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 23

23:20 And the priest shall wave them with the bread of the firstfruits for a wave offering before the LORD with the two lambs: they shall be holy to the LORD for the priest.
