Luke 1:35

32 He shall be great, and shall be called the Son of the Most High: and the Lord God shall give unto him the throne of his father David:

33 and he shall reign over the house of Jacob for ever; and of his kingdom there shall be no end.

34 And Mary said unto the angel, How shall this be, seeing I know not a man?

35 And the angel answered and said unto her, The Holy Spirit shall come upon thee, and the power of the Most High shall overshadow thee: wherefore also the holy thing which is begotten shall be called the Son of God.

36 And behold, Elisabeth thy kinswoman, she also hath conceived a son in her old age; and this is the sixth month with her that was called barren.

37 For no word from God shall be void of power.

38 And Mary said, Behold, the handmaid of the Lord; be it unto me according to thy word. And the angel departed from her.
