1 Nephi 19:6

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.

Nevertheless, I do not write anything upon plates
