Revelation 20:6, 13-15

Blessed and holy are those who share in the first resurrection. For them the second death holds no power, but they will be priests of God and of Christ and will reign with him a thousand years.

The sea gave up its dead, and death and the grave gave up their dead. And all were judged according to their deeds. Then death and the grave were thrown into the lake of fire. This lake of fire is the second death. And anyone whose name was not found recorded in the Book of Life was thrown into the lake of fire.
