Revelation 20:4-5

And then I saw thrones, and sitting on them were those to whom judgment [that is, the authority to act as judges] was given. And I saw the souls of those who had been beheaded because of their testimony of Jesus and because of the word of God, and those who had refused to worship the beast or his image, and had not accepted his mark on their forehead and on their hand; and they came to life and reigned with Christ for a thousand years. [Dan 7:9, 22, 27] 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.
