Leviticus 13:20-22

The Voice

²⁰ The priest will check; and if the affected area appears to go deep beneath the skin and the hairs on it have turned white, then the priest will pronounce the person unclean. It is a case of serious skin disease that started out as a boil. ²¹ But if the priest examines the person and finds there are no white hairs on it and the condition does not appear to go deep beneath the skin, and is, in fact, improving, then the priest will quarantine the infected person for seven days. ²² If the condition spreads to new places on the skin, the priest will pronounce him unclean; it is a serious infection.
