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 19

19:32 Thou shalt rise up before the hoary head, and honour the face of the old man, and fear thy God: I am the LORD.
