Moses (Hebrew: מֹשֶׁה, Modern Moshe Tiberian Mōšeh; Greek: Mωϋσῆς in both the Septuagint and the New Testament; Arabic: ' موسىٰ, Mūsa) was, according to the Hebrew Bible, a religious leader, lawgiver, and prophet, to whom the authorship of the Torah is traditionally attributed. Also called Moshe Rabbenu in Hebrew (Hebrew: מֹשֶׁה רַבֵּנוּ, Lit. "Moses our Teacher/Rabbi"), he is the most important prophet in Judaism, and is also considered an important prophet by Christianity, Islam, the Bahá'í Faith, Rastafari, and many other faiths. Moses has also been an important symbol in American history, from the first settlers up until the present.
...He therefore assembled the tribes, and delivered to them a parting address, which forms the Book of Deuteronomy. In this address it is commonly accepted that he recapitulated the Law, reminding them of its most important features.

Nothing. Almost nothing.
http://en.wikipedia.org/wiki/Dead_Sea_scrolls
The Dead Sea Scrolls are a collection of about 900 documents, including texts from the Hebrew Bible, discovered between 1947 and 1956 in eleven caves in and around the ruins of the ancient settlement of Khirbet Qumran on the northwest shore of the Dead Sea in the present day West Bank.
The texts are of great religious and historical significance, as they include the oldest known surviving copies of Biblical and extra-biblical documents and preserve evidence of great diversity in late Second Temple Judaism. They are written in Hebrew, Aramaic and Greek, mostly on parchment, but with some written on papyrus. These manuscripts generally date between 150 BCE to 70 CE.
It is now becoming increasingly clear that the Old Testament scripture was extremely fluid until its canonization around A.D. 100.
About 35% of the DSS biblical manuscripts belong to the Masoretic tradition, 5% to the Septuagint family, and 5% to the Samaritan, with the remainder unaligned. The non-aligned fall into two categories, those inconsistent in agreeing with other known types, and those that diverge significantly from all other known readings. The DSS thus form a significant witness to the mutability of biblical texts at this period.
