And I saw an angel coming down from heaven, having the key of the bottomless pit, and a great chain in his hand. And he laid hold on the dragon the old serpent, which is the devil and Satan, and bound him for a thousand years. And he cast him into the bottomless pit, and shut him up, and set a seal upon him, that he should no more seduce the nations, till the thousand years be finished. And after that, he must be loosed a little time.
