I never had a comment for Rev 12:4. It is the first time it has hit me. I googled some commentary on it and I agree with this explanation. It makes perfect sense . ''When John tells us that the devils' tail drew a third of the stars of heaven and threw them to earth, he is describing the original demonic uprising against God. Satan somehow managed to convince a third of all God's angels to join him in his rebellion; these beings we now call "demons" or "fallen angels." They serve Satan and play an important role in the judgments of the Tribulation. We see here, also, the woman about to birth, and this is the birth of Jesus the Christ. Satan used Herod to try to kill Jesus the moment He was born. That was not God's plan, so Jesus was protected until the time of the cross. This also indicates here the birth of the church, which the devil has tried to devour every way he could.'' Just a tip. If you want to study Revelations look up 'th1bill's' threads on it. He went through it in detail.
