Satan Bound

20 ^[a]And then I saw an angel descending from heaven, holding the key of the abyss (the bottomless pit) and a great chain was in his hand. ² And he overpowered and laid hold of the dragon, that old serpent [of primeval times], who is the devil and Satan, and bound him [securely] for a thousand years (a millennium);^{(A) 3} and the angel hurled him into the abyss, and closed it and sealed it above him [preventing his escape or rescue], so that he would no longer deceive and seduce the nations, until the thousand years were at an end. After these things he must be liberated for a short time.

The Millennial Reign

⁴ 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.^{(B) 5} 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. ^6 [b]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.^(C)
