Leviticus can also be called “The Book of the Law of the Priests” as it contains very little historical matter, concerning itself with priestly legislation and the practice of the Law among the people. Much importance is placed upon Israel’s separation from all heathen influences so that the nation may retain its religious purity.

Leviticus 7

7:38 Which the LORD commanded Moses in mount Sinai, in the day that he commanded the children of Israel to offer their oblations unto the LORD, in the wilderness of Sinai.
