Satan

 > > 13 When the dragon saw that he had been hurled to the earth, he pursued the woman who had given birth to the male child. 14 The woman was given the two wings of a great eagle, so that she might fly to the place prepared for her in the wilderness, where she would be taken care of for a time, times and half a time, out of the serpent’s reach. 15 Then from his mouth the serpent spewed water like a river, to overtake the woman and sweep her away with the torrent.
