He will go before him in the spirit and power of Elijah, 'to turn the hearts of the fathers to the children,' and the disobedient to the wisdom of the just; to make ready a people prepared for the Lord."
To turn the hearts of the fathers to their children. By a very expressive figure of speech, Abraham, Isaac, and Jacob, and the rest of the patriarchs, are represented here as having their hearts alienated from the Jews, their children, because of their unbelief and disobedience; but that the Baptist should so far succeed in converting them to the Lord their God, that these holy men should again look upon them with delight, and acknowledge them for their children. Some think that by the children, the Gentiles are meant, and by the fathers, the Jews.
