Leviticus 13:6-8

6On the seventh day, the priest must look at the person. The mark may not be so dark and it may not be any bigger. The priest can say that the disease has left that person. The person must wash his clothes.

7A person might see that the mark on his skin had grown. This might happen after the priest had said that the disease had left him. Then the person must go again to the priest.

8The priest must look at the person. The mark might be bigger. The priest must say that the person has a disease. It is a disease that he could give to other people.
