Mosiah priority
Mosiah priority is a theory about the creation of the Book of Mormon arguing that the original manuscript began not with 1 Nephi (found at the beginning of the Book of Mormon), but midway through, starting with Mosiah. According to Mosiah priority, after the text of Mosiah through the end of the Book of Mormon was dictated, Joseph Smith returned to the beginning and dictated 1 Nephi through Words of Mormon.
