21:33 Acceptable to the gravel of Cocytus: The Hebrew word, which St. Jerome has here rendered by the name Cocytus, (which the poets represent as a river in hell,) signifies a valley or a torrent: and in this place, is taken for the low region of death and hell: which willingly, as it were, receives the wicked at their death: who are ushered in by innumerable others that have gone before them; and are followed by multitudes above number.
