'Dragon' in the Bible
Then another sign appeared in heaven: a huge red dragon that had seven heads and ten horns, and on its heads were seven diadem crowns.
Now the dragon's tail swept away a third of the stars in heaven and hurled them to the earth. Then the dragon stood before the woman who was about to give birth, so that he might devour her child as soon as it was born.
Then war broke out in heaven: Michael and his angels fought against the dragon, and the dragon and his angels fought back.
But the dragon was not strong enough to prevail, so there was no longer any place left in heaven for him and his angels.
So that huge dragon -- the ancient serpent, the one called the devil and Satan, who deceives the whole world -- was thrown down to the earth, and his angels along with him.
Now when the dragon realized that he had been thrown down to the earth, he pursued the woman who had given birth to the male child.
but the earth came to her rescue; the ground opened up and swallowed the river that the dragon had spewed from his mouth.
So the dragon became enraged at the woman and went away to make war on the rest of her children, those who keep God's commandments and hold to the testimony about Jesus. And the dragon stood on the sand of the seashore.
Now the beast that I saw was like a leopard, but its feet were like a bear's, and its mouth was like a lion's mouth. The dragon gave the beast his power, his throne, and great authority to rule.
they worshiped the dragon because he had given ruling authority to the beast, and they worshiped the beast too, saying: "Who is like the beast?" and "Who is able to make war against him?"
Then I saw another beast coming up from the earth. He had two horns like a lamb, but was speaking like a dragon.
Then I saw three unclean spirits that looked like frogs coming out of the mouth of the dragon, out of the mouth of the beast, and out of the mouth of the false prophet.
He seized the dragon -- the ancient serpent, who is the devil and Satan -- and tied him up for a thousand years.
