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 24

24:3 Without the veil of the testimony, in the tabernacle of the congregation, shall Aaron order it from the evening unto the morning before the LORD continually: it shall be a statute for ever in your generations.
