Verse 5. Behold I will send - Though the spirit of prophecy cease for four hundred years, yet at the expiring of those years, you shall have one sent, as great as Elijah. Elijah - Namely John the Baptist, who came in the spirit and power of Elijah, Luke i, 17, and therefore bears his name. Before - That is, immediately before; so he was born six months before Christ, and began his preaching a few years before Christ began to exercise his publick office. The great and dreadful day of the Lord - This literally refers to the times of vengeance upon the Jews, from the death of Christ to the final desolation of the city and temple, and by accommodation, to the end of the world.
Verse 6. And he - John the Baptist. Shall turn the heart - There were at this time many great and unnatural divisions among the Jews, in which fathers studied mischief to their own children. Of the children - Undutiful children estranged from their fathers. With a curse - Which ends in utter destruction; leaving Jerusalem a desolate heap, and a perpetual monument of God's displeasure. Some observe, that the last word of the Old Testament is a curse: whereas the New Testament ends with a blessing, yea, the choicest of blessings, The grace of our Lord Jesus Christ be with us all! Amen. Dec. 24, 1766.
