In what ways will you improve because of Nephi’s words?
The superscription to the book of Jacob, which appears just under the title of the book, was part of the ancient record translated by the Prophet Joseph Smith and dictated by him to his scribe (see also, for example, 1 Nephi, Mosiah 9, and Alma 5).
Distinct from the superscription is the chapter summary, which is presented in italics between the chapter number and the beginning of the scriptural text. Chapter summaries, originally added in the 1920 edition of the Book of Mormon, give the reader an overview of what each chapter contains.
