Just to add to the confusion, there is the birth of a child. This is what the WTBTS has to say about it in their Revelation book
Subject: The heavenly woman gives birth, Michael battles with Satan and casts him to earth
Time of fulfillment: From the enthronement of Christ Jesus in 1914 up to the great tribulation
2 John now sees a great sign—one of outstanding interest for God’s people. It introduces a thrilling prophetic vision, the meaning of which was first published in the March 1, 1925, issue of The Watch Tower in an article entitled “Birth of the Nation” and then again in 1926 in the book Deliverance. This brilliant flash of Bible understanding became a historic marker in the advancement of Jehovah’s work. So let John describe the drama as it starts to unfold: “And a great sign was seen in heaven, a woman arrayed with the sun, and the moon was beneath her feet, and on her head was a crown of twelve stars, and she was pregnant. And she cries out in her pains and in her agony to give birth.”—Revelation 12:1, 2.
3 For the first time, John beholds a woman in heaven. She is, of course, not a literal woman. Rather, she is a sign, or a symbol. (Revelation 1:1) What does she symbolize? In the inspired prophecies, women at times represent organizations “married” to outstanding personalities. In the Hebrew Scriptures, Israel was spoken of as a wife of Jehovah God. (Jeremiah 3:14) In the Greek Scriptures, the congregation of anointed Christians is spoken of as Christ’s bride. (Revelation 21:9-14) The woman John here sees is also married to someone, and she is about to give birth. Who is her husband? Well, later her child is “caught away to God and to his throne.” (Revelation 12:5) Jehovah thus claims the child as his own. Therefore, the woman that John sees must be Jehovah’s symbolic wife.
4 About eight centuries earlier, Jehovah had addressed this symbolic wife, saying: “All your sons will be persons taught by Jehovah.” (Isaiah 54:5, 13) Jesus quoted this prophecy and showed that these sons were his faithful followers, who later formed the congregation of anointed Christians. (John 6:44, 45) So members of this congregation, spoken of as God’s sons, are also children of God’s symbolic wife. (Romans 8:14) The apostle Paul adds the final piece of information when he says: “The Jerusalem above is free, and she is our mother.” (Galatians 4:26) The “woman” seen by John, then, is “the Jerusalem above.”
5 Exactly what, though, is Jerusalem above? Since Paul spoke of her as “above,” and John sees her in heaven, she is clearly not an earthly city; neither is she the same as “New Jerusalem,” since that organization is the bride of Christ, not Jehovah’s wife. (Revelation 21:2) Notice that she is crowned with 12 stars. The number 12 is associated with completeness in an organizational setting. Hence, these 12 stars seem to indicate that she is an organizational arrangement in heaven, just as ancient Jerusalem was on earth. Jerusalem above is Jehovah’s universal organization of spirit creatures that acts as his wife, both in serving him and in producing offspring.....
A Son, a Male
.... Rather, it is the birth of God’s Kingdom in 1914 as a reality, with Jesus—now in heaven for close to 20 centuries—enthroned as King.—Revelation 12:10.
God's Son - the newborn Messianic Kingdom with Jesus as King and the 144,000 ruling as King's and Priest's
Because Jesus' bride is the 144,000 then Jesus is marrying his brother.
...show respect for Jehovah’s organization, for she is our mother and the beloved wife of our heavenly Father, Jehovah God.
