The Book of Mormon and Isaiah

The Book of Mormon prophet Nephi loved Isaiah and quoted extensively
from him. (The Book of Mormon contains 414 verses from Isaiah, about
32% of the book of Isaiah. Isaiah began prophesying about 740 BC and
Nephi lived about 600 BC.) Here are some quotes from Nephi about the
value of Isaiah. Note that he not only felt Isaiah's writings would
be valuable to his own people, but also to us in the last days.
Isaiah testifies and prophesies of Christ as our redeemer. That is
why it is of such great worth.

"And I did read many things unto them which were written in the
books of Moses; but that I might more fully persuade them to believe
in the Lord their Redeemer I did read unto them that which was written
by the prophet Isaiah; for I did liken all scriptures unto us, that it
might be for our profit and learning." (1 Nephi 19:23)

"And now I, Nephi, write more of the words of Isaiah, for my soul
delighteth in his words. For I will liken his words unto my people,
and I will send them forth unto all my children, for he verily saw my
Redeemer, even as I have seen him." (2 Nephi 11:2)

"Wherefore, they are of worth unto the children of men, and he that
supposeth that they are not, unto them will I speak particularly, and
confine the words unto mine own people; for I know that they shall be
of great worth unto them in the last days; for in that day shall they
understand them; wherefore, for their good have I written them." (2
Nephi 25:8)
