The Book of Mormon holds the writings of the Prophet Isaiah in highest regard and

cites many of his teachings from the Book of Isaiah that were contained on the brass plates

Nephi, who is one of the prophets in the Book of Mormon, copied chapters of Isaiah's words,

saying he did this so that readers might lift up their hearts and rejoice.

When the Savior himself visited the descendants of Lehigh, he cited chapters of Isaiah to them.

It's estimated that about one third of the entire Book of Isaiah is quoted in the text of the book

of Mormon. A challenge can arise, however, with what is known as Deuteron Isaiah.

Deuteron means second in Greek, and Deuteron Isaiah is the theory that there was a second author

or authors that wrote portions of the Book of Isaiah. Some scholars who subscribed to this theory

believe that portions of Isaiah were written after the Babylonian conquest of Jerusalem,

or in other words, after Lehigh and his family fled Jerusalem with the brass plates.

If Deuteron Isaiah is valid then, how did those writings make their way into the Book of Mormon?

This, of course, is not a new question. It has been explored for a hundred years, at least,

by Latter-day Saints scholars, with various answers to that query. Professor Joshua Sears of

the Department of Ancient Scripture has recently published an article that summarizes Latter-day

Saint responses and approaches to the questions of Deuteron Isaiah in the Book of Mormon.

So there's some ways in which there's such that creates attention. So again,

BH Roberts noted that, and he proposed some solutions to this, and other Latter-day

Saint scholars have done that for over a hundred years. So what I tried to do in this book chapter
