Revelation 20:1–3 (DARBY)

1  And I saw an angel descending from the heaven, having the key of the abyss, and a great chain in his hand. 2  And he laid hold of the dragon, the ancient serpent who is the devil and Satan, and bound him a thousand years, 3  and cast him into the abyss, and shut it and sealed it over him, that he should not any more deceive the nations until the thousand years were completed; after these things he must be loosed for a little time.
