Isaiah 7:10-14 (ESV)
The Sign of Immanuel
Again the Lord spoke to Ahaz: “Ask a sign of the Lord your[a] God; let it be deep as Sheol or high as heaven.” But Ahaz said, “I will not ask, and I will not put the Lord to the test.” And he said, “Hear then, O house of David! Is it too little for you to weary men, that you weary my God also? Therefore the Lord himself will give you a sign. Behold, the virgin shall conceive and bear a son, and shall call his name Immanuel.
Hebrews 10:4-10 (ESV)
“Sacrifices and offerings you have not desired,
but a body have you prepared for me;
in burnt offerings and sin offerings
you have taken no pleasure.
Then I said, ‘Behold, I have come to do your will, O God,
as it is written of me in the scroll of the book.’”
When he said above, “You have neither desired nor taken pleasure in sacrifices and offerings and burnt offerings and sin offerings” (these are offered according to the law), then he added, “Behold, I have come to do your will.” He does away with the first in order to establish the second. And by that will we have been sanctified through the offering of the body of Jesus Christ once for all.
Luke 1:26-38 (ESV)
Birth of Jesus Foretold
In the sixth month the angel Gabriel was sent from God to a city of Galilee named Nazareth, to a virgin betrothed to a man whose name was Joseph, of the house of David. And the virgin’s name was Mary. And he came to her and said, “Greetings, O favored one, the Lord is with you!” But she was greatly troubled at the saying, and tried to discern what sort of greeting this might be. And the angel said to her, “Do not be afraid, Mary, for you have found favor with God. And behold, you will conceive in your womb and bear a son, and you shall call his name Jesus. He 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, and he will reign over the house of Jacob forever, and of his kingdom there will be no end.”
And Mary said to the angel, “How will this be, since I am a virgin?”
And the angel answered 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. And behold, your relative Elizabeth in her old age has also conceived a son, and this is the sixth month with her who was called barren. For nothing will be impossible with God.” And Mary said, “Behold, I am the servant of the Lord; let it be to me according to your word.” And the angel departed from her.
