Luke 1:16-20

16He will bring back many of the people of Israel to the Lord their God.

17And he will go on before the Lord, in the spirit and power of Elijah, to turn the hearts of the parents to their children and the disobedient to the wisdom of the righteous—to make ready a people prepared for the Lord.”

18Zechariah asked the angel, “How can I be sure of this? I am an old man and my wife is well along in years.” 19The angel said to him, “I am Gabriel. I stand in the presence of God, and I have been sent to speak to you and to tell you this good news.

20And now you will be silent and not able to speak until the day this happens, because you did not believe my words, which will come true at their appointed time.”
