Matthew 17:11

Elias - shall first come, and restore all things - Or will reform, αποκαταστησει; this word our Lord quotes from the Septuagint; who render the Hebrew והשוב לב אבות על בנים vehesheb leb aboth al banim, he will cause the heart of the fathers to turn to the children, by, ος αποκαταστησει καρδιαν πατρος προς υιον, who will convert, or restore, the heart of the father to the son. We are not therefore to understand the version of the Septuagint quoted by our Lord in any other sense than the Hebrew will allow. No fanciful restoration of all men, devils and damned spirits, is spoken of as either being done, or begun, by the ministry of John; but merely that he should preach a doctrine tending to universal reformation of manners, and should be greatly successful: see Matthew 3:1-7, and especially Luke 3:3-15, where we find that a general reformation had taken place,

1. among the common people;

2. among the tax-gatherers; and

3. among the soldiers.

And as John announced the coming Christ, who was to baptize with the Holy Ghost, i.e. to enlighten, change, and purify the heart, that the reform might be complete, both outward and inward, he may be said, in the strictest sense of the word, to have fulfilled the prophecy: and that he was the Elijah mentioned by Malachi, the words of Gabriel to the virgin Mary prove; Luke 1:17. And he (John) shall go before him (Christ) 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, etc.; and that his ministry was powerfully effectual for this purpose, we have already seen.

Elias truly shall first come, and restore all things - He did not mean by this that Elijah was yet to come, for he tells them immediately Matthew 17:12 that he had come; but he meant to affirm that it was a true doctrine which the scribes taught, that Elijah would appear before the coming of the Messiah. To "restore" means to put into the former situation. See Matthew 12:13. Hence, it means to heal, to correct, to put in proper order. Here it means that Elijah would put things in a proper state; he would be the instrument of reforming the people, or of restoring them, in some measure, to proper notions about the Messiah and preparing them for his coming. Before the coming of John their views were erroneous, their expectations were worldly, and their conduct were exceedingly depraved. He corrected many of their notions about the Messiah (see Matthew 3), and he was the instrument of an extensive reformation, and thus restored them, in some degree, to correct views of their own system and of the Messiah, and to a preparation for his advent.

17:11 Regulate all things - In order to the coming of Christ.
