Rev 12:1-6When the dragon saw that he had been hurled to the earth, he pursued the woman who had given birth to the male child. 14 The woman was given the two wings of a great eagle, so that she might fly to the place prepared for her in the wilderness, where she would be taken care of for a time, times and half a time, out of the serpent’s reach
In the end the mount of olives is split in two to make a way of escape for the people in Jerusalem to flee into the wilderness from the surrounding armies. Zech 14:4-5 The reign of the beast is 42 months. God has brought many in Jerusalem into the body of Christ in those days by the signs given in Rev 11. I believe it is those Israelites God is given help to in that time of the end specifically the reign of the beast.
The beast then goes after other saints as He makes war with the saints and is successful until Jesus ends tribulation and to the shock and surprise of those who have been deceived by the lies of the beast and thought Christan's were in the wrong pronounces judgment in favor of the saints of the most High.
But the earth helped the woman by opening its mouth and swallowing the river that the dragon had spewed out of his mouth. 17 Then the dragon was enraged at the woman and went off to wage war against the rest of her offspring—those who keep God’s commands and hold fast their testimony about Jesus.
John is shown a great sign in heaven as he sees a vision of a woman clothed with the sun and the moon under her feet. The sun is representative of the glory and brilliance of Gods righteousness that surrounds her and protects her. Under her feet the moon which is illustrative of eternity, light, Gods faithfulness in His Son Jesus who is the greater light of the gospel age as Jesus being the light of the world that shines in darkness, but the darkness can not comprehend the light, Psalms 72:5-7; Isaiah 2:3-5; Jeremiah 31:35-37; Isaiah 30:26-33; John 1:1-5.
The woman is symbolic of Israel and the congregation of Gods people as she wears a crown of twelve stars which represents the twelve tribes of Israel that have repented of their arrogance as they felt they deserved Gods favor, but yet kept killing the prophets God sent to them, including the very Messiah they were waiting for. This is when the times of the Gentiles began as God went to them to take Himself a people that were humbled enough to receive salvation as God had mercy on them, Matthew 23:37-39; Acts 15:14; Romans 11:25-27.
Paul also warned the Gentiles against being lifted up in pride because they had been favored by God with salvation as he explained the blindness of Israel would not last forever as when they see the Gentiles now having favor in the Lord and being grafted into the branch of Israel they repent of their sin and turn back to God being once again found in His favor, Romans Chapter 11.
The true congregation of God can be symbolized here as a mother that has all here children gathered in one place for safety which in this case is under the wings of the almighty God, Psalms 91. She cries out like a woman in labor as the pain of her persecutions has become too great to bear as she waits to be delivered from her persecutors, 2 Timothy 4:18; 2 Peter 2:9; Colossians 1:13.
The other sign John saw was a great red dragon meaning Satan. Remember, this is a vision and a sign as Satan has not yet been thrown out of heaven yet. The description of the dragon being great and red depicts its nature and character as being fierce and murderous, John 8:44. This red dragon is depicted as having seven heads, ten horns, and seven crowns upon his heads. The seven heads and ten horns refer to the original ten kingdoms of which three were subdued by the little horn of Daniel 7:8. The last kingdom which stands greater than all the others is that of a revived Roman Empire that takes control over all the ten nations who then implements a deceiving peace treaty to a world that is in great distress that will last for 3 1/2 years before the return of Christ.
