'Lake of Fire' in the Bible

And the beast was taken, and with him the false prophet that wrought the signs in his sight, wherewith he deceived them that had received the mark of the beast and them that worshipped his image: they two were cast alive into the lake of fire that burneth with brimstone:

And the devil that deceived them was cast into the lake of fire and brimstone, where are also the beast and the false prophet; and they shall be tormented day and night for ever and ever.

And death and Hades were cast into the lake of fire. This is the second death, even the lake of fire.

And if any was not found written in the book of life, he was cast into the lake of fire.
