Luke 1:29-35

But Mary was very startled by what the angel said and wondered what this greeting might mean. The angel said to her, “Don’t be afraid, Mary; God has shown you his grace. Listen! You will become pregnant and give birth to a son, and you will name him Jesus. He will be great and will be called the Son of the Most High. The Lord God will give him the throne of King David, his ancestor. He will rule over the people of Jacob forever, and his kingdom will never end.” Mary said to the angel, “How will this happen since I am a virgin?” The angel said to Mary, “The Holy Spirit will come upon you, and the power of the Most High will cover you. For this reason the baby will be holy and will be called the Son of God.
