Moulton & Milligan — Vocabulary of the Greek NT
σύνεσις in its wider sense ‘‘intelligence,’’ “ἢ understanding,” as in Lk 21’, is seen in such a passage as OG/S 323° (B.C. 159138) συνέσει kal παιδείαι προάγων. For its more ‘‘ critical” aspect as distinguished from σοφία, the apprehension of general principles, see Abbott 7CC ad Col 13. ‘The noun > in the Andanian mystery inser. Sy//% “ occurs = ‘‘ decree’ 73012 (B.C. 92) σύνεσιν ἀνενεγκάντω els TO πρυτανεῖον.
