Revelation wrote:
In the center, around the throne, were four living creatures, and they were covered with eyes, in front and in back. The first living creature was like a lion, the second was like an ox, the third had a face like a man, the fourth was like a flying eagle. Each of the four living creatures had six wings and was covered with eyes all around, even under its wings. Day and night they never stop saying:
“‘Holy, holy, holy is the Lord God Almighty,’ who was, and is, and is to come.â€
[...]
As I watched, I heard an eagle that was flying in midair call out in a loud voice: “Woe! Woe! Woe to the inhabitants of the earth, because of the trumpet blasts about to be sounded by the other three angels!â€

A great sign appeared in heaven: a woman clothed with the sun, with the moon under her feet and a crown of twelve stars on her head. She was pregnant and cried out in pain as she was about to give birth. Then another sign appeared in heaven: an enormous red dragon with seven heads and ten horns and seven crowns on its heads. Its tail swept a third of the stars out of the sky and flung them to the earth. The dragon stood in front of the woman who was about to give birth, so that it might devour her child the moment he was born. She gave birth to a son, a male child, who “will rule all the nations with an iron scepter.†And her child was snatched up to God and to his throne. The woman fled into the wilderness to a place prepared for her by God, where she might be taken care of for 1,260 days.
Then war broke out in heaven. Michael and his angels fought against the dragon, and the dragon and his angels fought back. But he was not strong enough, and they lost their place in heaven. The great dragon was hurled down—that ancient serpent called the devil, or Satan, who leads the whole world astray. He was hurled to the earth, and his angels with him.
