The only verse that "might" say someone is tormented forever in hell fire is that one verse and it only says it happens to the devil only but two other verses say the devil will be destroyed and no longer exist and since there are no contradictions in the bible we have to recognize that even the forever and ever regarding the devil is a figure of speech and not literal.
"And they will go away into
eternal punishment, but the righteous into
eternal life.”
However you interpret the word 'eternal' in the verse above, must retain the same meaning for both the wicked and the righteous.
Since we know that eternal life will be never ending existence in the kingdom of God, then eternal punishment would also have to be never ending punishment. To be clear, you can't have 'eternal' for the righteous mean never ending and then have eternal mean cessation of existence for the wicked.
In addition and as I have already made clear to you, the scripture states that the wicked will have no rest, day or night and that the smoke of their torment will rise up forever and ever. There is no way to distort or circumvent the meaning of this. The words 'no rest day of night' and 'smoke rising up forever and ever' support the idea of on-going punishment. If you will use reasoning, in order to have no rest day or night and their smoke ascend up forever and ever, they must be existing in order to experience that.
Regarding Satan, his angels, the beast and the false prophet, their punishment will also be never ending.
"But the beast was captured along with the false prophet, who on its behalf had performed signs deceiving those who had the mark of the beast and worshiped its image. Both the beast and the false prophet were thrown alive into the fiery lake of burning sulfur."
"And the devil who had deceived them was thrown into the lake of fire and sulfur, into which the beast and the false prophet had already been thrown. There they will be tormented day and night forever and ever."
Notice in Rev.19:20 that the beast and the false prophet will be thrown into the lake of fire at the on-set of the thousand years. Then after the thousand years are over, Satan will be thrown into the same place, where the beast, the false prophet had been thrown. And all of them will be tormented day and night forever and ever. There's are those supporting words again which infers no cessation of said torment.
