garment must be immersed in a mikveh (מקוה, "ritual bath") and is then pure. Fabrics and clothing affected by tzaraath were required by the text to be burnt entirely, unless it was the form of tzaraath that faded after washing but came back after being torn out, in which case it could be considered ritually pure as soon as the tzaraath had gone, and it had subsequently been washed. 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 (אוי לרשע אוי 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,
