Pentateuch means the first five books of the Bible. These books are Genesis, Exodus, Leviticus, Numbers, and Deuteronomy. The word Pentateuch comes from two Greek words that mean "five books" or "five scrolls".
The Pentateuch tells the story from the Creation of the world to the death of Moses and the preparation of the Israelites to enter the land of Canaan. The story is told in three parts. The first part (Genesis 1-11) is about the Creation and the beginning of human beings on earth. The second part (Genesis 12-50) are the stories of the ancestors of the Israelites, mainly Abraham, Isaac, Jacob, and Joseph. The third part, beginning with the book of Exodus, describes how the Israelites left Egypt and the early history of the people of Israel as a nation. It also has many laws about how the Israelites must build their society. Deuteronomy is mostly Moses's final speech to his people and a summary of the Pentateuch.
The Pentateuch is the oldest part of the Bible, but scholars do not know exactly when these books were written[source?]. The earliest parts may have been written more than 1,000 years before the final parts[source?]. Modern archaeological discoveries suggest that some of the oldest stories in Genesis may date back three thousand years.[source?]
