1 Nephi 19:1

And it came to pass that the Lord commanded me, wherefore I did make plates of ore, that I might engraven upon them the record of my people. And upon the plates which I made, I did engraven the record of my father, and also our journeyings in the wilderness, and the prophecies of my father; and also, many of mine own prophecies have I engraven upon them.

The Lord commanded me to make metal plates. I carved our family’s history on them. I wrote about my father and our travels in the wilderness. I also wrote down my father’s prophecies and many of my own prophecies.

I, Nephi, did what the Lord commanded—I made metal plates to record my people’s story. On these plates I wrote about my father, our journey through the wilderness, and my father’s prophecies. I added many of my own prophecies too.
