Leviticus 13:28-40

²⁸However, if the spot is not changed and has not spread but has faded, it is only a scar from the burn, and the priest will declare that the person is permitted to be with other people again.

²⁹If a man or a woman has a sore on his head or on his chin,

³⁰the priest must examine it. If it appears to be deeper than just on the surface of the skin, and the hair in that spot has thinned out and has become yellowish, it is a contagious skin disease that causes itching. And the priest will declare that the person must stay away from other people.

³¹But when the priest examines that kind of sore, if it seems to be only on the surface of the skin and there is no healthy hair in it, the priest will tell the person to stay away from other people for seven days.

³²On the seventh day, the priest will examine the sore again. If it has not spread and if there is no yellow hair in that spot and if it appears to be only on the surface of the skin,

³³the person must shave the hair near the sore but not the hair on the sore. And the priest will tell him to stay away from other people for seven more days.

³⁴On the seventh day, the priest will examine that spot again. If it has not spread and it appears to be only on the surface of the skin, the priest will declare that the person is permitted to be with people again. The person must wash his clothes, and then he can be with other people.

³⁵But if the sore later spreads,

³⁶the priest must examine him again. If the itch/sore has spread, the priest does not need to look for yellow hair, because it is clear that the person has a contagious skin disease.

³⁷However, if the priest thinks that the spot has not changed, and healthy hair is growing in that area, it is clear that the itch has healed, and the priest will declare that the person is permitted to be with other people again.

³⁸When a man or a woman has white spots on the skin,

³⁹the priest should examine them. But if the spots are dull white, it is only a rash, and the priest will declare that the person is permitted to be with other people.

⁴⁰If a man loses the hair on any part of his head, he does not need to stay away from other people..
