Luke 1:32-36

He will be great and will be called the Son of the Most High; and the Lord God will give Him the throne of His father David;

and He will reign over the house of Jacob forever, and His kingdom will have no end.”

But Mary said to the angel, “How will this be, since I am a virgin?”

The angel answered and said to her, “The Holy Spirit will come upon you, and the power of the Most High will overshadow you; for that reason also the holy Child will be called the Son of God.

And behold, even your relative Elizabeth herself has conceived a son in her old age, and she who was called infertile is now in her sixth month.
