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 4

4:30 And the priest shall take of the blood thereof with his finger, and put it upon the horns of the altar of burnt offering, and shall pour out all the blood thereof at the bottom of the altar.
