Revelation 12:7 "And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels, 8: And prevailed not; neither was their place found any more in heaven. 9: And the great dragon was cast out, that old serpent, called the Devil and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him."  Revelation 20:1 "And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand. 2: And he laid hold on the dragon, that old serpent, which is the Devil, and Satan, and bound him a thousand years, 3: 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 should be loosed a little season." - St. Michael the Archangel Casting Satan Into Hell by Peter Gabriel Murphy. http://hadrian6.tumblr.com_nksuq8f7xo1rqqedro1_540
