In Moroni’s vision of the future, he is given to understand that the language of the Nephites as represented on the plates is not known. Certainly he is not referring to his own day, as there are many who know that language. Moroni is referring to the plates, and the fact that they will not be translated by human means. This will not be a job for the scholars, but for one who is able to use the “means for the interpretation thereof” that have been prepared by the Lord.
