As many people know, the Book of Mormon quotes heavily from Isaiah. In fact, according to the footnote for 2 Nephi 12:2a, 433 verses of Isaiah are quoted by Book of Mormon prophets. These frequently come in the form of full-length chapters being quoted at a time. Sometimes these verses are word-for-word identical with the King James Version of the Bible, but often the wording has been changed. A few of the verses of Isaiah are actually quoted multiple times, typically by different characters at different times in the Book of Mormon.
