Leviticus 13:36 In-Context

34 On the seventh day the priest must look at the sore. If it has not spread on the skin and it does not seem deeper than the skin, the priest must announce that the person is clean. So the person must wash his clothes and become clean.
35 But if the sore spreads on the skin after the person has become clean,
36 the priest must look at him again. If the sore has spread on the skin, the priest doesn't need to look for the yellowish hair; the person is unclean.
