=23.= Joseph began his work with the plates by patiently copying a number of characters, adding to some of the pages thus prepared the translations. The prophet's first assistant in the labor, Martin Harris, obtained permission to take away some of these transcripts, with the purpose of submitting them to the examination of men learned in ancient languages. He placed some of the sheets before Professor Charles Anthon, of Columbia College, who, after careful examination, certified that the characters were in general of the ancient Egyptian order, and that the accompanying translations appeared to be correct. Hearing how this ancient record came into Joseph's hands, Professor Anthon requested Mr. Harris to bring the original book for examination, stating that he would undertake the translation of the entire work; then, learning that a part of the book was sealed, he remarked, "I cannot read a sealed book"; and thus unwittingly did this man fulfill the prophecy of Isaiah concerning the coming forth of the volume:--"And the vision of all is become unto you as the words of a book that is sealed, which men deliver to one that is learned, saying, read this, I pray thee, and he saith, I cannot, for it is sealed."[782] Another linguist, a Dr. Mitchell, of New York, having examined the characters, gave concerning them a testimony in all important respects corresponding to that of Prof. Anthon. [782] Isaiah xxix, 11. =24. Arrangement of the Book of Mormon.=--The Book of Mormon comprises fifteen separate parts, commonly called books, distinguished by the names of their principal authors. Of these, the first six books, viz., I and II Nephi, Jacob, Enos, Jarom, and Omni, are literal translations from corresponding portions of the smaller plates of Nephi. The body of the volume, from the Book of Mosiah to Mormon, chapter vii, inclusive, is the translation of Mormon's abridgment of the larger plates of Nephi. Between the books of Omni and Mosiah "The Words of Mormon" occur, connecting the record of Nephi, as engraved on the smaller plates, with Mormon's abridgment of the larger plates for the periods following. The Words of Mormon may be regarded as a brief explanation of the preceding portions of the work, and a preface of the parts then to follow. The last part of the Book of Mormon, from the beginning of Mormon viii to the end of the volume, is in the language of Moroni, the son of Mormon, who first proceeds to finish the record of his father, and then adds an abridgment of a set of plates which contained an account of the Jaredites; this appears as the Book of Ether.[783] [783] See page 266.
