Malachi 1:1

1 The burden of the aword of the Lord to Israel by Malachi.

3 Nephi 24:1

1 And it came to pass that he commanded them that they should write the words which the Father had given unto Malachi, which he should tell unto them. And it came to pass that after they were written he expounded them. And these are the words which he did tell unto them, saying: Thus said the Father unto Malachi—Behold, I will asend my bmessenger, and he shall prepare the way before me, and the Lord whom ye seek shall suddenly ccome to his temple, even the dmessenger of the covenant, whom ye delight in; behold, he shall come, saith the Lord of Hosts.

Doctrine and Covenants 110:14

14 Behold, the time has fully come, which was spoken of by the mouth of Malachi—testifying that he [Elijah] should be sent, before the great and dreadful day of the Lord come—

Doctrine and Covenants 128:17

17 And again, in connection with this quotation I will give you a quotation from one of the prophets, who had his eye fixed on the arestoration of the priesthood, the glories to be revealed in the last days, and in an especial manner this most glorious of all subjects belonging to the everlasting gospel, namely, the baptism for the dead; for Malachi says, last chapter, verses 5th and 6th: Behold, I will send you bElijah the prophet before the coming of the great and dreadful day of the Lord: And he shall turn the heart of the fathers to the children, and the heart of the children to their fathers, lest I come and smite the earth with a curse.

Doctrine and Covenants 138:46

46 And aMalachi, the prophet who testified of the coming of bElijah—of whom also Moroni spake to the Prophet Joseph Smith, declaring that he should come before the ushering in of the great and dreadful cday of the Lord—were also there.

Doctrine and Covenants 133:64

64 And also that which was written by the prophet aMalachi: For, behold, the bday cometh that shall cburn as an oven, and all the proud, yea, and all that do dwickedly, shall be stubble; and the day that cometh shall burn them up, saith the Lord of hosts, that it shall leave them neither root nor branch.

Joseph Smith—History 1:36

36 After telling me these things, he commenced quoting the prophecies of the Old Testament. He first quoted part of the athird chapter of Malachi; and he quoted also the fourth or last chapter of the same prophecy, though with a little variation from the way it reads in our Bibles. Instead of quoting the first verse as it reads in our books, he quoted it thus:
