A person who removes the signs of impurity, whether all of them or part of them, or who burns the healthy flesh in a baheret, whether partially or entirely, or who removes an entire blemish from his flesh, a garment, or a building, violates a negative commandment, as Deuteronomy 24:8 states: "Be very careful with regard to a tzara'at blemish, to watch it carefully, and to act according to everything that the priest, the Levites, will instruct you, as you were commanded, you shall heed." Implied is that one should not remove hair nor cut off any sign. This applies before the priest comes for an initial examination, after the person has been isolated, after he has been deemed definitively impure, or after he has been sent away as pure. He is not, however, liable for lashes unless his acts are effective. If his acts are not effective, he is not liable for lashes. What is implied? If a person had a baheret with three white hairs and he pulled out one or he burnt a portion of the healthy flesh in a baheret, but a lentil-sized portion remained, he is not liable for lashes, because he is impure, as was his status previously. Similar laws apply in all analogous situations. He is, however, given stripes for rebellious conduct. Similarly, one who shaves the hairs next to a netek is liable for lashes, as Leviticus 13:33 states: "He shall not shave the netek." He is not liable unless he shaves the entire area around the netek with a razor. It is permitted for a person afflicted with tzara'at to carry a pole on his shoulder on which there is a tzara'at blemish or to tie palm bast on his foot on which there is a blemish. If the signs of impurity are removed, they are removed, provided he does not have the intent of removing them.
A person who removes signs of impurity or who burns healthy flesh before the inspection performed by a priest is pure. Similarly, if he does so in the days of his isolation, he will be considered pure after the days of his isolation. If, however, he removed them after he was deemed definitively impure because of them, he remains impure as was his status. He cannot regain purity unless the tzara'at covers his entire body or unless his baheret becomes smaller than a gris.
When a person cuts off his entire baheret unintentionally, he is pure. Different rules apply if he cut it off intentionally. If he cut off all the healthy flesh surrounding the baheret, even a hair's width, he can never become pure. If he cut it off exactly, he cannot regain purity unless the baheret covers his entire body.
When one pulls out one white hair and the second fell off on its own accord, the person is pure. If there were three and he pulled out two and one fell off on its own, he remains impure. If there was a portion of healthy flesh in a baheret the size of a lentil and one burnt half of it and half disappeared, he is pure. If the healthy flesh was larger than a lentil, one burnt off the part greater than a lentil and the lentil sized portion disappeared naturally, he is pure. If he burnt off the portion the size of a lentil and the remainder disappeared, he is impure.
🚫 Do Not Remove Signs
It is a negative commandment to remove signs of tzara'at impurity (pull out white hairs, burn michyah, cut off the blemish) — at any stage: before examination, during isolation, during declared impurity, or after release. One is only liable for lashes if the action is effective in changing the person's status. Shaving the area around a netek is also a Torah prohibition. Circumcision overrides this prohibition when a blemish is on the foreskin.
When a person has a baheret on his foreskin, he should be circumcised even though the circumcision is not being performed on the designated day. The rationale is that the performance of a positive commandment supersedes the observance of a negative commandment in all instances. If the person was circumcised and the removal of the foreskin also caused the removal of the sign that caused him to be deemed impure, he is obligated to bring the sacrifices of a person becoming purified from tzara'at.
⚖️ Removal Effects
Removing signs before or during isolation results in purity after the isolation period ends. Removing signs after definitive impurity ruling does not purify — the person remains muchlat. Purification is then only possible if the blemish covers the entire body or shrinks below a gris. Cutting the entire foreskin with an intact baheret creates permanent impurity; exact circumcision requires full-body coverage to achieve purity.
It is a positive commandment for a man afflicted with tzara'at who was deemed as definitively impure to cover his head throughout the time he is impure, he should be cloaked until his lips like a mourner, his clothes should be torn and he must notify those who pass by him that he is impure, as Leviticus 13:45 states: "And the person afflicted with tzara'at who has the blemish shall...." Even a High Priest who becomes afflicted with leprosy covers his head and tears his clothes, for a positive commandment supersedes a negative commandment. He is forbidden to greet others throughout the time he is deemed impure, as a mourner is, as can be inferred from the continuation of the above verse: "he shall cover his lips," i.e., his lips shall be closed together. He may, however, read Scripture, study Mishnah, and elucidate Torah teachings. He is forbidden to have his hair cut and launder his clothes throughout the time he is deemed definitively impure. He must conduct himself with these restrictions even on Sabbaths and holidays. He is, however, permitted to wash, anoint himself, wear shoes, engage in physical intimacy, and have his bed stand upright like other people.
The law is that a person afflicted by tzara'at should have a dwelling alone outside the town, as indicated by Leviticus 13:46: "outside the camp where he dwells." This restriction applies only in walled cities in Eretz Yisrael.
A woman afflicted by tzara'at does not cover her head, rend her garments, or cloak her face. She does, however, dwell outside her town and inform others that she is impure. Indeed, not only those afflicted by tzara'at, but all those who impart impurity to other people are obligated to inform everyone that they are impure so that they will separate themselves from them, as implied by ibid.:45: "'Impure, impure,' he shall call out." That can be interpreted to mean "The impure person shall inform others that he is impure."
A tumtum and an androgynus should cover their heads, rend their garments, and cloak their faces, because their status is in doubt.
🏔️ Metzora's Laws
A declared muchlat must: cover his head, cloak his lips like a mourner, tear his garment, and call out 'impure, impure' to warn passersby. He must live outside the town walls (in walled cities of Israel). He is forbidden to greet others, cut his hair, or launder clothes — but may wash, anoint, wear sandals, and engage in marital relations. These laws apply even on Shabbat.

Impurity Laws: The Metzora as Primary Source of Impurity
The same laws apply to both a person afflicted with tzara'at who is isolated and one who is definitively deemed impure. With regard to impurity, there is no difference between a person afflicted with tzara'at who is isolated and one who is definitively deemed impure except covering one's head, rending one's garments, shaving, and bringing fowl. One who is deemed pure after being isolated is exempt from shaving and bringing fowl, while one who is deemed pure after having been deemed impure has these obligations. Nevertheless, with regard to impurity, they are equal in all matters.
A person afflicted with tzara'at is a primary source of impurity. He imparts impurity to humans and implements through touching them and to earthenware containers when a portion of his body enters their inner space. He imparts impurity to a person when carried by him and an object over which he lies or sits even if there is a stone intervening between him and their surface, as is the law regarding a zav and a zavah. This is derived from Leviticus 13:6: "He shall launder his garments." According to the Oral Tradition, it was taught that he becomes pure with regard to imparting impurity to the objects on which he lies or sits. All of these laws apply equally to one isolated because of tzara'at and one deemed definitively impure].
☣️ Source of Impurity
The metzora is an av ha-tumah (primary source of impurity), imparting impurity through touch, carrying, and entry into a building — even to earthenware containers through airspace. He also conveys impurity through lying/sitting articles (mishkav/moshav) like a zav. The special severity: he defiles everything in a building he enters without touching it, just as his dwelling-place is impure wherever he rests.

🎓 Key Principles
Chapter 10
🚫
Signs Are Legally Protected Torah prohibits tampering with tzara'at signs at any stage of the process — from pre-examination through post-release — because the priest's assessment process depends on the authentic state of the blemish.
🏔️
Isolation Has Behavioral Requirements The declared metzora's mourning-like conduct (covered head, torn garments, warning cries) is not just spiritual — it's a Torah-mandated positive commandment, even for a High Priest.
🏠
Dwelling Outside the Town The metzora must live outside walled cities of Israel — this geographic isolation reinforces that his condition requires complete separation from communal life until the priest declares him pure.
☣️
Building Entry Is Severely Defiling A unique stringency: the metzora defiles everyone and everything in a building he enters — without any touching — making him the most severe source of impurity among living humans.
