Leviticus 14:34-38

34“When you come to Canaan that I am going to give to you, mildew may appear in a house.

35The owner of that house must come and tell the priest that there is something that looks like mildew in his house.

36“Before the priest examines the house, he will order everything taken out of it so that nothing in the house will become unclean. Then the priest will go inside to examine the house.

37He will examine the mildew area on the walls. If it is green and red in sunken areas that are deeper than the rest of the wall,

38the priest will go out to the door of the house and close up the house for seven days.
