Leviticus 13:19-21

International Standard Version

¹⁹ in place of the boil there remains a white swelling or a bright, white-reddish spot, he is to present himself to the priest. ²⁰ When the priest undertakes his examination and finds that it appears more extensive than skin deep and that its hair has turned white, then the priest is to declare him unclean, since an infectious skin disease has flourished in the boil. ²¹ If the priest undertakes an examination, but there’s no white hair in it and it’s not more extensive than skin deep, but it’s dull, then the priest is to isolate^[a] him for seven days.
