Much of the double portion of Tazria-Metzora deals with the laws governing tzara’at, an enigmatic affliction which takes the form of a skin disease in people, but which can also afflict clothing and houses. Due to its symptoms of skin discoloration and the requirement that the victim be quarantined, tzara’at has often been mistakenly identified as leprosy. However, it is not caused by infection or a biological imbalance; rather, it is the physical but supernatural manifestation of an individual’s spiritual malaise.
