1 Nephi 1:17

But I shall make an account of my proceedings in my days—Behold I make an abridgment of the record of my father, upon plates which I have made with mine own hands; wherefore, after that I have abridged the record of my father, then will I make an account of mine own life.

But I will make an account of my life. I make a shorter version of my father’s record on plates I have made with my own hands. After I finish the shorter version of my father’s record, then I will make an account of my own life.

Instead, I'll tell my own story. I'm making a shorter version of my father's record on metal plates I made myself. After I finish summarizing his record, I'll write about my own life.
