1 Nephi 19:2

And I knew not at the time when I made them

that I should be commanded of the Lord to make these plates;

wherefore, the record of my father, and the genealogy of his fathers,

and the more part of all our proceedings in the wilderness

are engraven upon those first plates of which I have spoken;

wherefore, the things which transpired before I made these plates

are, of a truth, more particularly made mention upon the first plates.
