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 2

2:12 As for the oblation of the firstfruits, ye shall offer them unto the LORD: but they shall not be burnt on the altar for a sweet savour.
