Tazria - 2 April 2011 - 27 Adar 2 5771
It was the Septuagint, the early Greek translation of the Hebrew Bible, that translated tzaraat, the condition whose identification and cleansing occupies much of Tazria and Metsora as lepra, giving rise to a long tradition identifying it with leprosy.
That tradition is now widely acknowledged to be incorrect. First, the condition described in the Torah simply does not fit the symptoms of leprosy. Second, the Torah applies it not only to various skin conditions but also to mildew on clothes and the walls of houses, which certainly rules out any known disease. The Rambam puts it best: “Tsaraat is a comprehensive term covering a number of dissimilar conditions. Thus whiteness in a person's skin is called tsaraat. The falling off of some of his hair on the head or the chin is called tsaraat. A change of colour in garments or in houses is called tsaraat.” (Hilkhot Tumat Tsaraat 16: 10)
Seeking to identify the nature of the phenomenon, the sages sought for clues elsewhere in the Torah and found them readily available. Miriam was smitten by tsaraat for speaking badly about her brother Moses (Num. 12: 10). The Torah later gives special emphasis to this event, seeing in it a warning for all generations: “Be careful with regard to the plague of tsaraat . . . Remember what the Lord your God did to Miriam along the way after you came out of Egypt” (Deut. 24: 8-9).
It was, in other words, no normal phenomenon but a specific divine punishment for lashon hara, evil speech. The rabbis drew attention to the verbal similarity between metsora, a person afflicted by the condition, and motzi shem ra, someone guilty of slander.
Rambam, on the basis of rabbinic traditions, gives a brilliant account of why tsaraat afflicted both inanimate objects like walls and clothes, and human beings:
It [tsaraat] was a sign and wonder among the Israelites to warn them against slanderous speaking. For if a man uttered slander, the walls of his house would suffer a change. If he repented, the house would again become clean. But if he continued in his wickedness until the house was torn down, leather objects in his house on which he sat or lay would suffer a change. If he repented they would again become clean. But if he continued in his wickedness until they were burned, the garments which he wore would suffer a change. If he repented they would again become clean. But if he continued in his wickedness until they were burned, his skin would suffer a change and he would become infected by tsaraat and be set apart and alone until he no more engaged in the conversation of the wicked which is scoffing and slander. (Hilkhot Tumat Tsaraat 16: 10)
'Unclean! Unclean!' he must call out . . . Since he is unclean, he must remain alone, and his place shall be outside the camp. (Lev. 13: 45-46)
Said the rabbis: Because his words separated husband from wife and brother from brother, his punishment is that he is separated from human contact and made an outcast from society (Arakhin 16b).
