“7 And there was war in Heaven (pertains to the “Mystery of God” being finished [10:7]): Michael and his Angels fought against the dragon; and the dragon fought and his Angels (this pertains to Satan and all the Angels who followed him being cast out of Heaven, which will take place at the midpoint of the Great Tribulation; why the Lord has allowed Satan and his minions to remain in Heaven all of this time, we aren’t told; it is a “Mystery,” but it will now be finished),
8 And prevailed not (Satan will then be defeated; incidentally, it is not Satan who instigates this war, but rather the Archangel Michael at the Command of God); neither was their place found any more in Heaven (joins with the close of the Book of Revelation, where the Evil One has no more place on Earth as well, but rather the place of torment forever and ever [20:10]).
“9 And the great dragon was cast out, that old serpent, called the Devil, and Satan; (he is the “old serpent” because in his first appearance in the Bible, he chose to work through a serpent; thereby, he is what the curse caused the serpent to be, wryly subtle, and treacherous), which deceives the whole world (deception is his greatest weapon; he deceives, and is himself deceived): he was cast out into the earth, and his Angels were cast out with him (pronounces the beginning of the end for this evil monster).” Rev. 12
