A Mysterious Affliction

Vayikra 13-14 speaks at length about the various forms of tzara'at, the impurity caused thereby, and the process by which the afflicted can be purified.  Despite the many details, however, the malady remains very much in the realm of the unknown: 

• Nature of the condition – What is tzara'at?  Why does a person get afflicted?  Is it a natural disease that anyone can contract, or a supernatural and punitive phenomenon sent by the Divine?
• Forms of Tzara'at – How do tzara'at of the house, clothing and body relate to each other?  Do they all stem from the same condition, or is one name given to a variety of distinct afflictions? Can the discoloration of clothing and homes have a natural explanation, or is this evidence that the plague as a whole must be miraculous?
• Impurity – Finally, what about the condition makes it defile?  What does it share with other conditions which cause impurity such as contact with the dead, bodily discharges or child bearing?

Biblical Cases

Throughout Tanakh there are several episodes which speak of someone who is afflicted by tzara'at. 

• Shemot 4 – When Moshe complains at the Burning Bush that the nation won't believe that Hashem had appeared to him, Hashem gives him a sign in the form of his hand being struck with tzara'at.
• Bemidbar 12 – After Miriam speaks against Moshe, Hashem punishes her with tzara'at.
• Shemuel II 3 – After Yoav kills Avner without David's approval, David curses him that he should be plagued with tzara'at.
• Melakhim II 5 – Naaman, the Aramean general, is cured from his tzara'at by bathing seven times in the Jordan, as commanded by Elisha. 
• Melakhim II 5 – Elisha curses Gechazi for speaking in his name against his wishes.
• Melakhim II 7 – Four metzoarim sitting outside the city, are the first to discover that the enemy has fled, leaving behind enough food to save the Israelites from the famine caused by the siege.
• Divrei HaYamim II 26 – After overstepping his bounds in bringing an incense offering King Uziyahu is struck with tzara'at.

What do all these various cases have to teach about the nature of the malady and why someone is afflicted by it?

Diagnosis and Treatment of the Defiled Person

Much of Vayikra 13 is devoted to a discussion of how to determine if the afflicted person is in fact impure, and how he should be treated once he is so labelled. In addition to the many difficulties involved in understanding the technical details, several other aspects of the process beg questioning as well:

• Role of the priest – The priest is assigned the task of determining the status of the plagued individual, house or clothing. Is this role a purely spiritual one, related to issues of purity, or did the priest play some medical role as well, actually diagnosing the malady?
• Seven day intervals – In several instances, there are seven day waiting periods in between inspections of the plague and how it has spread or healed.  What is the purpose of these intervals? Are they set to determine the progression of the disease or is there some spiritual component to the process as well?
• Who is impure – Is there any logic to the symptoms that designate the impure state?  For instance, why would a person who is totally covered in tzara'at, and entirely white, be rendered pure while smaller spots might declare him impure?
• "בְּגָדָיו יִהְיוּ פְרֻמִים וְרֹאשׁוֹ יִהְיֶה פָרוּעַ וְעַל שָׂפָם יַעְטֶה"– What is the purpose of these actions? the torn coat and loose hair are classically signs of mourning, but why should such mourning be mandated?  Moreover, why should the upper lip be covered?
• Isolation – Why is the impure individual expelled from the camp and forced into isolation?  Though all forms of impurity require a distancing form the Mikdash, this is the only state which requires leaving the Israelite camp.
