A.T. Robertson Commentary 2 Corinthians 12:4

"how that he was caught up into Paradise, and heard unspeakable words, which it is not lawful for a man to utter." — 2 Corinthians 12:4 (ASV)

Into Paradise (εις παραδεισον). See on Lu 23:43 for this interesting word. Paul apparently uses paradise as the equivalent of the third heaven in verse 2. Some Jews (Book of the Secrets of Enoch, chapter viii) make Paradise in the third heaven. The rabbis had various ideas (two heavens, three, seven). We need not commit Paul to any "celestial gradation" (Vincent).

Unspeakable words (αρρητα ρηματα). Old verbal adjective (α privative, ρητος from ρεω), only here in N.T.

Not lawful (ουκ εξον). Copula εστιν omitted. Hence Paul does

not give these words.
