Day 209: Positive Commandment 112

Sunday, 17 Elul 5786 / August 30, 2026

Positive Commandment 112 (Digest)

Proclaiming Ritual Impurity

"And the person with tzaraat, in whom there is the lesion, his garments shall be torn, his head shall be unshorn, he shall cover himself down to his lips and call out, 'Unclean! Unclean!'"—Leviticus 13:45.

We are commanded to make a metzora recognizable so that people should stay away from him [and thus avoid contracting ritual impurity].

According to our tradition, this mitzvah somewhat applies to all carriers of ritual impurity; they too must make themselves recognizable in order that people keep away from them [though a person with an impurity other than tzaraat need not do all that is stated in the verse above].

Women who suffer from tzaraat are exempt from [most of] this mitzvah, though they do need to cover their face down to their lips and proclaim that they are impure—similar to all other people who are impure [with impurities other than tzaraat].

> The 112th mitzvah is that we are commanded to make a metzora recognizable so that people should keep away from him.

>

>

> The source of this commandment is G‑d's statement;) (exalted be He), "A metzora who has on himself a mark of tzora'as, must tear his clothing, go without a haircut, cover his face down to his lips; and he shall call out, 'Unclean! Unclean!' "

>

>

> The proof;) that this counts as a positive commandment is from the Sifri , which says, "From the verse;) [regarding a k ohen gadol], 'He shall not let his hair grow long nor tear his garments,' I would think that it is forbidden even if he has tzora'as. How would I explain the statement [that a metzora], 'must tear his clothing, go without a haircut' — As referring to everyone except a kohen gadol? The Torah therefore writes ;)], 'who has on himself a mark of tzora'as,' — to tell you that even a kohen gadol 'must tear his clothing' and must 'go without a haircut' [if he has tzora'as]."

>

>

> It is clear that it is a Biblical prohibition for a kohen gadol to tear his clothing or go without a haircut.;) And the general rule is,;) "When you have a positive commandment and a prohibition: if both can be kept, that is best; if not, the positive commandment overrides the prohibition." Since a kohen gadol who is stricken with tzora'as does tear his clothing and grow his hair long, it proves that it must be a positive commandment.;)

>

>

> It has been passed down through the Oral Tradition that people who carry other forms of tumah must also make themselves recognizable in order that people keep away from them. The Sifra says, "Those who are tameh meis; who have had relations with a woman in a state of niddah [and are thereby tameh]; and all others who could make another person tameh — how do we know [that they too must make themselves recognizable]? From the phrase, 'he shall call out, 'Unclean! Unclean!' "

>

>

> This means that any person who is tameh must proclaim that he is tameh,;) i.e., to make a sign to show that he is tameh and will convey tumah to anyone who touches him, in order that people should keep away from him.

>

>

> We have already explained that not all the signs;) for recognizing a metzora are obligatory for women. This is derived from the statement of our Sages,;) "A man must grow his hair and tear his clothing, and a woman must not grow her hair and tear her clothing." She does, however, cover her face down to her lips;) and proclaim that she is tameh, like other people who are tameh.

> See Kapach , 5731, note 40, who holds that a male metzora, since he has visible signs (e.g., torn garments) that indicate his status, does not make a verbal proclamation; the signs themselves serve as notification. A woman, however, as well as those tameh in other ways, have no visual indications (see next footnote), and therefore must give verbal notification.
