Moed Katan 15A

מנודין ומצורעין מה הן בתספורת? תא שמע: מנודין ומצורעין אסורין לספר ולכבס.

The Talmud asks: What is the halakha governing those who are ostracized and lepers, with regard to a haircut? The Talmud 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.

מנודה שמת, בית דין סוקלין את ארונו. רבי יהודה אומר: לא שיעמידו עליו גל אבנים כגלו של עכן, אלא בית דין שולחין ומניחין אבן גדולה על ארונו, ללמדך שכל המתנדה ומת בנידויו ⁠— בית דין סוקלין את ארונו.

It was further taught there: If one who is ostracized dies, the court places stones on his coffin. R' 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.

אבל חייב בעטיפת הראש. מדקאמר ליה רחמנא ליחזקאל: ״ולא תעטה על שפם״, מכלל דכולי עלמא מיחייבי.

§ The Talmud 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 God 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.

מנודה מהו בעטיפת הראש? אמר רב יוסף, תא שמע: והן מתעטפין ויושבין כמנודין וכאבלים עד שירחמו עליהם מן השמים. אמר ליה אביי: דלמא מנודה לשמים שאני, דחמיר.

The Talmud 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.
