Revelation 20:1–3 (ASV 1901)

And I saw an angel coming down out of heaven, having the key of the abyss and a great chain in his hand. 2And he laid hold on the dragon, the old serpent, which is the Devil and Satan, and bound him for a thousand years, 3and cast him into the abyss, and shut it, and sealed it over him, that he should deceive the nations no more, until the thousand years should be finished: after this he must be loosed for a little time.
