and the death and the hades were cast to the lake of the fire, this is the second death;

And death and Hell were put into the sea of fire. This is the second death, even the sea of fire.

Death and hell were thrown into the lake of fire. This is the second death, the lake of fire.

Then Death and Hades were hurled into the lake of fire. This is the Second Death – the lake of fire;

And death and hell were cast into the lake of fire - Death and Hades (hell) are here personified, as they are in the previous verse. The declaration is equivalent to the statement in 1-Corinthians 15:26; "The last enemy that shall be destroyed is death." See the notes on that passage. The idea is, that death, considered as the separation of soul and body, with all the attendant woes, will exist no more. The righteous will live forever, and the wicked will linger on in a state never to be terminated by death. The reign of Death and Hades, as such, would come to an end, and a new order of things would commence where this would be unknown. There might be what would be properly called death, but it would not be death in this form; the soul would live forever, but it would not be in that condition represented by the word ᾅδης hadēs - "hades." There would be "death" still, but a "second death differs from the first, in the fact that it is not a separation of the soul and body, but a state of "continual agony" like what the first death inflicts - like that in intensity, but not in kind" (Prof. Stuart).
This is the second death - That is, this whole process here described - the condemnation, and the final death and ruin of those whose names are "not found written in the book of life" - properly constitutes the second death. This proves that when it is said that "death and hell were cast into the lake of fire," it cannot be meant that all punishment will cease forever, and that all will be saved, for the writer goes on to describe what he calls "the second death" as still existing. See Revelation 20:15. John describes this as the second death, not because it in all respects resembles the first death, but because it has so many points of resemblance that it may be properly called "death." Death, in any form, is the penalty of law; it is attended with pain; it cuts off from hope, from friends, from enjoyment; it subjects him who dies to a much-dreaded condition, and in all these respects it was proper to call the final condition of the wicked "death" - though it would still be true that the soul would live. There is no evidence that John meant to affirm that the second death would imply an extinction of "existence." Death never does that; the word does not naturally and properly convey that idea.

And death and hell were cast into the lake - Death himself is now abolished, and the place for separate spirits no longer needful. All dead bodies and separated souls being rejoined, and no more separation of bodies and souls by death to take place, consequently the existence of these things is no farther necessary.
This is the second death - The first death consisted in the separation of the soul from the body for a season; the second death in the separation of body and soul from God for ever. The first death is that from which there may be a resurrection; the second death is that from which there can be no recovery. By the first the body is destroyed during time; by the second, body and soul are destroyed through eternity.

(26) And death and hell were cast into the lake of fire. This is the second death.
(26) The last enemy which is death shall be abolished by Christ (that he may no more make any attempt against us) (1-Corinthians 15:16) and death shall feed on the reprobate in hell for evermore, according to the righteous judgment of God, in the next verse (Revelation 20:15).

And death and hell were cast into the lake of fire,.... Death cannot be taken properly, nor hell be the place of torment, for devils and damned spirits; since that is that lake of fire, for then the sense would be, hell is cast into hell; but either by these the devil is meant, who has the power of death, and is the prince of hell, were it not that the casting of him into this lake is mentioned before in Revelation 20:10 or it denotes the destruction and abolition of death and the grave, that from henceforth they should no more have power over men, nor have any under their dominion, and in their hands; and so what has been promised will now be fully performed, Hosea 13:14 see Revelation 21:4 or rather the wicked dead, which they shall have delivered up, and will be judged and sentenced to eternal death, Revelation 20:13
this is the second death; or the destruction of the soul and body in hell, which will consist in an eternal separation of both from God, and in a continual sense of his wrath and displeasure. The Alexandrian copy and the Complutensian edition read, "this second death is the lake of fire"; and so the Arabic version, "and this is the second death, even the lake of fire"; and not much different is the Ethiopic version, "the second death, which is the fire of hell".

Death and Hades, as personified representatives of the enemies of Christ' and His Church, are said to be cast into the lake of fire to express the truth that Christ and His people shall never more die, or be in the state of disembodied spirits.
This is the second death--"the lake of fire" is added in A, B, and ANDREAS. English Version, which omits the clause, rests on inferior manuscripts. In hell the ancient form of death, which was one of the enemies destroyed by Christ, shall not continue, but a death of a far different kind reigns there, "everlasting destruction from the presence of the Lord": an abiding testimony of the victory of Christ.

And death and hades were cast into the lake of fire - That is, were abolished for ever; for neither the righteous nor the wicked were to die any more: their souls and bodies were no more to be separated. Consequently, neither death nor hades could any more have a being.
