Leviticus 13:26

But if the priest should look, and, behold, there is not in the bright spot any white hair, and it should not be lower than the skin, and it should be dark, then the priest shall separate him seven days.

But if the priest look on it, and, behold, there be no white hair in the bright spot, and it be no lower than the other skin, but be somewhat dark; then the priest shall shut him up seven days:

But if the priest examines it, and behold, there is no white hair in the bright spot, and it isn’t deeper than the skin, but has faded, then the priest shall isolate him seven days.
