Nephi wrote his record about 30 years after Lehi’s family left Jerusalem and journeyed to the promised land (see 1 Nephi 19:1–5; 2 Nephi 5:28–31). The record begins with an abridgment of his father’s record, comprising 1 Nephi 1–8. Mormon’s abridgment of Lehi’s record was in the lost 116 manuscript pages. It was a translation from a portion of the plates called the “Book of Lehi” (see D&C 10, section introduction; 10:42, footnote a; commentary for 1 Nephi 19:1–6 on page 42).
