“If anyone has a sore, a rash, or an irritated area on his skin that turns into an infectious skin disease, he must be taken to the priest Aaron or to one of his sons who are also priests.
The priest will examine the disease. If the hair in the diseased area has turned white, and the diseased area looks deeper than the rest of his skin, it is an infectious skin disease. When the priest has examined him, he must declare him unclean.
“Command the Israelites to send outside the camp anyone who has a serious skin disease or a discharge or anyone who is unclean from touching a dead body.
