The Book of Numbers is the fourth book of the Hebrew Bible, and the fourth of five books of the Jewish Torah. The book is the sacred history of the Israelites as they wandered in the wilderness following the departure from Sinai and before their occupation of Canaan, the Promised Land. It describes their sufferings and their numerous complaints against God.
Third book of the OT containing instructions for priests and worship. The Hebrew name of Leviticus comes from the first word in the book, wayyiqraʾ, “and he called.” In the later rabbinic works and similarly in the Syuriac translation, the Peshitta, the book was called torat hohanim, “book of the priests.” The English title comes from the Latin Vulgate translation of the Greek term Leuitikon. This is an adjectival form, “Levitical,” which thus means “that which concerns the priests.”
The Book of Exodus is the second book of the Bible. It tells a story about Israelites being delivered from slavery, involving an Exodus from Egypt through the hand of Jehovah, the leadership of Moses, revelations at the biblical Mount Sinai, and a subsequent "divine dwelling" of God with Israel.
