Infectious

“When someone has a swelling or rash or bright spot on his skin that may be an infectious skin disease, he must be brought to Aaron the priest or to one of his sons who is a priest.

…the priest shall examine the infection, and if it appears to be deeper than the skin and the hair in it is yellow and thin, the priest must pronounce him unclean; it is a scaly outbreak, an infectious disease of the head or chin.

But if there is a reddish-white sore on the bald head or forehead, it is an infectious disease breaking out on it.

This is the law for any infectious skin disease, for a scaly outbreak,

In cases of infectious skin diseases, be careful to diligently follow everything the Levitical priests instruct you. Be careful to do as I have commanded them.
