And he shall go before him in the spirit and power of Elias, 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.

他必有以利亚的心志能力，行在主的前面，叫为父的心转向儿女，叫悖逆的人转从义人的智慧，又为主预备合用的百姓。」

这里说得很清楚，“有以利亚的心志能力” （in the spirit and power of Elias）的意思，是：行在主的前面，叫为父的心转向儿女，叫悖逆的人转从义人的智慧，又为主预备合用的百姓。

这很清楚说的是指施洗约翰有以利亚的能力和职分 （都是同一个圣灵所分赐），而不是说他们是同一个人。

施洗约翰的事工会和以利亚一样，都会大有能力，预备人心的悔改。

不但如此，施洗约翰是旧约先知最后的一位，而且也是最大的一位，因为其他人只能远远地预告，而施洗约翰则是直接引入了那预言中的弥赛亚。

Mat 11:13 - For all the prophets and the law prophesied until John. These words are to be considered in connection with Mat_11:11 and are a further proof of John's being greater than any of the prophets; because all the inspired writers and prophets, who were before him, prophesied of the Messiah as to come; and either spoke of him in obscure terms, or represented him under dark shadows and figures: whereas John spake of him as already come, and in plain terms, and directed to his very person; and since his time, there have been no prophecies concerning the Messiah and his kingdom; vision and prophecy are now sealed up; all which are acknowledged by the Jews themselves, who (b) say, כל הנביאים כולז לא נתנבאו אלא לימות המשיח, "all the prophets did not prophesy but to, or of the days of the Messiah". This was the subject, and these the limits of their prophecies; for they own (c), that

"from the day that the temple was destroyed, מן הנביאי בטילה נבואה, "prophecy was taken away from the prophets".''

Since that time, they confess they have had no prophet (d), and that they are not able to observe their signs.

玛拉基书4：5-6所指的以利亚，并不是指以利亚本人，而是指实际上是在遥指 （预表）着施洗约翰 （的职分，请参玛3：1，使者）。犹太人误解了玛拉基，因为是以利亚自己亲身会来 （所以，他们会问施洗约翰，你是不是以利亚）。

Mal 4:5 - Behold, I will send you Elijah the prophet,.... not Elijah in person, who lived in the times of Ahab; but John the Baptist, who was to come in the power and spirit of Elijah, Luk_1:17 between whom there was a great likeness in their temper and disposition; in their manner of clothing, and austere way of living; in their courage and integrity in reproving vice; and in their zeal and usefulness in the cause of God and true religion; and in their famous piety and holiness of life; and in being both prophets; see Mat_11:11 and that he is intended is clear from Mat_17:10. It is a notion of the Jews, as Kimchi and others, that the very Elijah, the same that lived in the days of Ahab, shall come in person before the coming of their Messiah they vainly expect, and often speak of difficult things to be left till Elijah comes and solves them; but for such a notion there is no foundation, either in this text or elsewhere. And as groundless is that of some of the ancient Christian fathers, and of the Papists, as Lyra and others, that Elijah with Enoch will come before the day of judgment, and restore the church of God ruined by antichrist, which they suppose is meant in the next clause.

Was John the Baptist really Elijah?
Matthew 11:13-14 and John 1:19-21
http://www.carm.org/diff/Matt11_13.htm

1. Yes, he was Elijah (Matthew 11:13-14) - "For all the prophets and the Law prophesied until John. 14"And if you care to accept it, he himself is Elijah, who was to come."
2. No, he was not Elijah (John 1:19-21) - "And this is the witness of John, when the Jews sent to him priests and Levites from Jerusalem to ask him, "Who are you?" 20And he confessed, and did not deny, and he confessed, "I am not the Christ." 21And they asked him, "What then? Are you Elijah?" And he *said, "I am not." "Are you the Prophet?" And he answered, "No."

The teaching of reincarnation is against the Old Testament. Therefore, Jesus was not teaching that John the Baptist was Elijah reincarnated. So, what did Jesus mean when He said that John the Baptist was Elijah? We see in Malachi 4:5 this prophecy, "Behold, I am going to send you Elijah the prophet before the coming of the great and terrible day of the Lord." Jesus is referring to the prophecy concerning Elijah. We see that the coming of Elijah was in the spirit of Elijah, which is so stated in Luke 1:13-17. The context is when Zecharias, John's father-to-be, was performing his priestly duties in the temple (Luke 1:8ff). An angel of the Lord appeared to Zacharias and said,

"Do not be afraid, Zacharias, for your petition has been heard, and your wife Elizabeth will bear you a son, and you will give him the name John. 14"And you will have joy and gladness, and many will rejoice at his birth. 15"For he will be great in the sight of the Lord, and he will drink no wine or liquor; and he will be filled with the Holy Spirit, while yet in his mother’s womb. 16"And he will turn back many of the sons of Israel to the Lord their God. 17"And it is he who will go as a forerunner before Him in the spirit and power of Elijah, to turn the hearts of the fathers back to the children, and the disobedient to the attitude of the righteous; so as to make ready a people prepared for the Lord," (Luke 1:13-17).

So, we see that John the Baptist was in the spirit of Elijah, but not actually Elijah reincarnated.
There is, however, a little more information that might prove interesting. Elijah wore, most probably, a camel's hair girdle. "And they answered him, "He was a hairy man with a leather girdle bound about his loins." And he said, "It is Elijah the Tishbite," (2 Kings 1:8). According to the Treasury of ????ure Knowledge, in reference to 2 Kings 1:8, Elijah . . .

"he wore a rough garment, either made of camels’ hair, as that of John Baptist, or of a skin, dressed with the hair on. Sir J. Chardin informs us, in a MS. note on this place, cited by Mr. Harmer, that the eastern dervishes and fakeers are clothed just as Elijah was, with a hairy garment, girded with a leathern girdle."

Concerning John the Baptist, it says in Matthew 3:4, "Now John himself had a garment of camel’s hair, and a leather belt about his waist; and his food was locusts and wild honey." It may be that Zecharias, who had access to the temple and things in the temple, may have acquired Elijah's camel hair garment and given it to John the Baptist to wear. This is speculation, but it is an interesting possibility.
