Isaiah 6:2
    Seraphim were stationed above; each of them had six wings: with two they veiled their faces, with two they veiled their feet, and with two they hovered aloft.

Isaiah 6:6
    Then one of the seraphim flew to me, holding an ember which he had taken with tongs from the altar.

Ezekiel 1:13
    In among the living creatures something like burning coals of fire could be seen; they seemed like torches, moving to and fro among the living creatures. The fire gleamed, and from it came forth flashes of lightning.

Satan, a fallen Seraph

Genesis 3:1-15
    Now the serpent was the most cunning of all the animals that the LORD God had made. The serpent asked the woman, "Did God really tell you not to eat from any of the trees in the garden?" [2] The woman answered the serpent: "We may eat of the fruit of the trees in the garden; [3] it is only about the fruit of the tree in the middle of the garden that God said, 'You shall not eat it or even touch it, lest you die.' " [4] But the serpent said to the woman: "You certainly will not die! [5] No, God knows well that the moment you eat of it your eyes will be opened and you will be like gods who know what is good and what is bad."

Genesis 3:14-15
    Then the LORD God said to the serpent:
    "Because you have done this, you shall be banned
        from all the animals
        and from all the wild creatures;
    On your belly shall you crawl,
        and dirt shall you eat
        all the days of your life.
    [15] I will put enmity between you and the woman,
        and between your offspring and hers;
    He will strike at your head,
        while you strike at his heel."

Rev. 12:3-4
   [3] Another sign appeared in the sky; it was a huge red dragon, with seven heads and ten horns, and on its heads were seven diadems. [4] Its tail swept away a third of the stars in the sky and hurled them down to the earth. Then the dragon stood before the woman about to give birth, to devour her child when she gave birth.

Rev. 12:7-9
    [7] Then war broke out in heaven; Michael and his angels battled against the dragon. The dragon and its angels fought back, [8] but they did not prevail and there was no longer any place for them in heaven. [9] The huge dragon, the ancient serpent, who is called the Devil and Satan, who deceived the whole world, was thrown down to earth, and its angels were thrown down with it.

Rev. 12:12-13
    [12] Therefore, rejoice, you heavens, and you who dwell in them. But woe to you, earth and sea, for the Devil has come down to you in great fury, for he knows he has but a short time."
    [13] When the dragon saw that it had been thrown down to the earth, it pursued the woman who had given birth to the male child.

Rev. 12:15
   The serpent, however, spewed a torrent of water out of his mouth after the woman to sweep her away with the current.

Rev. 12:17
    Then the dragon became angry with the woman and went off to wage war against the rest of her offspring, those who keep God's commandments and bear witness to Jesus.
