REVELATION 11:19; 12:1-6, 10

11 19Then God's temple in heaven was opened, and the ark of his covenant was seen within his temple; and there were flashes of lightning, voices, peals of thunder, an earthquake, and heavy hail. 12 1And a great portent appeared in heaven, a woman clothed with the sun, with the moon under her feet, and on her head a crown of twelve stars; 2she was with child and she cried out in her pangs of birth, in anguish for delivery. 3And another portent appeared in heaven; behold, a great red dragon, with seven heads and ten horns, and seven diadems upon his heads. 4His tail swept down a third of the stars of heaven, and cast them to the earth. And the dragon stood before the woman who was about to bear a child, that he might devour her child when she brought it forth; 5she brought forth a male child, one who is to rule all the nations with a rod of iron, but her child was caught up to God and to his throne, 6and the woman fled into the wilderness, where she has a place prepared by God, in which to be nourished for one thousand two hundred and sixty days. 10And I heard a loud voice in heaven, saying, "Now the salvation and the power and the kingdom of our God and the authority of his Christ have come, for the accuser of our brethren has been thrown down, who accuses them day and night before our God.

18And Uzziah said to her, "O daughter, you are blessed by the Most High God above all women on earth; and blessed be the Lord God, who created the heavens and the earth, who has guided you to strike the head of the leader of our enemies. 19Your hope will never depart from the hearts of men, as they remember the power of God.

Gospel
LUKE 1:26-38

26In the sixth month the angel Gabriel was sent from God to a city of Galilee named Nazareth, 27to a virgin betrothed to a man whose name was Joseph, of the house of David; and the virgin's name was Mary. 28And he came to her and said, "Hail, full of grace, the Lord is with you!" 29But she was greatly troubled at the saying, and considered in her mind what sort of greeting this might be. 30And the angel said to her, "Do not be afraid, Mary, for you have found favor with God. 31And behold, you will conceive in your womb and bear a son, and you shall call his name Jesus. 32He will be great, and will be called the Son of the Most High; and the Lord God will give to him the throne of his father David, 33and he will reign over the house of Jacob for ever; and of his kingdom there will be no end." 34And Mary said to the angel, "How shall this be, since I have no husband?" 35And the angel said to her, "The Holy Spirit will come upon you, and the power of the Most High will overshadow you; therefore the child to be born will be called holy, the Son of God. 36And behold, your kinswoman Elizabeth in her old age has also conceived a son; and this is the sixth month with her who was called barren. 37For with God nothing will be impossible." 38And Mary said, "Behold, I am the handmaid of the Lord; let it be to me according to your word." And the angel departed from her.
