Moulton & Milligan — Vocabulary of the Greek NT
ἐπίγνωσις is found in P Tebt I. 2811 (c. B.c. 114) πρὸς τὸ μὴ ἕκαστα én’ ἐπίγνωσιν ἀχθ[ῆναι, where the editors render ‘‘in order | to prevent the details being accurately known”’ : it is doubtful, however, whether the addition of ‘‘accurately’’ is required. The term, as in Phil 1°, Heb τοῦδ, may well have been borrowed from the popular philosophy of the day: cf. Epict. ii. xx. 21 λαβὼν... . κανόνας els ἐπίγνωσιν τῆς ἀληθείας.
