Leviticus 14:41

And he shall cause the house to be scraped within round about, and they shall pour out the dust that they scrape off without the city into an unclean place:
39

And the priest shall come again the seventh day, and shall look: and, behold, if the plague be spread in the walls of the house;

40

Then the priest shall command that they take away the stones in which the plague is, and they shall cast them into an unclean place without the city:

41

And he shall cause the house to be scraped within round about, and they shall pour out the dust that they scrape off without the city into an unclean place:

42

And they shall take other stones, and put them in the place of those stones; and he shall take other morter, and shall plaister the house.

43

And if the plague come again, and break out in the house, after that he hath taken away the stones, and after he hath scraped the house, and after it is plaistered;

Counter-Arguments

The strongest case that this verse does not belong in this theme.

Symbolic / Spiritual Interpretation

The verse describes a literal physical action of scraping and removing dust from a house, with no explicit or implied language suggesting a symbolic meaning for spiritual purity or moral holiness. The terms "unclean place" refer to a physical location outside the city for disposal, not a spiritual state.
