Leviticus 13:20-22

Amplified Bible, Classic Edition

²⁰ And if when the priest examines it it looks lower than the skin and the hair on it is turned white, the priest shall pronounce him unclean; it is the disease of leprosy; it has broken out in the boil.

²¹ But if the priest examines it and finds no white hair in it and it is not lower than the skin but appears darker, then the priest shall bind it up for seven days.

²² If it spreads in the skin, [he] shall pronounce him unclean; it is diseased.
