Nephi's introduction is typical of Egyptian writings.
Hugh Nibley
"The first three verses of 1 Nephi, sharply set off from the rest of the text, are a typical colophon, a literary device that is highly characteristic of Egyptian compositions. Typical is the famous Bremer-Rhind Papyrus, which opens with a colophon containing (1) the date, (2) the titles of Nasim, the author, (3) the names of his parents and a word in praise of their virtues, with special mention of his father's prophetic calling, (4) a curse against anyone who might 'take the book away,' probably 'due to fear lest a sacred book should get into impure hands.' Compare this with Nephi's colophon: (1) his name, (2) the merits of his parents, with special attention to the learning of his father, (3) a solemn avowal (corresponding to Nasim's curse) that the record is true, and the assertion, 'I make it with mine own hand' (1 Nephi 1:3)--an indispensable condition of every true colophon, since the purpose of a colophon is to establish the identity of the actual writer-down (not merely the ultimate author) of the text. Egyptian literary writings regularly close with the formula iw-f-pw 'thus it is,' 'and so it is.' Nephi ends the main sections of his book with the phrase, 'And thus it is, Amen' (1 Nephi 9:6; 14:30; 22:31)." (Lehi in the Desert/The World of the Jaredites, p. 15.)
