Nevertheless, I do not write anything upon plates save it be that I think it be sacred. And now, if I do err, even did they err of old; not that I would excuse myself because of other men, but because of the weakness which is in me, according to the flesh, I would excuse myself.  1 Nephi 19:6

Nephi, whose first book appears in the Book of Mormon, is one of the original writers from Israel who crossed the Sea to arrive at America.  He wrote the words of their travels on plates of ore (gold or brass).

At the end of 1 Nephi, he writes the above statement that seems to admit that "if I do err" leaving open the possibility of error.  He admits "weakness" and asks to be excused.

That's a scary admission to say that possibly this is book is all wrong.  Joseph Smith called the Book of Mormon the most correct book on earth.  Being the "most correct" leaves no room for error.

The Bible nor any of its writers ever say something written in its pages may be wrong or mistaken.

The Book of Mormon tries to pardon itself because it knew errors would be found.
