When 1,000 years are over, Satan will be freed from his prison. He will go out to deceive Gog and Magog, the nations in the four corners of the earth, and gather them for war. They will be as numerous as the grains of sand on the seashore. 

       I [John] saw that they spread over the broad expanse of the earth and surrounded the camp of God’s holy people and the beloved city. Fire came from heaven and burned them up. 

           The devil, who deceived them, was thrown into the fiery lake of sulfur, where the beast and the false prophet were also thrown. They will be tortured day and night forever and ever.
