Luke 1:17-19

New Matthew Bible

¹⁷ And he will go before him in the spirit and power of Elijah, to turn the hearts of the fathers to the children, and the unbelievers to the wisdom of the just men: to make the people ready for the Lord.

¹⁸ And Zacharias said to the angel, How may I be sure of this, seeing that I am old, and my wife well stricken in years?

¹⁹ And the angel answered and said to him, I am Gabriel who stands in the presence of God, and have been sent to speak to you and to show you these glad tidings.
