Revelation 20:2-10

2And he laid hold of the 1dragon, the serpent of old, who is the devil and Satan, and 2bound him for a thousand years; 3and he threw him into the 3abyss, and shut it and 4sealed it over him, so that he would 5not deceive the nations any longer, until the thousand years were completed; after these things he must be released for a short time.

4Then I saw 6thrones, and 7they sat on them, and 8judgment was given to them. And I saw 9the souls of those who had been beheaded because of 10their 11testimony of Jesus and because of the word of God, and those who had not 12worshiped the beast or his image, and had not received the 13mark on their forehead and on their hand; and they 14came to life and 15reigned with Christ for a thousand years. 5The rest of the dead did not come to life until the thousand years were completed. 16This is the first resurrection. 617Blessed and holy is the one who has a part in the first resurrection; over these the 18second death has no power, but they will be 19priests of God and of Christ and will 20reign with Him for a thousand years.

7When the thousand years are completed, Satan will be 21released from his prison, 8and will come out to 22deceive the nations which are in the 23four corners of the earth, 24Gog and Magog, to 25gather them together for the war; the number of them is like the 26sand of the 27seashore. 9And they 28came up on the 29broad plain of the earth and surrounded the 30camp of the 31saints and the 32beloved city, and 33fire came down from heaven and devoured them. 10And 34the devil who 35deceived them was thrown into the 36lake of fire and 37brimstone, where the 38beast and the 39false prophet are also; and they will be 40tormented day and night forever and ever.
