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:
Cross-reference
Leviticus 14:45
Parallel
Leviticus 14:45 continues the same chapter: if scraping fails, the house must be demolished and taken to an unclean place—direct escalation of the process.
Leviticus 6:11
Parallel
In Leviticus 6:11, ashes are carried outside the camp to a clean place—a parallel disposal ritual, though destination differs (clean vs. unclean).
