Negaim 12:7
The kohein comes at the end of the week and inspects the nega again. If it has returned, “he shall break down the house, its stones, its timber and all the mortar of the house. He shall carry them out of the city to an unclean place” (Leviticus 14:45). Spreading that adjoins the original spot is significant regardless of its size; distant spreading must be no smaller than the size of a split bean. A nega that returns to a house must be no smaller than the size of two split beans.
Negaim 13:1
There are ten cases of negaim in houses: If a nega fades or disappears in the first week, it may be scraped and it is then clean. If a nega fades or disappears in the second week, it may be scraped and the owner must bring the bird offering. If a nega spread in the first week, the stones must be removed, the wall scraped and plastered, and another week given. If the nega returns, the whole house must be demolished. If the nega doesn’t return, the bird offering must be brought. If the nega didn’t change in the first week but it spread in the second, the stones must be removed, the wall scraped and plastered, and another week must be given. If the nega returns, the house must be demolished; if it doesn’t return, the bird offering must be brought. If the nega didn’t change for both weeks, the stones must be removed, the wall scraped and plastered, and a week must be given. If the nega returns the house must be demolished; if it doesn’t return, the bird offering must be brought. If a new nega appeared before purity could be achieved through the bird offering, the house must be demolished; if it appeared after purity was achieved through the bird offering, the nega must be inspected as if it had appeared for the first time.
