Leviticus 13:31-39
31 But if the priest examines the netek-lesion, and, regardless of whether its appearance is deeper or not deeper than that of the skin, there are not two black hairs—or hairs of any other color, including gold—in it, the priest must quarantine the person with the netek-lesion for seven days.
32 The priest must examine the lesion on the seventh day. If the netek has shrunk to less than the symptomatic area or naturally colored hair has appeared within it, the person is no longer defiled; the priest must pronounce him rid of this defilement, and he must undergo the purification process that will be detailed later.
If the netek has spread and there is no naturally colored hair in its new growth, or if two or more gold hairs have appeared within it, the individual is defiled and the priest must pronounce him so.
But if there is no change—i.e., the netek has not spread and no naturally colored or gold hair appeared in it—then, regardless of whether the appearance of the netek is deeper or not deeper than that of the skin, the person must shave himself in the vicinity of the netek, but he must not shave the netek or two rows of hairs surrounding and adjacent to the netek, in order to enable the priest to easily determine if it has spread when he next examines it. The priest must then quarantine the person with the netek again for seven days.
The seventh day of the first quarantine week also counts as the first day of the second quarantine week.
34 The priest must examine the netek on the seventh (i.e., 13th) day. If the netek has spread, or if gold hair has appeared within it, the individual is defiled and the priest must pronounce him so. If there is again no change—i.e., the netek did not spread on the skin and no gold hair appeared on it—then, regardless of whether its appearance is deeper or not deeper than that of the skin, the priest must pronounce him rid of this defilement, and the individual must immerse himself and his garments in a mikveh and undergo the rest of the purification process that will be described later, and then he will become rid of this defilement in fact. No third quarantine period is needed.
35 But if the netek spreads on the skin after he has been declared rid of this defilement, 36 the priest must examine him, and if the netek has indeed spread on the skin, the priest need not search for a gold hair, for he is defiled on account of the netek having spread. Similarly, if two gold hairs appear on the skin after he has been declared rid of this defilement, this suffices to defile him.
37 But if the appearance—i.e., color—of the netek has remained the same, or if black hair or hair of any color other than gold has grown in it, the netek has healed. He is therefore not defiled, and the priest must pronounce him rid of this defilement.
Suspicion of Tzara’at due to a Lack of Pigmentation
38 If a man or woman has spots on the skin of their flesh that are similar to those that can develop into tzara’at, i.e., white spots, 39 the priest must examine them. If there are dark white spots on the skin of their flesh, i.e., darker than any of the previously described four grades of whiteness that can develop into tzara’at, it is nothing more than a lack of pigmentation that has erupted on the skin. He or she is not defiled, even if symptoms characteristic of tzara’at later develop within these spots.
