New Catholic Bible

³⁸ then the priest will go out of the door of the house, and he shall close up the house for seven days. ³⁹ On the seventh day the priest shall come back and see if the infection has spread on the walls of the house. ⁴⁰ The priest shall then command that they take the stones from the place that is infected and they shall throw them outside the city into an unclean place.
