Leviticus
Leviticus, third book of the Hebrew Bible. Its name indicates its contents as a manual primarily concerned with priests, members of the priestly tribe of Levi, and their duties. Although Leviticus is basically a book of laws, it also contains some narrative text (chapters 8β9, 10:1β7, 10:16β20, and 24:10β14). The book is usually divided into five parts: sacrificial laws (chapters 1β7); the inauguration of the priesthood and laws governing their office (chapters 8β10); laws for ceremonial purity (chapters 11β16); laws governing the peopleβs holiness (chapters 17β26); and a supplement concerning offerings to the sanctuary and religious vows (chapter 27).
Scholars agree that Leviticus belongs to the Priestly (P) biblical source of the Pentateuchal traditions. This material is dated according to one theory to the 7th century bce and is regarded as the law upon which Ezra and Nehemiah based their reform. Older material, however, is preserved in the Priestly source, particularly the βHoliness Codeβ (chapters 17β26), dating from ancient times.
Because the closing chapters of the preceding book (Exodus) and the opening chapters of the following book (Numbers) are also derived from Priestly source materials, the existence of Leviticus as a separate book is presumably a secondary development. This hypothesis suggests that Leviticus properly belongs to a larger literary unit that is variously understood to include the first four, five, or six books of the Hebrew Bible.
