And I saw an angel come down from heaven,
having the key of the bottomless pit
and a great chain in his hand.
And he laid hold on the dragon,
that old serpent,
which is the Devil, and Satan,
and bound him a thousand years,
And 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.
Revelation 20:1-3
