Revelation 12:3-9

Then I witnessed in heaven another significant event. I saw a large red dragon with seven heads and ten horns, with seven crowns on his heads. His tail swept away one-third of the stars in the sky, and he threw them to the earth. He stood in front of the woman as she was about to give birth, ready to devour her baby as soon as it was born. She gave birth to a son who was to rule all nations with an iron rod. And her child was snatched away from the dragon and was caught up to God and to his throne. And the woman fled into the wilderness, where God had prepared a place to care for her for 1,260 days. Then there was war in heaven. Michael and his angels fought against the dragon and his angels. And the dragon lost the battle, and he and his angels were forced out of heaven. This great dragon—the ancient serpent called the devil, or Satan, the one deceiving the whole world—was thrown down to the earth with all his angels.
