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.
Rev 20:10
At best this might support that these three are alive forever but the beast is not a person but a governmental system and cannot experience literal torment anyways. Plus, scripture uses intentional exaggerations so it may not be literal:
Isa 34:8 For it is the day of the LORD'S vengeance, and the year of recompences for the controversy of Zion.
Isa 34:9 And the streams thereof shall be turned into pitch, and the dust thereof into brimstone, and the land thereof shall become burning pitch.
Isa 34:10
It shall not be quenched night nor day; the smoke thereof shall go up for ever: from generation to generation it shall lie waste; none shall pass through it for ever and ever.
This is an intentional exaggeration and should be understood in that way just as Rev 20:10 should be.
Another example:
Exo 21:6 Then his master shall bring him unto the judges; he shall also bring him to the door, or unto the door post; and his master shall bore his ear through with an aul; and he shall
serve him for ever.
Not literally forever of course. It simply means "a long time", ie: the rest of his life, an intentional exaggeration.
Jude 1:7 Even as Sodom and Gomorrha, and the cities about them in like manner, giving themselves over to fornication, and going after strange flesh, are set forth for an example, suffering the vengeance of
eternal fire.
Sodom and Gomorrha is not still burning therefore this eternal fire does not imply the target burns forever but this fire exists eternally whether it has something to burn or not and since God is a consuming fire it makes sense that it is eternal because God is eternal. Remember that this fire isn't actual fire. The word fire is used because it's the closest way for us to have any chance to understand the destructive nature and result of this "fire".
And look at how many scriptures refute the idea of eternal life in hell fire:
"The soul that sinneth,
it shall die." Ezekiel 18:4.
"He that overcometh shall not be hurt of
the second death." Revelation 2:11
"And death and hell were cast into the lake of fire. This is
the second death. And whosoever was not found written in the book of life was cast into the lake of fire." Revelation 20:14,15.
"The earth and all the inhabitants thereof
are dissolved." Psalm 75:3.
"Let the sinners be consumed out of the earth, and let
the wicked be no more." Psalm 104:35.
"Consume them in wrath,
consume them, that they may not be." Psalm 59:13.
"The Lord preserveth all them that love him: but
all the wicked will he destroy." Psalm 145:20
"When the wicked spring as the grass, and when all the workers of iniquity do flourish;
it is that they shall be destroyed for ever: Psalm 92:7
"For, behold, the day cometh, that shall burn as an oven; and all the proud, yea, and all that do wickedly,
shall be as stubble; and the day cometh that shall
burn them up, saith the Lord of hosts, that
it shall leave them neither root nor branch." Malachi 4:1
"And the destruction of the transgressors and of the sinners shall be together, and
they that forsake the LORD shall be consumed." Isaiah 1:28
"Enter ye in at the straight gate: for wide is the fate, and broad is the way, that
leadeth to destruction, and many there be which go in thereat." Matthew 7:13
"I have seen the wicked in great power, and spreading himself like a green bay tree. Yet he passed away, and, lo, he was not: yea, I sought him, but
he could not be found." Psalm 37:35,36
He isn't found! Not "put into hell to be tormented for eternity". Scripture clearly shows the wicked being
destroyed.
The punishment for sin is death (Romans 6:23), which is also called the second death (Rev 20), and that judgement (also called damnation) is written to be eternal/everlasting (Mark 3:29, Hebrews 6:2).
