And there appeared to him an angel of the Lord standing on the right side of the altar of incense. And Zechari′ah was troubled when he saw him, and fear fell upon him. But the angel said to him, “Do not be afraid, Zechari′ah, 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 Eli′jah,
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 Zechari′ah 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.”
– Luke 1:11-20, 57-64
