²⁹ Whenever a man or woman has an infection, whether on the head or in the beard, ³⁰ the priest will examine it. If it appears to be deeper than the skin, and there is thin yellow hair in it, the priest will declare the person unclean; it is a case of scabies—a skin disease of the head or beard. ³¹ When the priest examines the scabies infection, if it does not appear to be deeper than the skin, but there is no black hair in it, the priest will quarantine the person with the scabies infection for seven days.
