Revelation 20:14

“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 (<662010>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, (<281314>Hosea…”

“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 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…”

“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. Next: Revelation Chapter 21”

“20:14 The expression death and the grave refers to the reality of death; it is the last enemy that God will destroy (see 21:4; 1 Cor 15:26). • The lake of fire portrays the horrible end of God’s enemies who will not experience the “first resurrection” (see Rev 20:5-6; cp. Matt 25:41; Luke 16:24; Jude 1:7).”
