Metzora
The Torah describes the procedure for a metzora (a person afflicted with tzara'at) upon the conclusion of his isolation period. This process extends for a week and involves korbanot and immersions in a mikveh. Then, a kohen must pronounce the metzora pure. A metzora of limited financial means may substitute lesser offerings for the more expensive animals. Before a kohen diagnoses that a house has tzara'at, household possessions are removed to prevent them from also being declared ritually impure. The tzara'at is removed by smashing and rebuilding that section of the house. If the tzara’at signs reappear, the entire building must be razed. The Torah details which bodily secretions render a person spiritually impure, and thereby prevent his contact with holy items. And the Torah defines how one regains a state of ritual purity.
Acharei Mot
Hashem instructs the kohanim to exercise extreme care when they enter the Mishkan. On Yom Kippur, the Kohen Gadol (High Priest) is to approach the holiest part of the Mishkan after special preparations and wearing special clothing. He brings offerings unique to Yom Kippur, including two identical goats that are designated by lottery. One is "for Hashem, and is offered in the Temple, while the other is "for Azazel," to be in the desert. The Torah states the individual's obligations on Yom Kippur: On the 10th day of the seventh month, one must “afflict” oneself. We are to abstain from eating and drinking, anointing, wearing leather footwear, washing and marital relations.
Consumption of blood is prohibited. The blood of slaughtered birds and undomesticated beasts must be covered. The people are warned against engaging in the wicked practices that were common in Egypt. Incest is defined and prohibited. Marital relations are forbidden during a woman's monthly cycle. Homosexuality, bestiality and child sacrifice are prohibited.
