Moulton & Milligan — Vocabulary of the Greek NT
ὀγδοήκοντα. For the form ὀγδοιήκοντα see P Petr I. 197? ὡς ἐτῶν ὀγδοιήκοντα, and similarly 2. 20(1)®, both of B.c. 225: cf. Croénert 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., Ost 3238, and thinks that it may be Ionic. MGr (ὀγδοήντα), ὀγδόντα.
