In chapter 26, Nephi reviews some of the prophecies regarding the coming of Christ among the Nephites, the destruction of the wicked among the Nephites, and the coming forth of the Book of Mormon. The content of this chapter closely parallels the content of his vision of the history of the world contained in 1 Nephi 12-15. He also uses Isaiah 29 in this chapter, thereby explaining the relationship between Isaiah’s writings and his vision.
The first thing that is referenced is the appearance of the Savior to the Nephites. This is recorded in 1 Nephi 12:6, I saw the heaves open, and the Lamb of God descending out of heaven; and he came down and showed himself unto them. When Nephi says in verse 2, I have beheld…great wars and contentions among my people, he is referring to his vision where he saw the people of my seed gathered together in multitudes against the seed of my brethren; and they were gathered together to battle (1 Nephi 12:15). This pattern of referencing this vision will continue for most of the chapter. Eventually, Nephi begins to weave in the prophecies of Isaiah 29. By doing so, he helps us to understand the meaning of some of these Isaiah passages.
