It is talking about the Virgin of Israel, Miriam, who is the elect of Israel, the very Israel of God. You cannot separate her from her son, God with us, nor from her nation, Israel, nor from the holy catholic apostolic church. If you go to heaven, you'll get used to her.
Miriam nor virgin appear in the verse...And the woman travailed at birth...Could not possibly be Mary the mother of Jesus...How could your religion even consider such a thing???
