Luke 1:17-19

American Standard Version

¹⁷ And he shall ^[a]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. ¹⁸ And Zacharias said unto the angel, Whereby shall I know this? for I am an old man, and my wife ^[b]well stricken in years. ¹⁹ And the angel answering said unto him, I am Gabriel, that stand in the presence of God; and I was sent to speak unto thee, and to bring thee these good tidings.
