1 Nephi 9:2

And now, as I have spoken concerning these plates,

behold they are not the plates

upon which I make a full account of the history of my people;

for the plates upon which I make a full account of my people

I have given the name of Nephi;

wherefore, they are called the plates of Nephi, after mine own name;

and these plates also are called the plates of Nephi.
