Leviticus 15-16

Ok this chapter is gross because it talks about bodily discharges, so I will try to keep it short. If someone has a discharge, then he's unclean and anything he touches will be unclean, like his bed or chair. If someone comes into contact with him, they'll have to wash their clothes and bathes and that person will be unclean until the evening. When he no longer has the discharge, he'll have to wait 7 days for the ceremonial cleansing. Then he can do the cleansing by bringing two birds to the priest and using them for a sin and burnt offering. A woman is unclean during her period and the same rules apply as in the bodily discharge. It says in Leviticus that they Israelites have to be separate so they won't die in their uncleaniness.

Leviticus 16 establishes the Day of Atonement, better known as Yom Kippur. It is one of the most holiest days and you atone for the sins you've made against God over the past year.

God says that Aaron can no longer come into the Most Holy Place whenever he wants to because he'll die. When Aaron enters the sanctuary, he needs "to offer a bull for his own sin offering to make atonement for himself and his household." He also has to bring two male goats for a sin offering and ram for a burnt offering. One of the goats is for the Lord and the other is for the scapegoat. The one for the Lord is sacrificed for a sin offering while the scapegoat is used for making atonement by sending it into the desert as a scapegoat. "In this way, he will make atonement for the Most Holy Place because of the uncleanness and rebellion of the Israelites, whatever their sins have been." Then he has to do make atonement for the Tent of Meeting and the altar. "He is to lay both hands on the head of the liver goat and confess over it all the wickedness and rebellion of the Israelites - all their sins - and put them on the goat's head." Then he sends the goat away into the desert. Then Aaron is to wash his clothes and bathe become going back to camp. Also on this day every year from now on, God instructed them to take a sabbath of rest that day, and the Lord would cleanse them from all their sins!
