Keil, Commentary on Matthew, the passage cited).

Moulton & Milligan — Vocabulary of the Greek NT
ἑπτά [page 252]
As we have no fresh light from our sources, it lies outside our sphere to discuss the uses of this number in the NT, but reference may be made to the notes by Allen on Mar_16:9 , and by Moffatt (in EGT ) on Rev_5:1 . Note also Act_12:10 D κατέβησαν τοὺς ζ̄ βαθμούς and Ev. Petr. 8 ἐπέχρισαν ἑπτὰ σφραγῖδας . MGr ἑφτά shows the aspirate in compensation for the loss (in pronunciation) of the rough breathing.
