Leviticus 13:19-21

New Revised Standard Version, Anglicised Catholic Edition

¹⁹ and in the place of the boil there appears a white swelling or a reddish-white spot, it shall be shown to the priest. 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 for seven days.
