Chapter 9 is Jacob’s Commentary of Isaiah in 2 Nephi 7-8
“One of the most enlightening discourses ever delivered in regard to the atonement is found in the ninth chapter of 2 Nephi in the Book of Mormon. It is the counsel given by Jacob, brother of Nephi. It should be carefully read by every person seeking salvation. We have been taught that the greatest gift of God is eternal life, and eternal life comes through obedience to all of the commandments and covenants given to man by our Heavenly Father.” (Joseph Fielding Smith, Answers to Gospel Questions, 4:57)
