Revelation 20:1-3

Darby Translation

20 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.
