when Babylon was overthrown by Medo-Persia around 530 BC, Babylon was NOT turned into a den for devils. it has been inhabited by different people groups populating the area even to this day by Iraqis. this invasion by Medo-Persia was a prophetic prelude to a coming "invasion" by supernatural beings from the ends of Heaven. the ancient prophets warned that this coming army is unparalleled to any that have, or will, ever plague the earth. it is this army that will be, called by God, loosed by angels, and will be the "second woe" and constitute the worst genocide in the History of Mankind leading to the destruction of 1/3 of humanity (this of course, is following the 1/4 of the world pop that was killed during the first 3.5 years of Daniel's 70th week), followed by ALL POWER IN SINGS AND LYING WONDERS TO DECEIVE [if possible] CHRISTIANS. this army is described in GREAT DETAIL in scripture presented by the KJV-(in order to keep the prophetic word connections not kept by other english translations- but i'm not going there ha ha!!...)
Jeremiah 50 The LORD hath opened his armoury, and hath brought forth the weapons of his indignation: for this is the work of the Lord GOD of hosts in the land of the Chaldeans.
Jeremiah 51 Thou art my battle axe and weapons of war: for with thee will I break in pieces the nations, and with thee will I destroy kingdoms;...
The sixth trumpet: Unleash the four angels bound in the Euphrates river:
I first began seeing this connection when God was moving me toward all these weird monster connections. It's the same creatures as Joel 2. Suddenly Centaurs came to mind. Like, he sees creatures “sitting” on horses. In Joel, the army of the horse[-like] men breath fire. But then, I saw a picture of the "mythological" Chimeras which match the description almost exactly! It totally could be creatures riding Chimeras. It's NOT tanks and helicopters I'M SURE OF THAT!!! I don't know if they come from Heaven, but I suspect so (windows in heaven/dimensional rifts) because Isa 13, and Jer 51 thoroughly describe judgment by fire, a destroying wind, a whirlwind, as when God over threw Sodom and Gomorrah. God used angels then, He will use them again. (sometimes I DO wonder if there are a difference between angels and demons, I think there is; AND, I think there is not. I mostly think there is a difference.)
the power is in their serpent tails and the fire they breathe, they move over the nations like a whirlwind.
The whirlwind of the Lord:
Joel 2 A fire devoureth before them; and behind them a flame burneth
 The appearance of them is as the appearance of horses; and as horsemen, so shall they run.
 Like the noise of chariots on the tops of mountains shall they leap, like the noise of a flame of fire that devoureth the stubble, as a strong people set in battle array.
isa 5:24 Therefore as the fire devoureth the stubble, and the flame consumeth the chaff...because they have cast away the law of the Lord of hosts, and despised the word of the Holy One of Israel (Yeshuah).
25 Therefore is the anger of the Lord kindled against his people, and he hath stretched forth his hand against them, and hath smitten them: and the hills did tremble [at the noise of the “horsemen”], and their carcases were torn in the midst of the streets. For all this his anger is not turned away, but his hand is stretched out still.
26 And he will lift up an ensign to the nations from far (not a local judgment), and will hiss unto them from the end of the earth (not local): and, behold, they shall come with speed swiftly:
Joel 2 They shall run like mighty men (Giants); they shall climb the wall like men of war; and they shall march every one on his ways, and they shall not break their ranks:
 Neither shall one thrust another; they shall walk every one in his path: and when they fall upon the sword, they shall not be wounded.
isa 5:27 None shall be weary nor stumble among them; none shall slumber nor sleep; neither shall the girdle of their loins be loosed, nor the latchet of their shoes be broken:(they don't sleep, they don't stumble, dressed in some sort of armor [Joel 2], and, apparently their shoes don't come untied-that one's sorta funny-not that death is funny though. the point is they are supernatural entities)
28 Whose arrows are sharp, and all their bows bent, their horses' hoofs shall be counted like flint, and their wheels like a whirlwind:
29 Their roaring shall be like a lion, they shall roar like young lions (faces as lions): yea, they shall roar, and lay hold of the prey, and shall carry it away safe, and none shall deliver it.
30 And in that day they shall roar against them like the roaring of the sea: and if one look unto the land, behold darkness and sorrow [and a thick darkness-Joel 2], and [1/3 of ] the light is darkened in the heavens thereof (Joel 2).
Isa 17:13 The nations shall rush (worldwide event) like the rushing of many waters: but God shall rebuke them, and they shall flee far off, and shall be chased as the chaff of the mountains before the wind, and like a rolling thing before the whirlwind.
Isa.21 The burden of the desert of the sea. As whirlwinds in the south pass through (yet it will come from the north, and from the coasts); so it cometh from the desert, from a terrible land.
... as the pangs of a woman that travaileth:
 And, behold, here cometh a chariot of men, with a couple of horsemen. And he answered and said, Babylon is fallen, is fallen; and all the graven images of her gods he hath broken unto the ground (this is the judgment of that day, but it is indistinguishable in the spiritual realm).
Isa 66 For, behold, the LORD will come with fire, and with his chariots like a whirlwind, to render his anger with fury, and his rebuke with flames of fire.
 For by fire and by his sword will the LORD plead with all flesh: and the slain of the LORD shall be many. (this time it is the Lord coming in His fiery Chariots at Armageddon-but whirlwind again has the supernatural angelic army context)
Jer 4:4 ….inhabitants of Jerusalem: lest my fury come forth like fire, and burn that none can quench it, because of the evil of your doings.
 ...for I will bring evil from the north, and a great destruction.
 The lion (it might seem like a stretch, but “lion” is also key in this study) is come up from his thicket, and the destroyer of the Gentiles is on his way; he is gone forth from his place [in the abyss] to make thy land desolate; and thy cities shall be laid waste, without an inhabitant.
 Even a full wind from those places shall come unto me:...
 Behold, he (the Destroyer) shall come up as clouds [as thick darkness on the mountains], and his chariots shall be as a whirlwind: his horses are swifter than eagles. Woe [to the inhabitants of the earth] unto us! for we are spoiled.
Behold, a whirlwind of the Lord is gone forth in fury, even a grievous whirlwind: it shall fall grievously upon the head of the wicked.
Thus saith the Lord of hosts, Behold, evil shall go forth from nation to nation (world wide event), and a great whirlwind shall be raised up from the coasts of the earth.
Behold, the whirlwind of the Lord goeth forth with fury, a continuing whirlwind: it shall fall with pain upon the head of the wicked.
It's not used exclusively throughout the bible, but in Isaiah and Jeremiah who deal mainly with the warning of Israel's captivity in Babylon, and then Babylon's final destruction, “whirlwind” is the angelic army from the ends of Heaven.
Jeremiah 50 describes the destruction of the future city of Babylon. (vs. 46) “At the noise of the taking of Babylon the earth is moved, and the cry is heard among the nations.”
Joel 2 The earth shall quake before them; the heavens shall tremble: the sun and the moon shall be dark, and the stars shall withdraw their shining:
It will never be inhabited again from generation to generation, it will become a habitation for devils, satyrs, Lylith, unclean and hateful birds, dragons, and all kinds of demonic hosts.
