Pentateuch and Abbreviations of the Books of the Bible

The Pentateuch, which consists of the first five books of the Bible (Genesis, Exodus, Leviticus, Numbers, Deuteronomy), enjoys particular prestige among the Jews as the "Law," or "Torah," the concrete expression of God's will in their regard. It is more than a body of legal doctrine, even though such material occupies many chapters, for it contains the story of the formation of the People of God: Abraham and the Patriarchs, Moses and the oppressed Hebrews in Egypt, the birth of Israel in the Sinai covenant, the journey to the threshold of the Promised Land, and the "discourses" of Moses.
