Satan and his fallen angels are cast out of heaven at the midpoint of the 70th week.
Revelation Chapter 12:1-17
Rev 12:1 Now a great sign appeared in heaven: a woman clothed with the sun, with the moon under her feet, and on her head a garland of twelve stars. 2 Then being with child, she cried out in labor and in pain to give birth.
3 And another sign appeared in heaven: behold, a great, fiery red dragon having seven heads and ten horns, and seven diadems on his heads. 4 His tail drew a third of the stars of heaven and threw them to the earth. And the dragon stood before the woman who was ready to give birth, to devour her Child as soon as it was born. 5 She bore a male Child who was to rule all nations with a rod of iron. And her Child was caught up to God and His throne.
6 Then the woman (Israel) fled into the wilderness, where she has a place prepared by God, that they should feed her there One Thousand Two Hundred and Sixty days.
7 And war broke out in heaven: Michael and his angels fought with the dragon; and the dragon and his angels fought, 8 but they did not prevail, nor was a place found for them in heaven any longer. 9 So the great dragon was cast out, that serpent of old, called the Devil and Satan, who deceives the whole world; he was cast to the earth, and his angels were cast out with him.
10 Then I heard a loud voice saying in heaven, “Now salvation, and strength, and the kingdom of our God, and the power of His Christ have come, for the accuser of our brethren, who accused them before our God day and night, has been cast down. 11 And they overcame him by the blood of the Lamb and by the word of their testimony, and they did not love their lives to the death. 12 Therefore rejoice, O heavens, and you who dwell in them! Woe to the inhabitants of the earth and the sea! For the devil has come down to you, having great wrath, because he knows that he has a short time.”
13 Now when the dragon saw that he had been cast to the earth, he persecuted the woman who gave birth to the male Child. 14 But the woman was given two wings of a great eagle, that she might fly into the wilderness to her place, where she is nourished for a time and times and half a time, (Twelve Hundred Sixty days) from the presence of the serpent. 15 So the serpent spewed water out of his mouth like a flood after the woman, that he might cause her to be carried away by the flood. 16 But the earth helped the woman, and the earth opened its mouth and swallowed up the flood which the dragon had spewed out of his mouth. 17 And the dragon was enraged with the woman, and he went to make war with the rest of her offspring, who keep the commandments of God and have the testimony of Jesus Christ."
Daniel Chapter 12:1-13
Dan 12:1 “At that time Michael shall stand up (stand aside),
The great prince who stands watch over the sons of your people;
And there shall be a time of trouble (great tribulation),
Such as never was since there was a nation,
Even to that time.
And at that time your people shall be delivered,
Every one who is found written in the book.
Some to everlasting life,
Some to shame and everlasting contempt.
Like the brightness of the firmament,
And those who turn many to righteousness
Like the stars forever and ever.
5 Then I, Daniel, looked; and there stood two others, one on this riverbank and the other on that riverbank. 6 And one said to the man clothed in linen, who was above the waters of the river, “How long shall the fulfillment of these wonders be?”
7 Then I heard the man clothed in linen, who was above the waters of the river, when he held up his right hand and his left hand to heaven, and swore by Him who lives forever, that it shall be for a time, times, and half a time; (to the Second Coming) and when the power of the holy people has been completely shattered, all these things shall be finished.
9 And he said, “Go your way, Daniel, for the words are closed up and sealed till the time of the end. 10 Many shall be purified, made white, and refined, but the wicked shall do wickedly; and none of the wicked shall understand, but the wise shall understand. 11 “And from the time that the daily sacrifice is taken away, and the abomination of desolation is set up, there shall be one thousand two hundred and ninety days (to Armageddon). 12 Blessed is he who waits, and comes to the one thousand three hundred and thirty-five days (to the Millennium).
