Leviticus 13:20-22

English Standard Version Anglicised

²⁰ And the priest shall look, and if it appears deeper than the skin and its hair has turned white, then the priest shall pronounce him unclean. It is a case of leprous disease that has broken out in the boil. ²¹ But if the priest examines it and there is no white hair in it and it is not deeper than the skin, but has faded, then the priest shall shut him up for seven days. ²² And if it spreads in the skin, then the priest shall pronounce him unclean; it is a disease.
