“Two stones prepared by the Lord for interpreting languages (Mosiah 28:13–14) and the instrument through which Joseph Smith translated the Book of Mormon (Smith, [History of the] Church, 4:537). In Hebrew, the term ‘urim and thummim’ literally means ‘lights and perfections,’ referring to the stones’ ability to bring to light hidden things of the past (Alma 37:23). These stones, or ‘interpreters,’ as the Book of Mormon calls them (Mosiah 8:13; 28:20; Alma 37:21; Ether 4:5), were originally given to the brother of Jared, who was commanded to seal them up with his record as a means of translating the same (Ether 3:23–24)” (Largey, Book of Mormon Reference Companion, 773).
