Leviticus continues revelation concerning the second of three elements necessary for any nation to exist, namely, a people (Gen. 12:10--Exod. 19), their law (Exod. 20--Num. 10:10), and their land (Num. 10:11--Josh. 24).
Leviticus is essentially a narrative document that relates the events that transpired in the life of the Israelites while the nation camped at the base of Mt. Sinai. However most of the material in the book is legal in genre. The legal sections prepare the reader to understand the narrative sections not only in Leviticus but also in Numbers and the rest of the Bible. There are two clear narrative sections (chs. 8-10; 24:10-23). However the hinge chapter in the book, chapter 16, reads as narrative even though it is legislative material.

The first major section of Leviticus deals with how the Israelites were to conduct their public life as an expression of worship to God.
"The fact that the covenant between Yahweh and Israel was modeled after those of the ancient Near East in both form and function allows one to understand the myriad of cultic detail in the Pentateuch with unusual clarity. The sacrifices and offerings were designed to demonstrate the subservience of Israel, to atone for her offenses against her Sovereign, Yahweh, and to reflect the harmoniousness and peaceableness of the relationship thus established or reestablished."16
"Put differently, the main concern of Leviticus 1-16 is the continuance of the presence of God in the midst of the sinful nation, while Leviticus 17-27 records the effect of the presence of God upon the congregation. Consequently the abiding presence of God in the midst of the nation spans the entire contents of the Book of Leviticus."17
