Leviticus 13:20-22

New Revised Standard Version Catholic Edition

²⁰ The priest shall make an examination, and if it appears deeper than the skin and its hair has turned white, the priest shall pronounce him unclean; this is a leprous^[a] disease, broken out in the boil. ²¹ But if the priest examines it and the hair on it is not white, nor is it deeper than the skin but has abated, the priest shall confine him seven days. ²² If it spreads in the skin, the priest shall pronounce him unclean; it is diseased.
