Leviticus 14:42-44

New International Version - UK

⁴² Then they are to take other stones to replace these and take new clay and plaster the house.

⁴³ ‘If the defiling mould reappears in the house after the stones have been torn out and the house scraped and plastered, ⁴⁴ the priest is to go and examine it and, if the mould has spread in the house, it is a persistent defiling mould; the house is unclean.
