'First Resurrection' in the Bible

The rest of the dead [the non-believers] did not come to life again until the thousand years were completed. This is the first resurrection.

Blessed (happy, prosperous, to be admired) and holy is the person who takes part in the first resurrection; over these the second death [which is eternal separation from God, the lake of fire] has no power or authority, but they will be priests of God and of Christ and they will reign with Him a thousand years.
