'Second Death' in the Bible

Let everyone who has ears listen to what the Spirit says to the churches. Whoever conquers will not be hurt at all by the second death."'"

Blessed and holy is the man who shares in the first resurrection! Over such the second death will have no power, but they will be priests of God and Christ, and reign with Him the thousand years.

Then death and the underworld were hurled into the fiery lake, This is the second death -- the fiery lake.

But the cowards, the unfaithful, the polluted, the murderers, the sexually immoral, the practicers of magic, the worshipers of idols, and all liars will have their portion in the lake that keeps on burning with fire and brimstone. This is the second death."
