'Dragon' in the Bible

And another marvel was seen in Heaven--a great fiery-red Dragon, with seven heads and ten horns; and on his heads were seven kingly crowns.

His tail was drawing after it a third part of the stars of Heaven, and it dashed them to the ground. And in front of the woman who was about to become a mother, the Dragon was standing in order to devour the child as soon as it was born.

And war broke out in Heaven, Michael and his angels engaging in battle with the Dragon.

The Dragon fought and so did his angels; but they were defeated, and there was no longer any room found for them in Heaven.

The great Dragon, the ancient serpent, he who is called 'the Devil' and 'the Adversary' and leads the whole earth astray, was hurled down: he was hurled down to the earth, and his angels were hurled down with him.

And when the Dragon saw that he was hurled down to the earth, he went in pursuit of the woman who had given birth to the male child.

But the earth came to the woman's help: it opened its mouth and drank up the river which the Dragon had poured from his mouth.

This made the Dragon furiously angry with the woman, and he went elsewhere to make war upon her other children--those who keep God's commandments and hold fast to the testimony of Jesus.

The Wild Beast which I saw resembled a leopard, and had feet like the feet of a bear, and his mouth was like the mouth of a lion; and it was to the Dragon that he owed his power and his throne and his wide dominion.

And they offered worship to the Dragon, because it was to him that the Wild Beast owed his dominion; and they also offered worship to the Wild Beast, and said, "Who is there like him? And who is able to engage in battle with him?"

Then I saw another Wild Beast, coming up out of the earth. He had two horns like those of a lamb, but he spoke like a dragon.

Then I saw three foul spirits, resembling frogs, issue from the mouth of the Dragon, from the mouth of the Wild Beast, and from the mouth of the false Prophet.

He laid hold of the Dragon--the ancient serpent--who is the Devil and the Adversary, and bound him for a thousand years, and hurled him into the bottomless pit.
