The five books of Moses are referred to as the "Pentateuch." The Bible dictionary states:
"A Greek word meaning the fivefold book; a name given to the five books that stand at the beginning of our Bible, and that contain the Torah or law of Israel. The Pentateuch was written by Moses, although it is evident that he used several documentary sources from which he compiled the book of Genesis, beside a divine revelation to him. It is also evident that scribes and copyists have left their traces upon the Pentateuch as we have it today; for example, the explanation of Moses' supposed death (Deut. 34:5-12) was surely added by a later hand. But latter-day revelation confirms that Moses was the author of the first five books of the Bible."
The first five books of Moses represent the most important of all Jewish canon. The Torah is the Jewish bible and contains nothing more than the first five books of Moses. The Talmud contains many other Old Testament writings but these are considered to be less important – doctrinally and historically.
