And there appeared to him an angel of the Lord standing on the right side of the altar of incense. And Zechariah was troubled when he saw him, and fear fell upon him. But the angel said to him, “Do not be afraid, Zechariah, for your prayer is heard, and your wife Elizabeth will bear you a son, and you shall call his name John. And you will have joy and gladness, and many will rejoice at his birth; for he will be great before the Lord, and he shall drink no wine nor strong drink, and he will be filled with the Holy Spirit, even from his mother’s womb. And he will turn many of the sons of Israel to the Lord their God, and he will go before him in the spirit and power of Elijah, to turn the hearts of the fathers to the children, and the disobedient to the wisdom of the just, to make ready for the Lord a people prepared.” And Zechariah said to the angel, “How shall I know this? For I am an old man, and my wife is advanced in years.” And the angel answered him, “I am Gabriel, who stand in the presence of God; and I was sent to speak to you, and to bring you this good news. And behold, you will be silent and unable to speak until the day that these things come to pass, because you did not believe my words, which will be fulfilled in their time.” And the people were waiting for Zechariah, and they wondered at his delay in the temple. And when he came out, he could not speak to them, and they perceived that he had seen a vision in the temple; and he made signs to them and remained dumb. And when his time of service was ended, he went to his home.

Therefore the Lord himself will give you a sign. Look, the young woman is with child and shall bear a son, and shall name him Immanuel.
