Leviticus 21 is about the rules for priests..... "A priest must not make himself ceremonially unclean". God says, "I am the Lord, who makes them holy."

Leviticus 20 describes the punishments for many "detestable" sins and God says again, "consecrate yourselves and be holy, because I am the Lord your God. Keep My decrees and follow them. I am the Lord, who makes you holy....and I have set you apart from the nations to be My own."

In Leviticus 19, the Lord says to the Israelites, " Be holy because I, the Lord your God, am holy." Then a bunch of laws and commandments are mentioned again... respect your parents, don't make idols, follow all the sacrifice regulations, don't steal or lie, love your neighbor as yourself, and others. After each set of commands, God says "I am the Lord". Then the Lord gives a few reminders of "due punishment" if sins are committed. The chapter concludes , "Keep all my decrees and all my laws and follow them. I am the Lord." You know that you better pay attention when God follows with "I am the Lord". It's like God is saying, "Hey! It's Me talking and you better listen. This is really important and there will be consequences if you don't obey." He says this phrase at least 15 times in this chapter alone. Maybe He's serious. I wonder if that might work with my kids? "Behave yourself. I am the Daddy." That might actually work if my kids saw that I always behaved perfectly. God says "Be holy because I am holy".

In Leviticus 18, God tells Moses to instruct the Israelites not to do the wicked things that the Egyptians and the Canaanites practice, but rather obey God's decrees and laws. The Lord said, " Keep my decrees, for the man who obeys them will live by them. I am the Lord." God asks them not to defile themselves like those whom He is going to drive out of Canaan. "Everyone who does any of these detestable things--such persons must be cut off from their people... I am the Lord your God."

Leviticus 17 describes more rules for the Israelites to obey regarding sacrifices and offerings made before the "Tent of Meeting". "Any Israelite or any alien living among you who hunts any animal or bird that may be eaten must drain out the blood and cover it with earth, because the life of every creature is its blood. That is why I have said to the Israelites, You must not eat the blood of any creature, because the life of every creature is its blood; anyone who eats it must be cut off."

Leviticus 16
"When Aaron has finished making atonement for the Most Holy Place, the Tent of Meeting and the altar, he shall bring forward the live goat. He is to lay both hands on the head of the live goat and confess over it all the wickedness and rebellion of the Israelites—all their sins—and put them on the goat's head. He shall send the goat away into the desert in the care of a man appointed for the task. The goat will carry on itself all their sins to a solitary place; and the man shall release it in the desert."

Leviticus 11-15 explains details of many guidelines given to the Israelites to live a holy lifestyle in obedience to their Lord, maintaing "cleanness". These included rules about unclean foods, purification after childbirth, regulations about skin infections, mildew contamination, and unclean bodily discharges. The Lord directed, "You must keep the Israelites separate from things that make them unclean, so they will not die in the uncleanness for defiling my dwelling place, which is among them". In these chapters, the word "unclean" occurs more than a hundred times, and each time refers to restrictions in conduct for the Israelites in order to remain acceptable for worshiping their holy God.
