³⁸ the priest shall go out of the house, to the doorway, and ^[a]quarantine the house for seven days. ³⁹ The priest shall return on the seventh day and look; and if the mark has spread on the walls of the house, ⁴⁰ he shall order them to tear out the contaminated stones and throw them into an unclean place outside the city.
