To make sense of how the Lord would bring about His promises made to Japheth and his seed, a messianic figure must be brought into the equation, namely Joseph who was sold into Egypt. Joseph of Old serves as an important archetype. For members of the Church of Jesus Christ of Latter-day Saints his preeminence comes to the fore in certain passages in the Book of Mormon cited by Lehi revealing important prophecies Joseph of Old had given. Joseph foretold of two great seers arising from his loins during the last days. One of them was none other than Joseph Smith Jr. of whom Brigham Young taught descended through one of the sons of Joseph, claiming the prophet was a pure Ephraimite.
