Hello Lady Goodnews.
After a while, I like to "agree to disagree", as I am not fond of strife.
I do not trust cross-references very much, and my study Bible does no such reference.
Usually, when quoting Rev. 12, I like to include verse 10 because it tells us what Satan is doing
today:
(Rev 12:10) And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down,
which accused them before our God day and night.
Everytime we fall short, Satan has audience with God, pointing the finger.
(Rev 12:12-14) Therefore rejoice, ye heavens, and ye that dwell in them. Woe to the inhabiters of the earth and of the sea! for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time. {13} And when the dragon saw that he was cast unto the earth, he persecuted the woman which brought forth the man child. {14} And to the woman were given two wings of a great eagle, that she might fly into the wilderness, into her place, where she is nourished
for a time, and times, and half a time, from the face of the serpent.
"...for a time, and times, and half a time,..." That's the last 3 1/2 years of the tribulation, which I believe was shortened to five months (Mark 13:20, Rev. 9:5, 10).
Rev 12 covers a particular chronology, and is called by some a
paranthetical chapter:
1. The world that then was:
a. vv. 1-3, mother Israel preparing for the birth of Messiah
b. v. 4a, Satan's first rebellion
3. v. 4b Satan's attempt to corrupt the Holy Seed
4. v. 5, the resurrection of Christ,
about 2,000 years ago.
5. v. 6, the preparation of the elect
6. vv. 7-10, war in heaven, Satan taken "out of the way"
7. v. 11, witness of the elect, especially the two witnesses
8. v. 12-17, protection for the woman, continued persecution of the elect.
