Leviticus 13:20-22

Christian Standard Bible

²⁰ The priest will make an examination, and if the spot seems to be beneath the skin and the hair in it has turned white, the priest must pronounce him unclean; it is a case of serious skin disease that has broken out in the boil. ²¹ But when the priest examines it, if there is no white hair in it, and it is not beneath the skin but is faded, the priest will quarantine him seven days. ²² If it spreads further on the skin, the priest must pronounce him unclean; it is in fact a disease.
