Revelation 12:4, 9, 17

The dragon’s massive tail swept across the sky and dragged away a third of the stars of heaven and cast them to the earth. And the dragon crouched before the woman who was about to give birth—poised to devour the baby the moment it was born.

So the great dragon was thrown down once and for all. He was the serpent, the ancient snake called the devil, and Satan, who deceives the whole earth. He was cast down into the earth and his angels along with him.

Then the dragon became enraged at the woman and went off to make war against the remnant of her offspring who follow the commands of God and have the testimony of Jesus.
