2 Nephi 7:5

Chapters 7 and 8 of 2 Nephi reproduce material from Book of Isaiah (Isaiah 50–52:2), while an additional thirteen chapters (2 Nephi 12–24) quotes Isaiah 2–14—amounting to more than twenty-one total chapters of Isaiah within the Book of Mormon. Given that these records were reportedly engraved on small metal plates, a medium that would require significant effort and space (Jacob 4:1), this extensive duplication raises questions about purpose and necessity—especially since the Nephites already possessed Isaiah’s writings on the brass plates and the biblical text was independently preserved (as later evidenced by discoveries such as the Dead Sea Scrolls). Critics argue that this repetition, along with numerous phrases reflecting the King James Bible, suggests literary dependence rather than ancient origin. In contrast, Latter-day Saint scholars, including those from FAIR, contend that Isaiah was doctrinally central to Nephite theology. They emphasize that prophets like Nephi and Jacob not only quoted but interpreted Isaiah, indicating that these passages were intentionally preserved to teach covenant and messianic themes.
