Leviticus 14:37-39

New Catholic Bible

³⁷ He shall look at the infection, and if the infection on the walls of the house is a green or red spot, and if it seems to be deeper than the surface, 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.
