Luke 1:34-38

34Then Mary said to the angel, “How can this be, since I do not know a man?”

35And the angel answered and said to her, “The Holy Spirit will come upon you, and the power of the Highest will overshadow you; therefore, also, that Holy One who is to be born will be called the Son of God.

36Now indeed, Elizabeth your relative has also conceived a son in her old age; and this is now the sixth month for her who was called barren.

37For with God nothing will be impossible.”

38Then Mary said, “Behold the maidservant of the Lord! Let it be to me according to your word.” And the angel departed from her.
