The Book of Leviticus
The Book of Leviticus is the third book of the Torah and of the Old Testament; scholars generally agree that it developed over a long period of time, reaching its present form during the Persian Period between 538–332 BC.
It consists of dialogue between God and Moses, which Moses repeats to the Israel. This takes place during Israel's' Exodus from Egypt.
It narrates how Moses leads the Israel in building the Tabernacle by God's instructions. Implements the Levitical system of giving, establishes the Priesthood duties to include how their priests are to present offerings in the Tabernacle and how to conduct themselves while camped around the holy tent sanctuary.
