Leviticus 13:21-23

Holman Christian Standard Bible

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 must quarantine him seven days. ²² If it spreads further on the skin, the priest must pronounce him unclean; it is an infection. ²³ But if the spot remains where it is and does not spread, it is only the scar from the boil. The priest is to pronounce him clean.
