“The prophecies of Malachi were given approximately 430 B.C., almost two centuries after Lehi left Jerusalem. These prophecies were considered so significant that the Father commanded that they be included in the Nephite scriptures. … Just as the Savior … quoted from Isaiah and Malachi, so did Moroni quote from them as he counseled Joseph Smith concerning the work of the Restoration (see Joseph Smith–History 1:36–40). This demonstrates the significance of these prophecies about the work of the last days in preparation for the Savior’s second coming” (McConkie et al., Doctrinal Commentary, 4:163).
