12 A great sign appeared in heaven: a woman clothed with the sun, with the moon under her feet and a crown of twelve stars on her head.2 She was pregnant and cried out in pain as she was about to give birth.3 Then another sign appeared in heaven: an enormous red dragon with seven heads and ten horns and seven crowns on its heads.4 Its tail swept a third of the stars out of the sky and flung them to the earth. The dragon stood in front of the woman who was about to give birth, so that it might devour her child the moment he was born.5 She gave birth to a son, a male child, who “will rule all the nations with an iron scepter.”[a] And her child was snatched up to God and to his throne.6 The woman fled into the wilderness to a place prepared for her by God, where she might be taken care of for 1,260 days.
The first part of the revelation 12 sign was thought to have taken place on September 23, 2017. Some speculation is that this kicked off the 7 years of the tribulation period. Making us almost half-way through the tribulation. Other, speculation is that it was a sign to show that we are in the times and that more and more prophecy is going to be quickly fulfilled.
