'Second Death' in the Bible

Let everyone who can hear listen to what the Spirit says to the churches. He who is victorious will not be hurt by the second death.'

Blessed and holy is the man who experiences the first resurrection! The second death has no power over them; they will be priests of God and the Christ, and reign with him for the thousand years.

Then death and Hades were flung into the fiery lake. This is the second death??he fiery lake.

But the cowardly, unfaithful, and polluted??urderers, immoral people, those who practice magic or idolatry, and all liars will find themselves in the burning lake of fire and brimstone. This is the second death."
