This fifth volume published by the Book of Mormon Academy (often abbreviated BOMA) at Brigham Young University examines Jacob, the son of Lehi and the brother of Nephi. Although Jacob is sometimes eclipsed by the shadow of his brother Nephi, his writings represent a significant contribution to the doctrinal makeup of the Book of Mormon. The various authors of papers in this volume examine items such as Jacob’s development of demonology; the influence of Old Testament ideas and concepts on his teachings; his expressions of anxiety and deep feeling in his sermons; and much more.
