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 27

27:21 But the field, when it goeth out in the jubilee, shall be holy unto the LORD, as a field devoted; the possession thereof shall be the priest's.
