Barnes' Notes
Then was the secret revealed ... - To wit, the dream and the interpretation. The thing which had been "hidden" was disclosed. We may suppose that this occurred after a suitable time had been given to prayer.
In a night vision - A representation made to him at night, but whether when he was asleep or awake does not appear. Compare the notes at Daniel 1:17; Isaiah 1:1; Job 4:13; Job 33:15.
Then Daniel blessed the God of heaven - Nothing would be more natural than that he should burst forth in a song of grateful praise for disclosing a secret by means of which his life, and the lives of his companions, would be preserved, and by which such signal honor would redound to God himself, as alone able to reveal coming events.
