‏ Leviticus 14:42

Lev 14:37-42

If the leprous spot appeared in “greenish or reddish depressions, which looked deeper than the wall,” the priest was to shut up the house for seven days. If after that time he found that the mole had spread on the walls, he was to break out the stones upon which it appeared, and remove them to an unclean place outside the town, and to scrape the house all round inside, and throw the dust that was scraped off into an unclean place outside the town. He was then to put other stones in their place, and plaster the house with fresh mortar.
