ἀποδείκνυμι [page 60] P Alex 4 .6 (iii/B.C.) (= Witkowski .2 , p. 51) ἀποδείξομέν σε , we shall report you. For the middle cf. Syll 521 .19 (B.C. 100) the newly admitted ephebi ποιησάμενοι . . . μελέτην ἐν τοῖς ὅπλοις ἀπεδείξαντο τοῖς . . . Θησείοις . The verb is very common in the sense of appoint or nominate : in P Ryl II. 153 .17 (A.D. 138 61) ἀποδίγνυμι τὸν υἱόν as heir to my estate. Generally it is used of proclaiming an appointment to public office. Thus in the rough draft of a public proclamation of the accession of Nero we are told ὁ δὲ τῆς οἰκουμένης καὶ προσδοκηθεὶς καὶ ἐλπισθεὶς Αὐτοκράτωρ ἀποδέδεικται , the expectation and hope of the world has been declared Emperor (P Oxy VII. 1021 .5 ff. , A.D. 54), and in the same Emperor s speech to the Greeks he describes himself as δ [η ]μαρχικῆς ἐξουσίας τὸ τρισκαιδέκατον ἀποδεδειγμένος = designatus ( Syll 376 .33 , A.D. 67, with Dittenberger s note). Other examples are P Petr III. 36 ( a ) verso .17 ἐπ [ὶ ] τῶν ἀποδεδειγμένων ἐπισκόπων in the presence of the appointed supervisors, P Gen I. 36 .2 (ii/A.D.) Ἀνουβίωνι ἀποδ [εδε ]ιγμένῳ γυμνασιάρχῳ , and from the inscriptions OGIS 437 .92 (i/B.C.) οἱ ὑφ᾽ ἑκατέρων τῶν δήμων ἀποδειχθέντες ἄνδρες ἐπὶ τῶν συλλύσεων Σαρδιανῶν , Syll 409 .11 (ii/A.D.) ἀποδειχ [θέν ]τος ὑπὸ θεοῦ Ἁδριανοῦ , etc. This use of the verb adds point to 2Th_2:4 , where the man of lawlessness is decribed as ἀποδεικνύντα ἑαυτὸν ὅτι ἔστιν θεός he actually proclaims himself as God (see further Milligan ad l. ). For the other meaning, demonstrate, as in Act_25:7 , cf. P Par 15 .34 f. (B.C. 120) ἠρώτησεν τὸν Ἑρμίαν εἴ τινα ἀποδείξιν παράκειται (so Radermacher Gr. p. 152 f.) ὥς ἐστιν αὐτοῦ προγονική , P Lond. 904 .84 (A.D. 104 see above, under ἀπογραφή ) (= III. p. 126) οἱ ἀποδ [εί ]ξαντες ἀναγκ [αίαν α ]ὐ̣τῶν τὴν παρου [σίαν , who have proved their inability to return home for the census, P Fay 32 .15 (A.D. 131) πρότερον ἀποδίξω ὑπάρχειν I will first establish my title to the ownership (Edd.), and BGU II. 388 ii. 19 (ii/iii A.D.) ἐκ τῆς κατ᾽ οἰκίαν ἀπογραφῆς ἀποδείκνυται , τίνος ἐστὶν δοῦλος . The verb in MGr (ἀποδείχνω ) means prove.
