The Pentateuch contains the first five books of the Hebrew Bible: Genesis, Exodus, Leviticus, Numbers, and Deuteronomy are all authored by Moses. The Pentateuch’s literary category follows the traditional Jewish classification of these texts as the Torah.
The five Books of the Law are as follows: Genesis, which means “beginning,” since it describes the beginning of God’s creation. Exodus, which means “escape from slavery in Egypt.” Leviticus, a book explaining how the tribe of Levi ordained worship; Deuteronomy, which means “second law,” since it contains a complete list of the extra laws revealed by God through Moses.
David is credited with 73 Psalms, Asaph with 12, the Sons of Korah with 11, Solomon with 2, Moses, Ethan, and Heman with one each, and the remaining 50 are unknown.
