The Bible Dictionary states:
"Isaiah is the most quoted of all the prophets, being more frequently quoted by Jesus, Paul, Peter, and John (in his Revelation) than any other O.T. prophet. Likewise the Book of Mormon and the Doctrine and Covenants quote from Isaiah more than from any other prophet. The Lord told the Nephites that ’great are the words of Isaiah,’ and that all things Isaiah spoke of the house of Israel and of the gentiles would be fulfilled (3 Nephi 23:1-3).
“….The reader today has no greater written commentary and guide to understanding Isaiah than the Book of Mormon and the Doctrine and Covenants. As one understands these works better he will understand Isaiah better, and as one understands Isaiah better, he more fully comprehends the mission of the Savior, and the meaning of the covenant that was placed upon Abraham and his seed by which all the families of the earth would be blessed.”
