And the beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone. And the beast was taken, and - the false prophet - See the notes on Revelation 17:8, etc.
That worshipped his image - The beast has been represented as the Latin empire; the image of the beast, the popes of Rome; and the false prophet, the papal clergy.
Were cast alive into a lake of fire - Were discomfited when alive - in the zenith of their power, and destroyed with an utter destruction.
