Revelation 12 describes a wide variety of eras, including Jesus' ascension and the second Rapture. This Rapture is the rescue of the Tribulation saints from the Antichrist and the False Prophet, described in Revelation 13:
The Apocalypse Rapture: End Time Prophecy in Revelation 12 and 13
That link is pushing doctrines from the false Jews.
The word 'rapture' does not come from the Greek word '
harpazo' ("caught up" in KJV). It comes from Latin
raptus, which was used for Greek manuscript
harpazo).
So when one uses the word 'rapture' in place of "caught up" in the KJV, they are actually referring to a Latin translation.
That link wrongly points to a Pope as the Antichrist. That is a doctrine that has continued down from the old Reformers who in their day, because of Catholic Church persecuting Protestants, thought the pope then was fulfilling the Antichrist for the end of this world. That didn't happen, but the false Jews still like to push that falsehood today, since the Catholic Church persecuted the Jews also back in history, and especially the secret societies which the false Jews today sit over.
God's Word points directly to the "dragon" as the coming Antichrist, and that dragon title is another name for Satan himself we are told in Revelation 12:9. Revelation 13:4-8 says the whole world will worship the "dragon", except for those who's names are written in the book of life from the foundation of the world.
Revelation 11 and Revelation 17 point directly to JERUSALEM being where the final Antichrist will show up and reign from, and will ascend out of the bottomless pit (Satan again), and kill God's two witnesses there in Jerusalem. The false Jews thus do not want you to think that, but want you to key on a pope instead of watching Jerusalem at the end.
Also, there is no such thing as a Pre-tribulational Rapture written anywhere in God's Word. Lord Jesus showed emphatically that His coming and gathering of His saints is to be AFTER... the tribulation (per Matthew 24:29-31 and Mark 13:24-27). Those men behind that false doctrine are false Jews of the "synagogue of Satan". That false doctrine was first preached in a Christian church in 1830's Great Britain. Before that, the Christian Church has always held to Jesus' coming after the tribulation, as written.
