Be careful during an outbreak of leprosy to follow precisely all that the Levitical priests instruct you; as I have commanded them, so you should do.

The priest must then examine the infection on the skin of the body, and if the hair in the infection has turned white and the infection appears to be deeper than the skin of the body, then it is a diseased infection, so when the priest examines it he must pronounce the person unclean.
