Luke 1:13-17

But the Angel said to him: "Do not be afraid, Zechariah, for your prayer has been heard, and your wife Elizabeth shall bear a son to you. And you shall call his name John. And there will be joy and exultation for you, and many will rejoice in his nativity. For he will be great in the sight of the Lord, and he will not drink wine or strong drink, and he will be filled with the Holy Spirit, even from his mother's womb. And he will convert many of the sons of Israel to the Lord their God. And he will go before him with the spirit and power of Elijah, so that he may turn the hearts of the fathers to the sons, and the incredulous to the prudence of the just, so as to prepare for the Lord a completed people."
