Leviticus: This book gets its name from the tribe of Levi. The Levites were set aside by God to be priests for the entire nation of Israel. They were to receive no inheritance of land but their portion was to be the Lord. Their primary call was to be ministers and priests to the Lord.
Although the book of Leviticus contains critical information for the performance of priestly duties, its scope is much broader and gives vital information on how to live “holy before the Lord.” The Book of Leviticus was written during and shortly after the time of Moses by an unknown author or authors.
A vital lesson from Leviticus is that God expects his people to live lives separate and different from the world around them. In the Old Testament this difference focuses on externals: the people of God wear different clothing, eat different food, and serve their God in a different way from the peoples and religions around them.
