Luke 1:37

34 And Mary said to the angel, How may this be, because I have had no knowledge of a man?

35 And the angel in answer said to her, The Holy Spirit will come on you, and the power of the Most High will come to rest on you, and so that which will come to birth will be named holy, Son of God.

36 Even now Elisabeth, who is of your family, is to be a mother, though she is old: and this is the sixth month with her who was without children.

37 For there is nothing which God is not able to do.

38 And Mary said: I am the servant of the Lord; may it be to me as you say. And the angel went away.

39 Then Mary got up and went quickly into the high lands, to a town of Judah;

40 And went into the house of Zacharias and took Elisabeth in her arms.
