Revelation 20:5

He seized the dragon, the old serpent, who is the devil and Satan, who deceives the whole inhabited earth, and bound him for a thousand years,

and cast him into the abyss, and shut it and sealed it over him, that he should deceive the nations no more until the thousand years were finished. After this, he must be freed for a short time.

I saw thrones, and they sat on them, and judgment was given to them. I saw the souls of those who had been beheaded for the testimony of Jesus and for the word of God, and such as didn’t worship the beast nor his image, and didn’t receive the mark on their forehead and on their hand. They lived and reigned with Christ for a thousand years.

Blessed and holy is he who has part in the first resurrection. Over these, the second death has no power, but they will be priests of God and of Christ, and will reign with him one thousand years.

And after the thousand years, Satan will be released from his prison

and he will come out to deceive the nations which are in the four corners of the earth, Gog and Magog, to gather them together to the war, whose number is as the sand of the sea.
