Leviticus 13:3-5

New International Version

³ The priest is to examine the sore on the skin, and if the hair in the sore has turned white and the sore appears to be more than skin deep, it is a defiling skin disease. When the priest examines that person, he shall pronounce them ceremonially unclean.^{(A) 4} If the shiny spot^(B) on the skin is white but does not appear to be more than skin deep and the hair in it has not turned white, the priest is to isolate the affected person for seven days.^{(C) 5} On the seventh day^(D) the priest is to examine them,^(E) and if he sees that the sore is unchanged and has not spread in the skin, he is to isolate them for another seven days.
