Revelation 20:5-7

Living Bible

⁵ This is the First Resurrection. (The rest of the dead did not come back to life until the thousand years had ended.) ⁶ Blessed and holy are those who share in the First Resurrection. For them the Second Death holds no terrors, for they will be priests of God and of Christ, and shall reign with him a thousand years.

⁷ When the thousand years end, Satan will be let out of his prison.
