How you have fallen from heaven, O star of the morning, son of the dawn! You have been cut down to the earth, You who have weakened the nations!
And He said to them, "I was watching Satan fall from heaven like lightning.
But you said in your heart, 'I will ascend to heaven; I will raise my throne above the stars of God, And I will sit on the mount of assembly In the recesses of the north. 'I will ascend above the heights of the clouds; I will make myself like the Most High.' "Nevertheless you will be thrust down to Sheol, To the recesses of the pit.
"Son of man, take up a lamentation over the king of Tyre and say to him, 'Thus says the Lord GOD, "You had the seal of perfection, Full of wisdom and perfect in beauty. "You were in Eden, the garden of God; Every precious stone was your covering: The ruby, the topaz and the diamond; The beryl, the onyx and the jasper; The lapis lazuli, the turquoise and the emerald; And the gold, the workmanship of your settings and sockets, Was in you. On the day that you were created They were prepared. "You were the anointed cherub who covers, And I placed you there. You were on the holy mountain of God; You walked in the midst of the stones of fire.
Now there was a day when the sons of God came to present themselves before the LORD, and Satan also came among them. The LORD said to Satan, "From where do you come?" Then Satan answered the LORD and said, "From roaming about on the earth and walking around on it."
No wonder, for even Satan disguises himself as an angel of light.
2 Corinthians 11:14
Yet in the same way these men, also by dreaming, defile the flesh, and reject authority, and revile angelic majesties. But Michael the archangel, when he disputed with the devil and argued about the body of Moses, did not dare pronounce against him a railing judgment, but said, "The Lord rebuke you!"
And there was war in heaven, Michael and his angels waging war with the dragon. The dragon and his angels waged war, and they were not strong enough, and there was no longer a place found for them in heaven. And the great dragon was thrown down, the serpent of old who is called the devil and Satan, who deceives the whole world; he was thrown down to the earth, and his angels were thrown down with him.
