Revelation 20:1-3

Revised Geneva Translation

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 took the dragon, that old serpent, which is the devil and Satan. And he bound him for a thousand years;

³ and cast him into the bottomless pit. And he shut him up and sealed the door upon him - so that he would deceive the people no more - till the thousand years were completed. For after that, he must be let loose for a little season.
