Leviticus 13:29-33 ▼

29 |Now when a man or a woman has a skin rash on the head or the man develops a skin rash under his beard,

30 if when the priest examines the skin rash and indeed it appears more extensive than skin deep, and it's accompanied by fine, yellowish hair, then the priest is to declare him unclean. The scales on the head or the beard are an infectious skin disease.

31 But when the priest examines the scales of the skin rash and it doesn't appear more extensive than skin deep and there's no black hair in it, then the priest is to isolate him for seven days.

32 When the priest examines the skin rash on the seventh day and finds that indeed the scab did not spread, there's no yellowish hair on it, and the scales don't appear more extensive than skin deep,

33 then he is to be shaven, but the scab is not to be shaved off. The priest is to isolate him a second time for seven days.
