A.T. Robertson Commentary 2 Corinthians 12:1

"I must needs glory, though it is not expedient; but I will come to visions and revelations of the Lord." — 2 Corinthians 12:1 (ASV)

I must needs glory (καυχασθα δε). This is the reading of B L Latin Syriac, but Aleph D Bohairic have δε while K M read δη. The first is probably correct. He must go on with the glorying already begun, foolish as it is, though it is not expedient (ου συμφερον).

Visions (οπτασιας). Late word from οπταζω. See on Lu 1:22; Acts 26:19.

Revelations of the Lord (αποκαλυψεις Κυριου). Unveilings (from αποκαλυπτω as in Re 1:1). See on 2 Thessalonians 1:7; 1 Corinthians 1:7; 14:26. Paul had both repeated visions of Christ (Acts 9:3; Acts 16:9; Acts 18:9; Acts 22:17; 27:23f.) and revelations. He claimed to speak by direct revelation (1 Corinthians 11:23; 1 Corinthians 15:3; Galatians 1:12; Ephesians 3:3, etc.).
