A.T. Robertson Commentary 2 Corinthians 6:2

"(for he saith, At an acceptable time I hearkened unto thee, And in a day of salvation did I succor thee: behold, now is the acceptable time; behold, now is the day of salvation):" — 2 Corinthians 6:2 (ASV)

Behold, now is the acceptable time (ιδου νυν καιρος ευπροσδεκτος). Here is another "Pauline parenthesis" (Plummer) as in 5:7 by the quotation from Isa 49:8. The LXX has δεκτος (δεκτο) verbal of δεχομα, but Paul employs the double compound (ευ, προσ, δεκτος), well-received. It occurs in Aristophanes, Plutarch, inscription, etc.
