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 25

25:50 And he shall reckon with him that bought him from the year that he was sold to him unto the year of jubilee: and the price of his sale shall be according unto the number of years, according to the time of an hired servant shall it be with him.
