Bible revision

In June 1830, Smith dictated a revelation in which Moses narrates a vision in which he sees "worlds without number" and speaks with God about the purpose of creation and the relation of humankind to deity. This revelation initiated a revision of the Bible which Smith worked on sporadically until 1833 but which remained unpublished until after his death. He may have considered it complete, though according to Emma Smith, the biblical revision was still unfinished when Joseph died.

In the course of producing the Book of Mormon, Smith declared that the Bible was missing "the most plain and precious parts of the gospel". He produced a "new translation" of the Bible, not by directly translating from manuscripts in another language, but by amending and appending to a King James Bible in a process which he and Latter Day Saints believed was guided by inspiration; Smith asserted his translation would correct lacunae and restore what the contemporary Bible was missing. While many changes involved straightening out seeming contradictions or making small clarifications, other changes added large interpolations to the text. For example, Smith's revision nearly tripled the length of the first five chapters of Genesis into a text called the Book of Moses.
