Hippolytus of Rome, on Dan 12:9

“And he said: Go, Daniel, because the words are shut up, and sealed until the appointed time.”

“"The words are closed up and sealed." For as a man cannot tell what God has prepared for the saints; for neither has eye seen nor ear heard, nor has it entered into the heart of man (to conceive) these things, into which even the saints, too, shall then eagerly desire to look; so He said to him, "For the words are sealed until the time of the end; until many shall be chosen and tried with fire." And who are they who are chosen, but those who believe the word of truth, so as to be made white thereby, and to cast off the filth of sin, and put on the heavenly, pure, and glorious Holy Spirit, in order that, when the Bridegroom comes, they may go in straightway with Him?”
