Summary: Some claim that Jews or Israelites (like the Nephites) would not have used the language of their slave period — Egyptian — to write sacred records, that there is no evidence in Egyptology of something called "reformed Egyptian," and that the Book of Mormon's claim to have been written in this language is therefore suspect. However, the claim that Israelites would not use Egyptian is clearly false. By the ninth to sixth centuries before Christ, Israelites used Egyptian numerals mingled with Hebrew text. The Papyrus Amherst 63 contains a text of Psalms 20:2-6 written in Aramaic (the language of Jesus) using Egyptian characters. This text was originally dated to the second century B.C., but this has since been extended to the 4th century B.C.
Summary: It is claimed that Egyptian would be too lengthy and bulky on the plates to account for the Book of Mormon [Egyptian would take] "perhaps four times, or even more than four times, as much room as the English, and it is quite certain that, as the Book of Mormon is 600 pages thick, it would take at least a thousand plates to hold in the Egyptian language, what is there written."
