Luke 1:34-37
34 Mary said to the angel, "But how? I've never slept with a man."
35 The angel answered, The Holy Spirit will come upon you, the power of the Highest hover over you;
Therefore, the child you bring to birth will be called Holy, Son of God.
36 "And did you know that your cousin Elizabeth conceived a son, old as she is? Everyone called her barren, and here she is six months' pregnant! 37 Nothing, you see, is impossible with God."
