Leviticus 14:38-40

International Standard Version

³⁸ The priest is to leave through the entrance to the house and seal the house for seven days. ³⁹ He is to return after seven days to examine it. If the contagion has spread to the walls of the house, ⁴⁰ then the priest is to command that they take out the contaminated stones and discard them in an unclean place outside the city.
