1The Gemara asks: What is the halakha governing those who are ostracized and lepers, with regard to a haircut? The Gemara answers: Come and hear that which was taught in a baraita : Those who are ostracized and lepers are prohibited from cutting their hair and laundering their clothes.
2It was further taught there: If one who is ostracized dies, the court places stones on his coffin. Rabbi Yehuda says: This does not mean that they pile up a heap of stones over him like the heap of stones that was placed over the grave of Achan (see Joshua 7:26). Rather, the court sends its agents, who place a large stone on his coffin as a symbolic gesture. This comes to teach you that anyone who is ostracized and dies while in his period of ostracism, without seeking to be released from it, the court places stones on his coffin.
3§ The Gemara continues: A mourner is obligated to wrap his head as a sign of mourning, covering his head and face. This is derived from the fact that the Merciful One says to Ezekiel, while he is in mourning: “And cover not your upper lip” (Ezekiel 24:17). God commands Ezekiel not to display outward signs of mourning, which proves by inference that everyone else is obligated to wrap their heads in this manner.
4The Gemara asks: What is the halakha governing a person who is ostracized, with regard to wrapping of the head? Rav Yosef said: Come and hear that which was taught in a baraita about those who were fasting for rain and whose prayers were not answered: And they wrap themselves and sit as those who are ostracized and as mourners, until they are shown mercy from Heaven. This implies that those who are ostracized must wrap their heads like mourners. Abaye said to him: Perhaps one who is ostracized by Heaven is different, as that is more serious than being ostracized by an earthly court.
5The Gemara continues and asks: What is the halakha in the case of a leper with regard to wrapping of the head? Come and hear a proof based upon the verse: “And he shall cover his upper lip” (Leviticus 13:45), from which it may be learned by inference that he is obligated to wrap his head. The Gemara concludes: Indeed, learn from here that this is the case.
6§ The Gemara moves on to another halakha : A mourner is prohibited from donning phylacteries. This is derived from the fact that the Merciful One says to Ezekiel, while he is in mourning: “Bind your headwear [ pe’er ] upon yourself” (Ezekiel 24:17). The word pe’er alludes to phylacteries. Ezekiel was unique in that he was commanded to put on phylacteries while in mourning, which proves by inference that everyone else is prohibited from doing so.
7The Gemara asks: What is the halakha governing one who is ostracized, with regard to phylacteries? The dilemma shall stand unresolved. The Gemara proceeds to its next question: What is the halakha in the case of a leper with regard to phylacteries? The Gemara suggests: Come and hear a proof from the following baraita : The verse states: “And the leper” (Leviticus 13:45); as explained earlier, this comes to include the High Priest in all the halakhot of the leper. The verse states there: “His garments shall be perumim ,” meaning that they shall be rent. The verse continues: “And his head shall be parua ,” and this peria means only growing the hair long; this is the statement of Rabbi Eliezer.
8Rabbi Akiva says: The meaning of these terms is derived through a verbal analogy. The verse states a form of the verb being, with regard to one’s head in the verse: “His head shall be,” teaching that a leper must perform a certain action with his head. And the verse states a form of the verb being with regard to a leper’s garment, in the verse: “His garment shall be.” Just as the term being stated with regard to his garment is referring to an object external to his body, so too, the term being used with regard to his head is referring to an object external to his body. The Gemara derives from this: What, is it not referring to phylacteries, and the verse teaches that it is prohibited for a leper to wear phylacteries?
9Rav Pappa said: No, there is no proof from here, as the verse may be referring to a cap [ kumta ] or a scarf [ sudara ], which people wear on their heads. It is possible to explain that according to Rabbi Akiva, it is prohibited for a leper to wear such headwear because it is excessive adornment.
10§ The Gemara continues: A mourner is prohibited from greeting others or being greeted. This is derived from the fact that the Merciful One says to Ezekiel: “Sigh in silence” (Ezekiel 24:17), implying that aside from what was absolutely essential, he was prohibited from speaking.
11The Gemara asks: What is the halakha governing one who is ostracized with regard to greeting others? Rav Yosef said: Come and hear a proof from a baraita dealing with those who were fasting for rain and whose prayers were not answered. These people were prohibited from greeting one another, as people who are reprimanded by the Omnipresent. This indicates that those who are ostracized must not greet each other, just as mourners may not greet each other. Abaye said to him: Perhaps one who is ostracized by Heaven is different, as that is more serious than being ostracized by an earthly court.
12The Gemara continues and asks: What is the halakha concerning a leper with regard to greeting others? The Gemara suggests: Come and hear a proof from the following baraita : The verse states: “And he shall cover his upper lip” (Leviticus 13:45). This means that his lips should be stuck together, that he should be like one who is ostracized and like a mourner, and he is prohibited from greeting others or being greeted. The Gemara concludes: Indeed, learn from this that this is so.
13The Gemara asks: If this is the case, then we should also resolve the question asked above with regard to one who is ostracized and say that such a person is prohibited from offering greetings. Rav Aḥa bar Pineḥas said in the name of Rav Yosef: Does it explicitly teach that a leper is prohibited from greeting others, like one who is ostracized? It teaches only that he should be treated like one who is ostracized and like a mourner, i.e., he should be like them with regard to other things, and that he is also prohibited from greeting others. This being the case, no proof can be derived from here with regard to whether or not one who is ostracized may offer greetings.
14§ The Gemara moves on to a new topic: A mourner is prohibited from studying words of Torah. This prohibition is derived from the fact that the Merciful One says to Ezekiel: “Sigh in silence” (Ezekiel 24:17). Ezekiel was commanded to be silent and not discuss even Torah matters.
15The Gemara asks: What is the halakha concerning one who is ostracized with regard to speaking words of Torah? Rav Yosef said: Come and hear that which was taught in the following baraita : One who is ostracized may teach Torah to others, and others may teach him Torah. Similarly, he may be hired for work by others, and others may be hired by him.
16One who has been excommunicated, which is a more severe form of ostracism, may not teach Torah to others and others may not teach him. He may not be hired by others, and others may not be hired by him. However, he may study by himself, so that he will not interrupt his study entirely and forget everything he knows. And he may build a small store for his livelihood, so that he can earn enough money to cover his most basic needs, but not more.
17And Rav said: What is the small store referred to here? This is referring to selling water in the valley of Aravot, where no water was to be found. One selling water there could earn a small income. The Gemara concludes: Indeed, learn from this baraita that one who is ostracized is permitted to study Torah.
18The Gemara asks: What is the halakha with regard to a leper speaking words of Torah? The Gemara answers: Come and hear that which is taught in a baraita : It is written: “And you shall impart them to your children and your children’s children; the day that you stood before the Lord your God in Horeb” (Deuteronomy 4:9–10). Just as there, the revelation at Sinai was in reverence, fear, and trembling, so too, here, in every generation, Torah must be studied in a similar fashion.
19From here the Sages stated: Zavim , lepers, and those who had intercourse with menstruating women despite their severe ritual impurity are permitted to read the Torah, Prophets, and Writings, and to study midrash, Talmud, halakhot , and aggada . But those who experienced a seminal emission are prohibited from doing so. The reason for this distinction is that the cases of severe impurity are caused by ailment or other circumstances beyond one’s control; as a result, they do not necessarily preclude a sense of reverence and awe as one studies Torah. However, a seminal emission usually occurs due to frivolity and a lack of reverence and awe, and it is therefore inappropriate for one who experiences a seminal emission to engage in matters of Torah. The Gemara concludes: Indeed, learn from this that a leper is permitted to study words of Torah.
20§ The Gemara proceeds to discuss another issue: A mourner is prohibited from laundering his clothes, as it is written: “And Joab sent to Tekoa, and fetched from there a wise woman, and said to her, I pray you, feign yourself to be a mourner, and put on now mourning apparel, and do not anoint yourself with oil, but be as a woman that had a long time mourned for the dead” (II Samuel 14:2).
21The Gemara asks: What is the halakha concerning laundering with regard to those who are ostracized or lepers? Come and hear that which is taught in a baraita : Those who are ostracized or lepers are prohibited from cutting their hair or laundering their clothes. The Gemara concludes: Indeed, learn from here that they are prohibited from laundering their clothes.
22The Gemara continues: A mourner is obligated to rend his clothes. This is derived from the fact that the Merciful One says to the sons of Aaron: “Neither rend your clothes” (Leviticus 10:6), which proves by inference that everyone else, all other mourners, are obligated to rend their clothes.
23The Gemara asks: What is the halakha of rending clothes with regard to one who is ostracized ? No answer is found, and the question shall stand unresolved.
24The Gemara continues: What is the halakha concerning a leper with regard to rending? Come and hear that which is taught in the following baraita : The verse states: “His garments shall be rent” (Leviticus 13:45), meaning that they shall be torn. The Gemara concludes: Indeed, learn from here that this is the case.
25§ The Gemara moves to a different issue: A mourner is obligated to overturn his bed, so that he sleeps on the underside of it, as bar Kappara taught a baraita that states:
