Tzaraath - Affliction of Clothing - Affliction of Housing

Affliction of Housing

The third and last type of tzaraath mentioned by the Torah affects buildings. If an individual notices an affliction on his house, he is to inform a kohen. The kohen will then command that they empty the house of all of its contents prior to his inspection; this is to prevent further financial loss, because should the house be confined, everything within it became impure as well.

When the kohen comes to perform the inspection, he looks for lesions on the wall that appear either intense green (ירקרקת) or intense red (אדמדמת) and that appear sunken below the plane of the wall's surface (שפל מן הקיר, literally "lower than the wall"). If this is what he sees, the kohen exits the house and confines it for seven days.

On the seventh day, upon re-evaluating the eruption, if the kohen sees that the eruption has spread beyond what it had been, the afflicted stones are removed, the area around the afflicted stones is scraped and both the removed stones and clay plaster are cast into a place of impurity. At least two afflicted stones are necessary for removal of any stones and at least two new stones must be used to fill the void. If the afflicted wall is shared by two houses owned by two neighbors, both neighbors must help to remove the afflicted stones, scrape and place the new stones, but only the owner of the house whose interior was afflicted performs the replastering. It is from this ruling that the proverb Oy l'rasha, oy l'scheino (או לרשע או לשכנו, "Woe to the wicked! Woe to his neighbor!") originates.

The void is filled with new stones and clay plaster and the house is confined for another seven days. If upon a second re-evaluation, the negah has returned after new stones have been plastered in, the negah is deemed tzaraath and the entire house must be dismantled. If the negah does not return, the house is pronounced pure, and the same purification process mentioned in relation to tzaraath of human flesh is employed here.

There are numerous limitations put on the tzaraath that afflicts houses:

• The house of a gentile is insusceptible to tzaraath.
• Only houses that possess four walls and four corners are susceptible. Similarly, only those houses that rest on the ground are susceptible, to the exclusion of those that are suspended above ground or are built on a boat.
• Tzaraath only affects houses that are built entirely out of stones, wood and clay plaster. If any of the four walls are built or internally overlaid with marble, natural outcropping of rock, brick or earthen soil, that wall is insusceptible to tzaraath, and a house cannot be rendered impure unless all four walls are susceptible.
• Two storey houses are treated as two distinct houses and the beams that serve as the floor of the upper storey and the roof of the lower storey are allowed to remain with whichever house remains.
• Houses are the only buildings that are susceptible to tzaraath (not, for example, barns or cattle stalls) and only houses that exist within the region of land originally divided among the 12 tribes, because the verse refers to beis eretz achuzaschem (בית ארץ אחזתכם, "a house of the land of your inheritance"); this also excludes houses in Jerusalem, because it was not given as an inheritance to any one tribe, but rather held jointly by all of Israel.
