Tazria

The Torah commands a woman to bring a korban after the birth of a child. A son is to be circumcised on the eighth day of his life. The Torah introduces the phenomenon of tzara'at (often mistranslated as leprosy) — a miraculous affliction that attacks people, clothing and buildings to awaken a person to spiritual failures. A kohen must be consulted to determine whether a particular mark is tzara'at or not. The kohen isolates the sufferer for a week. If the malady remains unchanged, confinement continues for a second week, after which the kohen decides the person's status. The Torah describes the different forms of tzara'at. One whose tzara'at is confirmed wears torn clothing, does not cut his hair, and must alert others that he is ritually impure. He may not have normal contact with people. The phenomenon of tzara'at on clothing is described in detail.

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 the 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.
