.

8. And in the third book the same [author] mentions Moses, saying the following: "Next came Jannes and Jambres, Egyptian sacred scribes, men judged to be second to none in magic, at the time when the Jews were being driven out of Egypt. It was they, at any rate, whom the people of Egypt thought fit to stand against Musaeus, who led the Jews, a man who had proved most powerful in praying to God; and of the calamities which Musaeus brought on Egypt they were seen to be able to undo the most violent." Through these [words] Numenius bears witness both to the extraordinary wonders performed by Moses and to Moses himself as one dear to God.
