Leviticus 1:1-2

1 FOR behold, it came to pass that *fifty and five years had passed away from the time that Lehi left Jerusalem; wherefore, Nephi gave me, Jacob, a commandment concerning the small plates, upon which these things are engraven.

2 And he gave me, Jacob, a commandment that I should write upon these plates a few of the things which I considered to be most precious; that I should not touch, save it were lightly, concerning the history of this people which are called the people of Nephi.
