Is 7:14
Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive, and bear a son, and shall call his name Immanuel.
matt 1:20
But while he thought on these things, behold, the angel of the Lord appeared unto him in a dream, saying, Joseph, thou son of David, fear not to take unto thee Mary thy wife: for that which is conceived in her is of the Holy Ghost.
21 And she shall bring forth a son, and thou shalt call his name Jesus: for he shall save his people from their sins.
22 Now all this was done, that it might be fulfilled which was spoken of the Lord by the prophet, saying,
23 Behold, a virgin shall be with child, and shall bring forth a son, and they shall call his name Emmanuel, which being interpreted is, God with us.

...Conceived of the Holy Ghost and born of the Virgin Mary...
Saint Augustine:
