Luke 1:16-18

King James Version

¹⁶ And many of the children of Israel shall he turn to the Lord their God.

¹⁷ And 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.

¹⁸ And Zacharias said unto the angel, Whereby shall I know this? for I am an old man, and my wife well stricken in years.
