Revelation 20:1-3

21st Century King James Version

20 And I saw an angel come down from Heaven, having the key to the bottomless pit and a great chain in his hand.

² And he laid hold on the dragon, that serpent of old, who is the devil and Satan, and bound him for a thousand years.

³ And he cast him into the bottomless pit, and shut him up and set a seal upon him, that he should deceive the nations no more till the thousand years should be fulfilled; and after that he must be loosed a little season.
