Luke 1:30-35

The angel said to her, “Do not be afraid, Mary, for you have found favor with God. Listen carefully: you will conceive in your womb and give birth to a son, and you shall name Him Jesus. He will be great and eminent 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 (Israel) forever, and of His kingdom there shall be no end.” [Is 9:6, 7; Dan 2:44] Mary said to the angel, “How will this be, since I am a virgin and have no intimacy with any man?” Then the angel replied to her, “The Holy Spirit will come upon you, and the power of the Most High will overshadow you [like a cloud]; for that reason the holy (pure, sinless) Child shall be called the Son of God. [Ex 40:34; Is 7:14]
