15 For he will be great in the eyes of the Lord; he will not take wine or strong drink; and he will be full of the Spirit of God from his birth.

16 And through him great numbers of the children of Israel will be turned to the Lord their God.

17 And he will go before his face in the spirit and power of Elijah, turning the hearts of fathers to their children, and wrongdoers to the way of righteousness; to make ready a people whose hearts have been turned to the Lord.
