2 Nephi 11

Now I, Nephi, do speak somewhat concerning the words which I have written, which have been spoken by the mouth of Isaiah. For behold, Isaiah spake many things which were hard for many of my people to understand, for they know not concerning the manner of prophesying among the Jews; for I, Nephi, have not taught them many things concerning the manner of the Jews, for their works were works of darkness, and their doings were doings of abominations.
