(4) Did Joseph Smith hand over a marked-up Bible
to Oliver Cowdery when he came to the biblical quotations in the Book of
Mormon?
Oliver Cowdery’s
misspellings tell us that the answer is no. Joseph Smith dictated the biblical
quotations, just like all the rest of the Book of Mormon.
(5) When Joseph Smith produced his “New
Translation” of the Bible in 1830-33 (now known as the Joseph Smith
Translation), did he hand over a copy of the 1830 edition to the scribe to
correct the biblical text from?
In this case, we have
clear evidence that this is precisely what Joseph Smith was willing to do (unlike what he did when he dictated the
Book of Mormon text in 1828-29). There is at least one clear case of this
procedure, and perhaps others as well. (Royal Skousen, The History of the Text of the Book of Mormon, Part 5: The King James
Quotations in the Book of Mormon [Provo, Utah: The Foundation for Ancient
Research and Mormon Studies and Brigham Young University Press, 2019], 5,
