Leviticus 14:36-38

New Century Version

³⁶ Then the priest must order the people to empty the house before he goes in to look at the mildew. This is so he will not have to say that everything in the house is unclean. After this, the priest will go in to look at it. ³⁷ He will look at the mildew, and if the mildew on the walls of the house is green or red and goes into the wall’s surface, ³⁸ he must go out and close up the house for seven days.
