Hell is a place of eternal fire and punishment
Unquenchable Fire
Matt. 3:12 "And His winnowing fork is in His hand, and He will thoroughly clear His threshing floor; and He will gather His wheat into the barn, but He will burn up the chaff with unquenchable fire."
Fiery Hell
Matt. 5:22, "whoever shall say, 'You fool,' shall be guilty enough to go into the fiery hell." See also, Matt. 5:29,30.
Fiery Hell
Matt. 18:8-9, "And if your hand or your foot causes you to stumble, cut it off and throw it from you; it is better for you to enter life crippled or lame, than having two hands or two feet, to be cast into the eternal fire. 9 "And if your eye causes you to stumble, pluck it out, and throw it from you. It is better for you to enter life with one eye, than having two eyes, to be cast into the fiery hell."
Eternal Fire
Matt. 25:41, "Then He will also say to those on His left, 'Depart from Me, accursed ones, into the eternal fire which has been prepared for the devil and his angels.
Eternal Punishment
Matt. 25:46, "And these will go away into eternal punishment, but the righteous into eternal life."
The word "eternal" in both places is "aionios" which means 1) without beginning and end, that which always has been and always will be; 2) without beginning; 3) without end, never to cease, everlasting. The word "punishment" is the word "kolasis" and it means "to punish, with the implication of resulting severe suffering - 'to punish, punishment.'"5
Eternal Fire
Jude 7, "Just as Sodom and Gomorrah and the cities around them, since they in the same way as these indulged in gross immorality and went after strange flesh, are exhibited as an example, in undergoing the punishment of eternal fire."
Thrown into the lake of Fire
"And the devil who deceived them was thrown into the lake of fire and brimstone, where the beast and the false prophet are also; and they will be tormented day and night forever and ever."
Lake of Fire
Rev. 20:15, "And if anyone's name was not found written in the book of life, he was thrown into the lake of fire."
FOREVER AND EVER
"into the age of the ages"
Translated as "forever and ever"; "forevermore"
"And a second time they said, "Hallelujah! Her smoke rises up forever and ever," (Rev. 19:3).
"And the devil who deceived them was thrown into the lake of fire and brimstone, where the beast and the false prophet are also; and they will be tormented day and night forever and ever," (Rev. 20:10).
"to whom be the glory forevermore, Amen" (Gal. 1:5)

"Now to the King eternal, immortal, invisible, the only God, be honor and glory forever and ever. Amen," (1 Tim. 1:17).
"The Lord will deliver me from every evil deed, and will bring me safely to His heavenly kingdom; to Him be the glory forever and ever. Amen," (2 Tim. 4:18).
"equip you in every good thing to do His will, working in us that which is pleasing in His sight, through Jesus Christ, to whom be the glory forever and ever. Amen," (Heb. 13:21).
"Whoever speaks, let him speak, as it were, the utterances of God; whoever serves, let him do so as by the strength which God supplies; so that in all things God may be glorified through Jesus Christ, to whom belongs the glory and dominion forever and ever. Amen," (1 Pet. 4:11).
"and He has made us to be a kingdom, priests to His God and Father; to Him be the glory and the dominion forever and ever. Amen," (Rev. 1:6).
"and the living One; and I was dead, and behold, I am alive forevermore, and I have the keys of death and of Hades," (Rev. 1:18).
"And when the living creatures give glory and honor and thanks to Him who sits on the throne, to Him who lives forever and ever," (Rev. 4:9).
"the twenty-four elders will fall down before Him who sits on the throne, and will worship Him who lives forever and ever, and will cast their crowns before the throne," (Rev. 4:10).
"And every created thing which is in heaven and on the earth and under the earth and on the sea, and all things in them, I heard saying, "To Him who sits on the throne, and to the Lamb, be blessing and honor and glory and dominion forever and ever," (Rev. 5:13).

Clearly, the phrase "forever and ever" is a correct translation of the Greek ""eis tous aionas ton aionon -- forever and ever" Every instance of the phrase shows eternality.
But, a word of caution. The Universalist may say that Rev. 19.3 is not eternal because it is the description of smoke from the City of Babylon. But, the judgment that is cast upon her is only the beginning of the eternal punishment of the wicked, indicated in the statement that the smoke from her goes up forever and ever.
The phrase is always speaking of eternal duration.
Universalism is incorrect because not all will be saved because:
"And the devil who deceived them was thrown into the lake of fire and brimstone, where the beast and the false prophet are also; and they will be tormented day and night forever and ever," (Rev. 20:10).
