"forces of evil in the heavenly realms"
Revelation 12:13-14 When the dragon saw that he had been hurled to the earth, he pursued the woman who had given birth to the male child. The woman was given the two wings of a great eagle, so that she might fly to the place prepared for her in the desert, where she would be taken care of for a time, times and half a time, out of the serpent's reach.
Ephesians 6:12 For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms.
The Dragon and the Serpent are the same, Shape shifting is another form of lying even looking like an angel of light.
He seized the dragon, that ancient serpent, who is the devil, or Satan, and bound him for a thousand years.
