New Catholic Bible

¹⁶and he will bring back many of the people of Israel to the Lord their God. ¹⁷With the spirit and power of Elijah he will go before him, to reconcile fathers with their children and to convert the disobedient to the ways of the righteous, so that a prepared people might be made ready for the Lord.”

¹⁸Zechariah said to the angel, “How can I be assured of this? For I am an old man and my wife is well past the stage of giving birth.”
