Moulton & Milligan — Vocabulary of the Greek NT
μέγεθος [page 393]
μέγεθος , which in the NT is confined to Eph_1:19 in the general sense of greatness, is common in our sources as a ceremonial title, e g. P Oxy I. 71 i. 4 (petition to the Prefect A.D. 303) τὴν ἱκ [ετ ]ηρίαν προσάγω εὔελπις ὢν τῆς ἀπὸ τοῦ σοῦ μεγέθους δικαιοκρισίας τυχεῖν , I make my petition to you with full confidence that I shall obtain justice from your highness (Edd.), and ib . XII. 1467 .18 (A.D. 263) where a woman, being blessed with children and able to write with the greatest ease, claims from the Prefect the right to act without a guardian διὰ τούτων μου τῶ [ν ] βιβλειδίων προσ̣φω ( l. προσφωνῶ ) τῷ σῷ μεγέθι πρὸς τὸ δύνασθαι ἀνεμποδίστως ἃς ἐντεῦθεν ποιοῦμαι οἰκ [ον ]ομία [ς ] διαπράσσεσθαι , I appeal to your highness by this my application with the object of being enabled to carry out without hindrance all the business which I henceforth transact (Edd.). The transition to this usage is seen in such a passage as P Tebt II. 326 .4 ( c. A.D. 266) ἐπὶ τὸ σὸν μέγεθος καταφεύγω , I take refuge in your power a widow s petition to the Prefect asking that her brother might be appointed guardian of her daughter : cf. P Strass I. 5 .6 (A.D. 262) κατέφυγον ἐπὶ τὸ μέγεθος τοῦ λαμπροτάτου Θεοδότου ἡγεμόνος . We may cite from the inscrr. OGIS 519 .24 ( c. A.D. 245) περὶ ὧν ἁπά [ντων ἐγράφη πρὸς τὸ σόν ,] Σεβαστέ , μέγεθος , and C. and B. ii. p. 700, No. 635 .4 ἐνορκιζόμεθα δὲ τὸ μέγεθος τοῦ θεοῦ καὶ τοὺς καταχθονίους δαίμονας μηδένα ἀδικῆσαι τὸ μνημῖον , where Ramsay notes that the expression τ . μέγεθος τ . θεοῦ is not native Phrygian, and is probably due to Christian feeling or Jewish thought.
