Jerusalem which is above is free and she is the mother of us all:
Revelation 12:1-5 (YLT)
1And a great sign was seen in the heaven, a woman arrayed with the sun, and the moon under her feet, and upon her head a crown of twelve stars, 2and being with child she doth cry out, travailing and pained to bring forth.
3And there was seen another sign in the heaven, and, lo, a great red dragon, having seven heads and ten horns, and upon his head seven diadems, 4and his tail doth draw the third of the stars of the heaven, and he did cast them to the earth; and the dragon did stand before the woman who is about to bring forth, that when she may bring forth, her child he may devour 5and she brought forth a male child, who is about to rule all the nations with a rod of iron, and caught away was her child unto God and His throne,
This woman is Zion and her child that is caught up to God is the resurrected Christ.
Isaiah 66:7-9 (YLT)
7Before she is pained she hath brought forth, Before a pang cometh to her, She hath delivered a male. 8Who hath heard anything like this? Who hath seen anything like these? Is earth caused to bring forth in one day? Born is a nation at once? For she hath been pained, Zion also hath borne her sons.
9Do I bring to the birth, And not cause to bring forth? saith Jehovah, `Am not I He who is causing to beget? I have also restrained said thy God.
We get more detail in a another type and for shadow
Leviticus 12:1-4 (YLT)
1And Jehovah speaketh unto Moses, saying, 2Speak unto the sons of Israel, saying, A woman when she giveth seed, and hath born a male, then she hath been unclean seven days, according to the days of separation for her sickness she is unclean; 3and in the eighth day is the flesh of his foreskin circumcised; 4and thirty and three days she doth abide in the blood of her cleansing; against any holy thing she doth not come, and unto the sanctuary she doth not go in, till the fulness of the days of her cleansing. It total of 40 days.
This law applied to Mary after giving birth to Jesus, but ultimately it is for Zion giving birth to the resurrected Christ. She must wait a total of 40 days before entering the Temple. This is the new Temple which Christ is the chief cornerstone of, and the 40 days later falls on the Feast of Pentecost or the giving of the law which is for the new creation.
The result is found here:
Acts 2:1-4 (YLT)
1In the day of the Pentecost being fulfilled, they were all with one accord at the same place, 2there came suddenly out of the heaven a sound as of a bearing violent breath, and it filled all the house where they were sitting, 3and there appeared to them divided tongues, as it were of fire; it sat also upon each one of them, 4and they were all filled with the Holy Spirit, and began to speak with other tongues, according as the Spirit was giving them to declare.
These are Zion's children being born:
Revelation 12:17 (YLT)
and the dragon was angry against the woman, and went away to make war with the rest of her seed, those keeping the commands of God, and having the testimony of Jesus Christ.
Jerusalem, which is above, is the mother of us all. She is depicted as Zion here because she with the knowledge of our Father, is the Holy Spirit who brings judgement to the earth. To those who hear she would bring life eternal and to those who reject her everlasting destruction.
All of God's new creation are born from this woman and we all come from God's new heavens.
