The book of Revelation is full of imagery and prophecy, which means that as we read there will be many confusing passages that Christians may disagree on and which I will not be able to cover at length here. Some see this next section as an overlap, sort of a call back to what has already been described at a different angle. The sign of the woman that gives birth to a child who will rule the nations is full of references to Psalm 2 which in turn is full messianic promises. The dragon is a reference to Satan, who sought to annihilate this promised child through Herod. The woman is later supernaturally sustained for 1260 days, which is the exact amount of time that the two witnesses were protected. Unable to harm the woman, the dragon wages war against those who keep the commands of God.
