I have been intrigues by this as well. I have pasted my own study. Maybe these verses may help a little.
Ezekiel 10:9-14 (spectacular)
9 I looked, and I saw beside the cherubim four wheels, one beside each of the cherubim; the wheels sparkled like topaz. 10 As for their appearance, the four of them looked alike; each was like a wheel intersecting a wheel. 11 As they moved, they would go in any one of the four directions the cherubim faced; the wheels did not turn about as the cherubim went. The cherubim went in whatever direction the head faced, without turning as they went. 12 Their entire bodies, including their backs, their hands and their wings, were completely full of eyes, as were their four wheels. 13 I heard the wheels being called “the whirling wheels.” 14 Each of the cherubim had four faces: One face was that of a cherub, the second the face of a human being, the third the face of a lion, and the fourth the face of an eagle.
Ezekiel 28:11-19 (Young's Literal Translation)
11And there is a word of Jehovah unto me, saying:
12`Son of man, lift up a lamentation for the king of Tyre, And thou hast said to him: Thus said the Lord Jehovah: Thou art sealing up a measurement, Full of wisdom, and perfect in beauty.
13In Eden, the garden of God, thou hast been, Every precious stone thy covering, Ruby, topaz, and diamond, beryl, onyx, and jasper, Sapphire, emerald, and carbuncle, and gold, The workmanship of thy tabrets (tambourines), and of thy pipes, In thee in the day of thy being produced, have been prepared. (built in organs/instruments of praise? His job/purpose?)
14Thou [art] an anointed cherub who is covering, And I have set thee in the holy mount, God thou hast been, In the midst of stones of fire thou hast walked up and down.
15Perfect [art] thou in thy ways, From the day of thy being produced, Till perversity (sexual?) hath been found in thee.
16By the abundance of thy merchandise They have filled thy midst with violence, And thou dost sin, And I thrust thee from the mount of God, And I destroy thee, O covering cherub, From the midst of the stones of fire.
17High hath been thy heart, because of thy beauty, Thou hast corrupted thy wisdom because of thy brightness, On the earth I have cast thee, Before kings I have set thee, to look on thee,
18From the abundance of thy iniquity, By the perversity of thy traffic, Thou hast polluted thy sanctuaries, And I bring forth fire from thy midst, It hath devoured thee, And I make thee become ashes on the earth, Before the eyes of all beholding thee.
19All knowing thee among the peoples Have been astonished at thee, Wastes thou hast been, and thou art not -- to the age.
while the morning stars sang together
and all the angels shouted for joy?
6Now there was a day when the sons of God came to present themselves before the LORD, and Satan also came among them.
Prerequisites to the flood?
4 The Nephilim were on the earth in those days—and also afterward—when the sons of God went to the daughters of men and had children by them. They were the heroes of old, men of renown.
5 Though you already know all this, I want to remind you that the Lord delivered his people out of Egypt, but later destroyed those who did not believe. 6 And the angels who did not keep their positions of authority but abandoned their own home—these he has kept in darkness, bound with everlasting chains for judgment on the great Day. 7 In a similar way, Sodom and Gomorrah and the surrounding towns gave themselves up to sexual immorality and perversion. They serve as an example of those who suffer the punishment of eternal fire.
Genesis 6:1-9 (Young's Literal Translation)
1And it cometh to pass that mankind have begun to multiply on the face of the ground, and daughters have been born to them,
2and sons of God see the daughters of men that they [are] fair, and they take to themselves women of all whom they have chosen.
3And Jehovah saith, `My Spirit doth not strive in man -- to the age; in their erring they [are] flesh:' and his days have been an hundred and twenty years.
4The fallen ones were in the earth in those days, and even afterwards when sons of God come in unto daughters of men, and they have borne to them -- they [are] the heroes, who, from of old, [are] the men of name.
5And Jehovah seeth that abundant [is] the wickedness of man in the earth, and every imagination of the thoughts of his heart only evil all the day;
6and Jehovah repenteth that He hath made man in the earth, and He grieveth Himself -- unto His heart.
7And Jehovah saith, `I wipe away man whom I have prepared from off the face of the ground, from man unto beast, unto creeping thing, and unto fowl of the heavens, for I have repented that I have made them.'
8And Noah found grace in the eyes of Jehovah.
9These [are] births of Noah: Noah [is] a righteous man; perfect he hath been among his generations; with God hath Noah walked habitually.
(one commentator – indicated this may mean that Noah’s dna/geneaology was unpolluted, undefiled – his ancestors had not intermarried with these angels)
The Israelites prepare to invade the promised land
22 They went up through the Negev and came to Hebron, where Ahiman, Sheshai and Talmai, the descendants of Anak, lived. (Hebron had been built seven years before Zoan in Egypt.) 23 When they reached the Valley of Eshcol, they cut off a branch bearing a single cluster of grapes. Two of them carried it on a pole between them, along with some pomegranates and figs. 24 That place was called the Valley of Eshcol because of the cluster of grapes the Israelites cut off there. 25 At the end of forty days they returned from exploring the land.
26 They came back to Moses and Aaron and the whole Israelite community at Kadesh in the Desert of Paran. There they reported to them and to the whole assembly and showed them the fruit of the land. 27 They gave Moses this account: “We went into the land to which you sent us, and it does flow with milk and honey! Here is its fruit. 28 But the people who live there are powerful, and the cities are fortified and very large. We even saw descendants of Anak there.
Numbers 13:33 *****************
33 We saw the Nephilim there (the descendants of Anak come from the Nephilim). We seemed like grasshoppers in our own eyes, and we looked the same to them.”
28 Where can we go? Our brothers have made us lose heart. They say, ‘The people are stronger and taller than we are; the cities are large, with walls up to the sky. We even saw the Anakites there.’”
10 (The Emites used to live there—a people strong and numerous, and as tall as the Anakites. 11 Like the Anakites, they too were considered Rephaites, but the Moabites called them Emites.
21 They were a people strong and numerous, and as tall as the Anakites. The LORD destroyed them from before the Ammonites, who drove them out and settled in their place.
2 The people are strong and tall—Anakites! You know about them and have heard it said: “Who can stand up against the Anakites?” So who were the Israelites to fight when they crossed the Jordan River? Were these fallen satanic angels?
12 For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms.God delivers the Anakites into Joshua’s hand and they are destroyed.
21 At that time Joshua went and destroyed the Anakites from the hill country: from Hebron, Debir and Anab, from all the hill country of Judah, and from all the hill country of Israel. Joshua totally destroyed them and their towns. 22 No Anakites were left in Israelite territory; only in Gaza, Gath and Ashdod did any survive.
12 Now give me this hill country that the LORD promised me that day. You yourself heard then that the Anakites were there and their cities were large and fortified, but, the LORD helping me, I will drive them out just as he said.”
13 Then Joshua blessed Caleb son of Jephunneh and gave him Hebron as his inheritance. 14 So Hebron has belonged to Caleb son of Jephunneh the Kenizzite ever since, because he followed the LORD, the God of Israel, wholeheartedly. 15 (Hebron used to be called Kiriath Arba after Arba, who was the greatest man among the Anakites.) God’s judgement on satan and his minions
12 How you have fallen from heaven,
O morning star, son of the dawn!
You have been cast down to the earth,
you who once laid low the nations!
13 You said in your heart,
“I will ascend to heaven;
I will raise my throne
above the stars of God;
I will sit enthroned on the mount of assembly,
on the utmost heights of the sacred mountain.
14 I will ascend above the tops of the clouds;
I will make myself like the Most High.”
15 But you are brought down to the grave,
to the depths of the pit.
16 Those who see you stare at you,
they ponder your fate:
“Is this the man who shook the earth
and made kingdoms tremble,
17 the man who made the world a desert,
who overthrew its cities
2 Peter 2:4-5
4 For if God did not spare angels when they sinned, but sent them to hell, putting them into gloomy dungeons to be held for judgment; 5 if he did not spare the ancient world when he brought the flood on its ungodly people, but protected Noah, a preacher of righteousness, and seven others;
3 Then another sign appeared in heaven: an enormous red dragon with seven heads and ten horns and seven crowns on his heads. 4 His 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 he might devour her child the moment it was born. 5 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. 6 The woman fled into the desert to a place prepared for her by God, where she might be taken care of for 1,260 days.
7 And there was war in heaven. Michael and his angels fought against the dragon, and the dragon and his angels fought back. 8 But he was not strong enough, and they lost their place in heaven. 9 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.
He replied, “I saw Satan fall like lightning from heaven.
2 Corinthians 11:14
And no wonder, for Satan himself masquerades as an angel of light.
1 Now the serpent was more crafty than any of the wild animals the LORD God had made. He said to the woman, “Did God really say, ‘You must not eat from any tree in the garden’?”
2 The woman said to the serpent, “We may eat fruit from the trees in the garden, 3 but God did say, ‘You must not eat fruit from the tree that is in the middle of the garden, and you must not touch it, or you will die.’”
4 “You will not surely die,” the serpent said to the woman. 5 “For God knows that when you eat of it your eyes will be opened, and you will be like God, knowing good and evil.”
6 When the woman saw that the fruit of the tree was good for food and pleasing to the eye, and also desirable for gaining wisdom, she took some and ate it. She also gave some to her husband, who was with her, and he ate it. 7 Then the eyes of both of them were opened, and they realized they were naked; so they sewed fig leaves together and made coverings for themselves.
8 Then the man and his wife heard the sound of the LORD God as he was walking in the garden in the cool of the day, and they hid from the LORD God among the trees of the garden. 9 But the LORD God called to the man, “Where are you?”
10 He answered, “I heard you in the garden, and I was afraid because I was naked; so I hid.”
11 And he said, “Who told you that you were naked? Have you eaten from the tree that I commanded you not to eat from?”
12 The man said, “The woman you put here with me—she gave me some fruit from the tree, and I ate it.”
13 Then the LORD God said to the woman, “What is this you have done?”
The woman said, “The serpent deceived me, and I ate.”
14 So the LORD God said to the serpent, “Because you have done this,
“Cursed are you above all the livestock
and all the wild animals!
You will crawl on your belly
and you will eat dust
all the days of your life.
15 And I will put enmity
between you and the woman,
and between your offspring and hers;
he will crush your head,
and you will strike his heel.”
16 To the woman he said,
“I will greatly increase your pains in childbearing;
with pain you will give birth to children.
Your desire will be for your husband,
and he will rule over you.”
17 To Adam he said, “Because you listened to your wife and ate from the tree about which I commanded you, ‘You must not eat of it,’
“Cursed is the ground because of you;
through painful toil you will eat of it
all the days of your life.
18 It will produce thorns and thistles for you,
and you will eat the plants of the field.
19 By the sweat of your brow
you will eat your food
until you return to the ground,
since from it you were taken;
for dust you are
and to dust you will return.”
20 Adam named his wife Eve, because she would become the mother of all the living.
21 The LORD God made garments of skin for Adam and his wife and clothed them. 22 And the LORD God said, “The man has now become like one of us, knowing good and evil. He must not be allowed to reach out his hand and take also from the tree of life and eat, and live forever.” 23 So the LORD God banished him from the Garden of Eden to work the ground from which he had been taken. 24 After he drove the man out, he placed on the east side of the Garden of Eden cherubim and a flaming sword flashing back and forth to guard the way to the tree of life.
1 Peter 5:8
Be self-controlled and alert. Your enemy the devil prowls around like a roaring lion looking for someone to devour.
“Then he will say to those on his left, ‘Depart from me, you who are cursed, into the eternal fire prepared for the devil and his angels.
And the devil, who deceived them, was thrown into the lake of burning sulfur, where the beast and the false prophet had been thrown. They will be tormented day and night forever and ever
I am simply encouraged to remember to things:
• We were made to praise Him and failure to move towards God’s purposes in our lives leads to destruction.
• Our fight is not against flesh and blood.
