The DEVIL, who deceived them, was cast into the lake of fire and brimstone where the BEAST and the FALSE PROPHET are. And they will be tormented day and night forever and ever. Revelation 20:10

THEN DEATH AND HADES were cast into the lake of fire. This is the second death. And anyone not found written in the Book of Life was cast into the lake of fire. Revelation 20:14-15
