unspeakable—not in themselves, otherwise Paul could not have heard them; but as the explanation states, "which it is not lawful . . . to utter" [ALFORD]. They were designed for Paul's own consolation, and not for communication to others. Some heavenly words are communicable (Exodus 34:6; Isaiah 6:3). These were not so. Paul had not the power adequately to utter; nor if he had, would he have been permitted; nor would earthly men comprehend them (John 3:12; I Corinthians 2:9). A man may hear and know more than he can speak.
