"Beware of false prophets, who come to you in sheep's clothing but inwardly are ravenous wolves."  (Matthew 7:15)

"And many false prophets will arise and lead many astray... For false messiahs and false prophets will appear and produce great signs and omens, to lead astray, if possible, even the elect."   (Matthew 24:11, 24)

Lake of Fire

And the beast was captured, and with it the false prophet who had performed in its presence the signs by which he deceived those who had received the mark of the beast and those who worshiped its image. These two were thrown alive into the lake of fire that burns with sulfur. (Revelation 19:20)

And the devil who had deceived them was thrown into the lake of fire and sulfur, where the beast and the false prophet were, and they will be tormented day and night forever and ever...   Then Death and Hades were thrown into the lake of fire. This is the second death, the lake of fire; and anyone whose name was not found written in the book of life was thrown into the lake of fire.  (Revelation 20:10, 14-15)
