The phrase “hiss forth” only occurs twice in all of the modern scriptural canon; here and in 2 Nephi 29:2. In both cases, the context is the coming forth of the Book of Mormon. Moroni gives a specific introduction here that adds the confirmation that Moroni sees the Book of Mormon as a fulfillment of prophecy of a voice coming from the dust, even through the probable reference is Nephi rather than Isaiah.
