17:15 The light that surrounds the angel fills the cell, but does not rouse the apostle. Not until he feels the touch of the angel's hand and hears a voice saying, "Arise up quickly," does he awaken sufficiently to see his cell illuminated by the light of heaven, and an angel of great glory standing before him. Mechanically he obeys the word spoken to him, and as in rising he lifts his hands he is dimly conscious that the chains have fallen from his wrists.
