Editing Second Nephi (section)

==== Deutero-Isaiah ====
In more modern times, scholars have theorized based on variation in style and structure that more than one author wrote the book of Isaiah. These authors are referred to as [[Isaiah]], Deutero-Isaiah, and Trito-Isaiah. Deutero-Isaiah is thought to be born after the time Lehi’s family would have left Jerusalem.{{sfn|Washburn|1954|p=190}} Many of those writings which are considered to be part of Deutero-Isaiah are cited in Second Nephi as quotations from Isaiah. This implies that the Book of Mormon narrative disagrees that this section of Isaiah was written by someone other than its namesake.{{sfn|Gorton|1994|pp=49–51}} An LDS doctrine course teacher's supplement cites the Book of Mormon as evidence that Isaiah wrote the whole book of Isaiah since pieces from throughout the book are said to be from the already compiled brass plates which Lehi's sons took from Jerusalem around 600 BC.{{sfn|Smith|1983|p=49}}
