“And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever.”
King James Version (KJV)
20:10 And they - All these. Shall be tormented day and night - That is, without any intermission. Strictly speaking, there is only night there: no day, no sun, no hope!
Re 20:10 And the devil that deceived them was cast into the lake of fire. This is Satan's last battle. His time has come. The great deceiver is not cast into the bottomless pit now. The lake of fire is opened, and we discover there the beast and the false prophet, but they have gone whence none ever return. There the devil is cast in and locked up to abide with his allies in wickedness forever.
