16. And he will convert many of the sons of Israel to the Lord their God.
17. 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."

20. And behold, you will be silent and unable to speak, until the day on which these things shall be, because you have not believed my words, which will be fulfilled in their time."
