Leviticus 13:21-23

Revised Standard Version Catholic Edition

²¹ But if the priest examines it, and the hair on it is not white and it is not deeper than the skin, but is dim, then the priest shall shut him up seven days; ²² and if it spreads in the skin, then the priest shall pronounce him unclean; it is diseased. ²³ But if the spot remains in one place and does not spread, it is the scar of the boil; and the priest shall pronounce him clean.
