'The Gehenna (Gey Hinnom) of the Fire', spoken of by Jesus —
The Hebrew Gei-Hinnom in the Jewish Bible invokes the idea of burning of children at the valley by that name in Israel and Jesus uses its Greek equivalent Gehenna with the reinforcement of the idea of burning with fire. Jesus speaks of Gehenna as a place for punishment. Hades is the grave but in His parable of Lazarus and the rich man in Hades, He added that the rich man was in torments. So, Jesus speaks of punishment in the expression 'the Gehenna of the fire' and with the Hades by adding the torment clause to it.
but I say unto you, that every one who is angry with his brother shall be in danger of the judgment; and whosoever shall say to his brother, Raca, shall be in danger of the council; and whosoever shall say, Thou fool, shall be in danger of the hell [Gehenna] of fire. Matthew 5:22 ASV
And if thine eye causeth thee to stumble, pluck it out, and cast it from thee: it is good for thee to enter into life with one eye, rather than having two eyes to be cast into the hell [Gehenna] of fire. Matthew 18:9 ASV
And if your eye offend you, pluck it out: it is better for you to enter into the Kingdom of Elohiym with one eye, than having two eyes to be cast into the fire of Gey Hinnom: Mark 9:47 Cepher
And in Hades he lifted up his eyes, being in torments, and seeth Abraham afar off, and Lazarus in his bosom. Luke 16:23 ASV
The Book of revelation speaks instead of the lake of fire where torment is going on day and night, for ever and ever.
Satan says that it cannot be. We may not take the word of Satan for it to slack as we did when he assured Adam and Eve that, 'You will not die'.

And if thy foot offend thee, cut it off: it is better for thee to enter halt into life, than having two feet to be cast into hell [Gehenna], into the fire that never shall be quenched: Mark 9:45 KJV
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: Revelation 19:20 ASV
