'Plaster' in the Bible

He is to have the inside of the house completely scraped, and the plaster that is scraped off must be dumped in an unclean place outside the city.

Then they must take different stones to replace the former ones and take additional plaster to replaster the house.

"But if the infection should return and it breaks out in the house after they have removed the stones and after scraping off [the plaster] of the house and after it has been replastered,

It must be torn down with its stones, its beams, and all its plaster, and taken outside the city to an unclean place.
