According to McConkie and Millet, the "prophecies of the holy prophets" (1 Nephi 5:13) which were on the brass plates would have been similar to those contained in our Old Testament, but much more extensive and complete. The brass plates contained, for example, the prophecies of Abraham concerning the coming of Jesus Christ (Helaman 8:16-17), the prophecies of Jacob concerning the Nephite branch of his descendants (Alma 46:23-26), and prophecies of Joseph concerning Moses and Joseph Smith (2 Nephi 3). In addition we become aware, through references in the Book of Mormon relating to the brass plates, of such noble but little-known prophetic figures as Zenos, Zenock, and Neum. (1 Nephi 19:10-17; Jacob 5; Alma 33:3-17; 34:7; 3 Nephi 10:16.) [Joseph Fielding McConkie and Robert L. Millet, Doctrinal Commentary on the Book of Mormon, Vol. 1, p. 49]
