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 8

8:17 But the bullock, and his hide, his flesh, and his dung, he burnt with fire without the camp; as the LORD commanded Moses.
