(4) And he opened the bottomless pit; and there arose a smoke out of the pit, as the smoke of a great furnace; and the sun and the air were darkened by reason of the smoke of the pit.
(4) To this is added, the smoke of the hellish and infernal dark spirits, darkening all things in heaven and in earth. The spiritual darkness is the cause of all disorder and confusion: For the devil at a certain time sent these spirits into his kingdom, that he might at once and with one action overthrow all things and pervert if it were possible the elect themselves. By this darkness, all spiritual light, both active as of the sun and passive as of the air which is lightened by the sun, is taken away: and this is that which goes before the spirits: it follows of the spirits themselves.
