A:No: there was no seventh book of Moses. The first five books of the Bible are traditionally ascribed to Moses, although biblical scholars say that atribution is not really true. There are other writings ascribed to Moses, including the "Sixth and Seventh Books of Moses", which purport to explain the magic whereby Moses won the biblical magic contest with the Egyptian priest-magicians, parted the Red Sea and performed other miraculous feats. Moses wrote no book that has come down to us today, and certainly no sixth or seventh book. No such book was ever considered for inclusion in the Bible.
