Leviticus 14:38-40

Holman Christian Standard Bible

³⁸ the priest is to go outside the house to its doorway and quarantine the house for seven days. ³⁹ The priest is to return on the seventh day and examine it. If the contamination has spread on the walls of the house, ⁴⁰ the priest must order that the stones with the contamination be pulled out and thrown into an unclean place outside the city.
