Thematic Bible: Satan bound for one-thousand years

Then I saw an angel coming down from Heaven, with the key of the bottomless pit and a great chain in his hand. He seized the Dragon, the primeval Serpent (who is the 'Devil' or 'Satan'), and bound him in chains for a thousand years. He flung him into the bottomless pit and locked it, and set his seal upon it; that he should not deceive the nations any more, until the thousand years were ended. After that he must be let loose for a while.
