Revelation 20:1-3

1 Then I saw an angel coming down from heaven, holding the key of the abyss and a great chain in his hand. 2 And he laid hold of the dragon, the serpent of old, who is the devil and Satan, and bound him for a thousand years; 3 and he threw him into the abyss, and shut it and sealed it over him, so that he would not deceive the nations any longer, until the thousand years were completed; after these things he must be released for a short time.
