One of the forms of Sara’at (“leprosy”) is called “Netek,” and it manifests itself through the unexplained loss of hair in an area of one’s head of beard. If two yellow hairs grow in the middle of the bald spot that had formed, then the person is declared to have “Netek.” The Torah in Parashat Tazria (Vayikra 13:33) forbids removing these two yellow hairs (“Ve’et Ha’netek Lo Yegale’ah”). A person who experiences this condition is not permitted to remove the hairs in order to avoid being declared a Mesora (person stricken with Sara’at), and must instead follow the procedures required of a person who is determined to have Sara’at. The Sefer Ha’hinuch explains that the Torah issued this command to teach that we must humbly endure punishments which G-d brings upon us, without trying to resist it or thinking that we can somehow prevent G-d’s plan from materializing. The person who experiences a “Netek” infection must accept his condition, and not think that he can escape G-d’s punishment by removing the bodily signs of this status. When a person experiences any sort of malady or other hardship, his response must be to humbly beg G-d for forgiveness and assistance, and not to try to “outsmart” the divine decree. This command applies to both and women, and in all places, but only in the times when there are Kohanim who are proficient in the laws of Nega’im (Sara’at infections) and are thus able to reach decisions as to the status of skin discolorations. Somebody with a “Netek” infection who removes the yellow hairs is in violation of this command and liable to Malkut.
