Luke 1:11-18

And there appeared unto him an angel of the Lord standing on the right side of the altar of incense. And Zacharias was troubled when he saw him, and fear fell upon him. But the angel said unto him, Fear not, Zacharias: because thy supplication is heard, and thy wife Elisabeth shall bear thee a son, and thou shalt call his name John. And thou shalt have joy and gladness; and many shall rejoice at his birth. For he shall be great in the sight of the Lord, and he shall drink no wine nor strong drink; and he shall be filled with the Holy Spirit, even from his mother’s womb. And many of the children of Israel shall he turn unto the Lord their God. And he shall go before his face in the spirit and power of Elijah, to turn the hearts of the fathers to the children, and the disobedient to walk in the wisdom of the just; to make ready for the Lord a people prepared for him. And Zacharias said unto the angel, Whereby shall I know this? for I am an old man, and my wife well stricken in years.
