ועיניתם את נפשותיכם

And the LORD spoke unto Moses, saying: Speak unto the children of Israel, saying: In the seventh month, in the first day of the month, shall be a solemn rest unto you, a memorial proclaimed with the blast of horns, a holy convocation. Ye shall do no manner of servile work; and ye shall bring an offering made by fire unto the LORD. And the LORD spoke unto Moses, saying: Howbeit on the tenth day of this seventh month is the day of atonement; there shall be a holy convocation unto you, and ye shall afflict your souls; and ye shall bring an offering made by fire unto the LORD. And ye shall do no manner of work in that same day; for it is a day of atonement, to make atonement for you before the LORD your God. For whatsoever soul it be that shall not be afflicted in that same day, he shall be cut off from his people. And whatsoever soul it be that doeth any manner of work in that same day, that soul will I destroy from among his people. Ye shall do no manner of work; it is a statute for ever throughout your generations in all your dwellings. It shall be unto you a sabbath of solemn rest, and ye shall afflict your souls; in the ninth day of the month at even, from even unto even, shall ye keep your sabbath.

Rav Yirmeya bar Abba said: There is no completely stringent communal fast in Babylonia, except for the Ninth of Av alone. All other fasts, even those which are fixed and routine for the community, are treated as individual fasts, with regard to both the customs of the fast itself and the halakhot of who is obligated to fast. Rav Yirmeya bar Abba said that Reish Lakish said: A Torah scholar is not permitted to sit in observance of a fast, due to the fact that his fasting reduces his strength for the heavenly service of Torah study and mitzvot.

as though a sacred object is immersed in his bowels, which he may not damage, as it is stated: “The sacred is in your midst; and I will not come into the city” (Hosea 11:9). This statement indicates that it is prohibited to take a fast upon oneself. The Gemara answers: This is not difficult. This first ruling, that one who fasts is sacred, is referring to a case where he is able to distress himself without causing bodily harm. That second ruling, that one may not overly burden his body, deals with a situation when he is unable to distress himself while avoiding all harm, and he proceeds to fast nevertheless. Reish Lakish said: One who fasts is called pious, as it is stated: “The pious man does good [gomel] to his own soul; but he who troubles his own flesh is cruel” (Proverbs 11:17). The verb gomel can also mean weaning, or abstaining from unnecessary pleasure. Accordingly, Reish Lakish derives from this verse that one who abstains from food is called pious. Similarly, Rav Sheshet said: This student of a Torah academy who sits in observance of a fast has let a dog eat his portion. Since his fast weakens him and prevents him from studying Torah, it is considered as though a dog ate his meal, as the student derived no benefit from it.

Rabbi Zeira said that Rav Huna said: With regard to an individual who took a fast upon himself, even if he ate and drank the entire night, on the following day he prays in the Amida the prayer of a fast, which begins: Answer us on the day of our fast. If after completing his fast he slept in his fast, i.e., he continued fasting throughout the night, he does not pray the prayer of a fast the next morning. Rav Yosef said: What does Rav Huna maintain in this regard? Does he hold that one does not fast for only a few hours, i.e., that fasts that do not last from daybreak until nightfall are not considered fasts at all, and therefore these extra hours of the night are not part of his fast, or perhaps he holds that one does fast for a few hours, but one who fasts for a few hours does not pray the prayer of a fast? Abaye said to Rav Yosef: Actually, Rav Huna holds that one does fast for hours, and one who fasts for a few hours does pray the prayer of a fast. But it is different here, as there are hours of the night that he did not take upon himself at the outset. Since one must take an individual fast upon himself beforehand, if he merely continues his fast into the night, these extra hours are not part of his obligation, and therefore he does not add the special prayer for a fast, Aneinu, on the following morning. § The Gemara relates: Mar Ukva happened to come to the city of Ginzak. The inhabitants of Ginzak, among other matters, asked him three questions to which he did not know the answer: First, does one fast for hours, or does one not fast for hours? Mar Ukva did not have an answer readily available. Second, are the clay jars belonging to gentiles, which have been used for storing wine, permanently prohibited, or can they be rendered permitted? He did not have an answer readily available. Thirdly, in what garments did Moses serve all seven days of inauguration, as the acting priest when Aaron and his sons were initiated into the priesthood? Once again, he did not have an answer readily available. Mar Ukva went and asked these questions in the study hall. They said to him: The halakha is: One fasts for hours, and he even prays the prayer of a fast. And the halakha is that the jars belonging to gentiles are permitted after they have not been used at all for twelve months. Finally, in what garments did Moses serve all seven days of inauguration? He did not serve in his own clothes, nor in the regular priestly garments, but in a special white cloak. Rav Kahana taught: Moses served in a white cloak that does not have a hem. Rav Ḥisda said:

Cry aloud, spare not, Lift up they voice like a horn, And declare unto My people their transgression, And to the house of Jacob their sins. Yet they seek Me daily, And delight to know My ways; As a nation that did righteousness, And forsook not the ordinance of their God, They ask of Me righteous ordinances, They delight to draw near unto God. ’Wherefore have we fasted, and Thou seest not? Wherefore have we afflicted our soul, and Thou takest no knowledge?’— Behold, in the day of your fast ye pursue your business, And exact all your labours. Behold, ye fast for strife and contention, And to smite with the fist of wickedness; Ye fast not this day So as to make your voice to be heard on high. Is such the fast that I have chosen? The day for a man to afflict his soul? Is it to bow down his head as a bulrush, And to spread sackcloth and ashes under him? Wilt thou call this a fast, And an acceptable day to the LORD? Is not this the fast that I have chosen? To loose the fetters of wickedness, To undo the bands of the yoke, And to let the oppressed go free, And that ye break every yoke? Is it not to deal thy bread to the hungry, And that thou bring the poor that are cast out to thy house? When thou seest the naked, that thou cover him, And that thou hide not thyself from thine own flesh? Then shall thy light break forth as the morning, And thy healing shall spring forth speedily; And thy righteousness shall go before thee, The glory of the LORD shall be thy rearward.
