A virgin did conceive.

I will not be the first person to tell you this, but the prophet Isaiah did not unequivocally predict the birth of a Messiah by parthenogenesis. St Matthew’s account of the annunciation to Joseph of the birth of a son to Mary, his betrothed, concludes that “All this took place to fulfill what had been spoken by the Lord through the prophet: ‘Look, the virgin shall conceive and bear a son…’” (Matthew 1:22-23), a citation of Isaiah 7:14. The wording in St Matthew’s Greek is identical to that of the Septuagint, the ancient Greek translation of the Old Testament.
