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

7:14 And of it he shall offer one out of the whole oblation for an heave offering unto the LORD, and it shall be the priest's that sprinkleth the blood of the peace offerings.
