Ephesians 3:3

By revelation he made known unto me - Instead of εγνωρισε , he made known, εγνωρισθη , was made known, is the reading of ABCD*FG, several others, both the Syriac, Coptic, Slavonic, Vulgate, and Itala, with Clemens, Cyril, Chrysostom, Theodoret, Damascenus, and others: it is doubtless the true reading.

The apostle wishes the Ephesians to understand that it was not an opinion of his own, or a doctrine which he was taught by others, or which he had gathered from the ancient prophets; but one that came to him by immediate revelation from God, as he had informed them before in a few words, referring to what he had said Ephesians 1:9-12 .
