Leviticus has the rituals for the various offerings that had to be made with clear rules on how to sacrifice the various animals, with various kinds of animal sacrificial offerings, a sin offering, a burnt offering, and a well-being offering.  Finally, there were the grain offerings.  The purpose of each one of these offerings was explained in detail.  Thus, the holocaust altar outside the tent or sanctuary received a lot of work.  Leviticus explained how priests were consecrated and ordained and exactly what they were to do.  There was an elaborate ordination service that lasted seven days.  Along with the ordination, the priestly functions of presenting the sin offerings, the burnt offerings, and the offerings of well-being were important.  With all the blood poured out at the holocaust altar, there was never any mention of a cleanup task.  The Levite priests had a strong cultic role in leading the worship of these Israelites.  In fact, there was the story of Aaron’s two sons dying, because they used the wrong incense.  Leviticus also contains the famous explanation of the difference between clean and unclean items.  The animals that chew the cud and have cleft hoofs were clean, while the others were not.  The creatures in the water with fins and scales were clean, otherwise they were not.  Certain birds were clean, while others were not.  There were even clean insects, those with jointed legs.  Sometimes the punishment for touching an unclean animal that made you unclean was that you had to wait until the evening when you had to wash yourself, not a very severe punishment.  There was also human uncleanness.  Women after childbirth were unclean for a certain number of days, depending on the sex of their child.  People with a variety of sores on their bodies went to the priest to be declared clean or unclean.  Many sores, boils, burns or growths on the body were considered leprous.  The priest, like a medical doctor, made the final decision on whether they would be considered a leper or not.  There was a strong use of quarantine.  There was a complex purification ritual to make oneself clean, but only after the disease had abated.  Finally, the law of holiness explained what makes them holy.  Yahweh is holy.  There was a code of holiness that was a further explanation of the commands to make the Israelites like Yahweh.  There were over forty of these ordinances or statutes that further expanded the meaning of the Ten Commandments.  There were guidelines and punishments for sexual misconduct.  Anything that touched Yahweh was holy, so that the priests were holy, especially the high priest.  Anything that touched the holy place became holy.  There were times of rest, the weekly Sabbath, the seven-year Sabbath and the Jubilee Year, every fifty years.  Yahweh would provide for them.  Obviously, this begins to happen when they arrived in the Promised Land.  The Jubilee Year was a little tricky, since they let all land go back to its original owner.  After all, Yahweh owned everything and they were just tenants or slaves on this earth.  A whole series of laws about transactions, for walled and un-walled property, with the role of the Levites came into play.  The consecrated vows were a little obscure.  Somehow, if you vowed to give something and decided that you wanted to take it back, you had to pay a 20% fee to get it back on top of the price of the item that you consecrated to Yahweh.  This appears to be another important role for the priest to decide.  He had to assess the value of these various animals and buildings.  Clearly the role of the priests dominates in this Book of Leviticus.  Do priests dominate in your life?
