Rev 12:3 "And there appeared another wonder in heaven; and behold a great red dragon, having seven heads and ten horns, and seven crowns upon his heads."
Here we see Satan working through different agencies represented by a Beast.
Rev 12:7 "And there was war in heaven: Michael and his angels fought against the dragon;
Rev 12:9 " 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."
Rev 12:4 "And his tail drew the third part of the stars of heaven, and did cast them to the earth:"
Rev 12:7 "and the dragon fought and his angels,"
Rev 12:8 "And prevailed not; neither was their place found any more in heaven."
His deception was so strong that even angels living under God's government were deceived into his rebellion.
Satan and his angels now turns their attention to man.
What is man, that thou art mindful of him? and the son of man, that thou visitest him? For thou hast made him a little lower than the angels, and hast crowned him with glory and honour. (Ps 8:4-5)
