Moulton & Milligan — Vocabulary of the Greek NT
ἄγνοια. The connotation of wilful blindness, as in Eph 4.5, is found in P Tebt I. 24% (B.c. 117), where an official reports the misconduct of certain persons whose plans he had frustrated, so that λήγοντες τῆς ἀγνοίας they left the district. The writer had avotas first, and then added y above the line. In the ordinary sense of inadvertence it is common: e.g. BGU IV. 11149 (B.c. 8-7) γέγονεν δὲ kar’ ἄγνοιαν εἰς ὃ κατάπλους ᾿ τὸ αὐτοῦ Κοίντου Καικιλίου Κάστορος ὄνομα. With a A.D.) ἔπτεὶ κατ᾽ ἄγνοιαν τῶν φροντίδων αὐτῶν ἠργάσατο, 12. I. 78% © (iii/a.p.) ἵν’ οὖν μὴ δόξω συνθέσθαι τῇ τοῦ πραγματικοῦ ἀγνοίᾳ ἐπιδίδωμι τὰ βιβλίδια κτὰ. The simple dat. appears with same sense in P Flor II. 1325 (iii/a.p.) ἔλε[ξ]αν πεποιηκέναι ταῦτα ἀγνοίᾳ. For κατὰ ἄγνοιαν, as in Ac 31’, see P Oxy 11. 237% *8 (a.p. 186) ἵνα οἱ συναλλάσσοντες μὴ kat’ ἄγνοιαν ἐνεδρεύονται, “in order that persons entering into agreements may not be defrauded through ignorance” (Edd.).
