Moulton & Milligan — Vocabulary of the Greek NT
ὀγδοήκοντα [page 437]
For the form ὀγδοιήκοντα see P Petr I. 19 .22 ὡς ἐτῶν ὀγδοιήκοντα , and similarly ib. 20 (l) .9 , both of B.C. 225 : cf. Crφnert Mem. Herc , p. 121, Nachmanson p. 46. Mayser ( Gr. p. 15 f.) draws attention to the solitary appearance of ὀδώκοντα on a Theban ostracon of i/B.C., Ostr 323 .6 , and thinks that it may be Ionic. MGr (ὀγδοήντα ), ὀγδόντα .
