12And when Zacharias saw him, he was troubled, and fear fell upon him. 13But the angel said unto him, Fear not, Zacharias: for thy prayer is heard; and thy wife Elisabeth shall bear thee a son, and thou shalt call his name John. 14And thou shalt have joy and gladness; and many shall rejoice at his birth. 15For he shall be great in the sight of the Lord, and shall drink neither wine nor strong drink; and he shall be filled with the Holy Ghost, even from his mother's womb.16And many of the children of Israel shall he turn to the Lord their God. 17And he shall go before him in the spirit and power of Elias, to turn the hearts of the fathers to the children, and the disobedient to the wisdom of the just; to make ready a people prepared for the Lord. 18And Zacharias said unto the angel, Whereby shall I know this? for I am an old man, and my wife well stricken in years.
