A common "proof-text" Latter-day Saints often use to support the Book of Mormon is that of Isa 29. I have written about the problems of appealing to Isa 29 as biblical evidence for the coming forth of the Book of Mormon here. Interestingly, Daniel Ludlow, in his popular work on the Book of Mormon from 1978, wrote that Isa 29 is about the Old World and the New World; not that it is exhausted by the Nephites exclusively:
Isaiah 29:4. “And thou shalt be brought down, and shalt speak out of the ground.”—What at first looks like a prophecy about Jerusalem’s downfall is seen, in the light of Book of Mormon history, to include the remnant of Jerusalem’s children that settled in early America.
