SEV Biblia, Chapter 20:14
Y el infierno y la muerte fueron lanzados en el lago de fuego. Esta es la muerte segunda.
Clarke's Bible Commentary - Revelation 20:14
Verse 14. 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.
John Gill's Bible Commentary
Ver. 14. And death and hell were cast into the lake of fire , etc.] 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 1 Corinthians 15:26) (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.
Matthew Henry Commentary
Verses 11-15 - After the events just foretold, the end will speedily come; and ther is no mention of any thing else, before the appearing of Christ to judge the world. This will be the great day: the Judge, the Lord Jesu Christ, will then put on majesty and terror. The persons to be judge are the dead, small and great; young and old, low and high, poor an rich. None are so mean, but they have some talents to account for; an none so great, as to avoid having to account for them. Not only thos alive at the coming of Christ, but all the dead. There is a book of remembrance both for good and bad: and the book of the sinner' conscience, though formerly secret, will then be opened. Every man wil recollect all his past actions, though he had long forgotten many of them. Another book shall be opened, the book of the Scriptures, the rule of life; it represents the Lord's knowledge of his people, and his declaring their repentance, faith, and good works; showing the blessings of the new covenant. By their works men shall be justified of condemned; he will try their principles by their practices. Thos justified and acquitted by the gospel, shall be justified and acquitte by the Judge, and shall enter into eternal life, having nothing more to fear from death, or hell, or wicked men; for these are all destroye together. This is the second death; it is the final separation of sinners from God. Let it be our great concern to see whether our Bible justify or condemn us now; for Christ will judge the secrets of all me according to the gospel. Who shall dwell with devouring flames __________________________________________________________________
