“Book of Mormon peoples apparently engaged in commerce on a substantial scale. By 130 B.C., after dissident Nephites who lived in the land of Nephi taught literacy to the Lamanites in the area, the latter ‘began to increase in riches, and began to trade one with another and wax great, and began to be a cunning and a wise people’ (Mosiah 24:7). A century later considerable intermixture of the two basic populations, Nephites and Lamanites, temporarily occurred, and ‘they did have free intercourse one with another to buy and to sell, and to get gain.’ As a result, ‘they became exceeding rich, both the Lamanites and the Nephites’ (Helaman 6:7–9)” (Sorenson, Mormon’s Codex, 273–74).
