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 3

3:6 And if his offering for a sacrifice of peace offering unto the LORD be of the flock; male or female, he shall offer it without blemish.
