Alma 37:2

and I also command you that ye shall keep a record of this people, according as I have done, upon the plates of Nephi, and keep all these things sacred which I have kept, even as I have kept them: for it is for a wise purpose that they are kept;

I also tell you to keep a record of this people, just like I have done. Write on the plates of Nephi. Keep all these things safe, just like I have kept them. They are kept for a good reason.

I’m also telling you to keep a record of our people, just as I’ve done, on the plates of Nephi. Keep all these things sacred, just as I have kept them. There’s a wise purpose behind it all.
