This agrees with the view that The Woman is Israel, thus refuting any views making Israel and The Church the same. I'm not a traditional dispensationalist, but there is a clear distinction.
This is proven by lots of old Prophetic references to Israel/Jerusalem being a woman (like Isaiah 62:4 where she is named Hephzibah), and often travailing in child birth, like Jeremiah 6 and Isaiah 66.
The Sun, Moon and Stars imagery comes from Genesis 37:9-10, one of Joseph's dreams.
"Behold, I have dreamed a dream more; and, behold, the sun and the moon and the eleven stars made obeisance to me." And he told it to his father, and to his brethren: and his father rebuked him, and said unto him, "What is this dream that thou hast dreamed? Shall I and thy mother and thy brethren indeed come to bow down ourselves to thee to the earth?"Which defines for us the Sun and Moon as Jacob and his Wife, and the eleven stars as Joseph's eleven brothers. Revelation 12 has twelve stars because now Joseph is included.
Commentators repeatedly claim the Sun is Jacob and the Moon is Rachel. The mother in mind here is clearly Leah not Rachel because Rachel had died by this point and so clearly never bowed before Joseph in Egypt when this was fulfilled. What confuses people is Jacob saying "your mother" to Joseph. But I don't doubt that by this point Leah was a mother to all 12 sons.
I argued in my Time of Jacob's Trouble post that Rachel in a sense serves typologically as a female personification of Israel. Through Benjamin and Joseph she was a mother to populations in both Kingdoms.
In Genesis 35:19 and 48:7 Rachel dies after giving birth to Benjamin and was buried in the same land that will become Bethlehem. (Some have argued those events only happened on the way to Bethlehem, either way they are thematically tied to Bethlehem by God's Word.) When the children of Bethlehem were slaughtered by Herod, Matthew 2:18 quotes Jeremiah 31:15.
Thus saith Yahuah; "A voice was heard in Ramah, lamentation, and bitter weeping; Rachel weeping for her children refused to be comforted for her children, because they were not."
So I think the reason the Woman herself is not in the dream in Genesis 37 is because the Woman in a sense is Rachel. Because it was a Tribe born to Leah that had Bethlehem when that slaughter happened, yet Rachel weeped for them as her own children.
