Fast of the Firstborn


Fast of the Firstborn ; is a unique fast day in Judaism which usually falls on the day before Passover. Usually, the fast is broken at a siyum celebration, which, according to prevailing custom, creates an atmosphere of rejoicing that overrides the requirement to continue the fast. Unlike all other Jewish fast days, only firstborn children are required to fast on the Fast of the Firstborn.
This fast commemorates the salvation of the Israelite firstborns during the Plague of the Firstborn, when, according to Exodus : "...God struck every firstborn in the Land of Mitzrayim...."

Origins

The primary source quoted for this custom is Tractate Soferim 21:3, where it is stated that firstborns fast "in commemoration of the miracle that they were saved from the Plague of the Firstborn." Rabbeinu Asher and Rabbeinu Aharon HaKohein quote the Jerusalem Talmud as an additional source for the fast.
Rabbi Yehuda Grunwald suggests that the firstborn Israelites fasted in trepidation in advance of the Plague of the Firstborn; despite a divine guarantee of safety, they felt a need to fast in repentance to achieve greater divine protection. Rabbi Grunwald thus posits that this was the precedent for the Fast of the Firstborn.

Meaning of the fast

Fasts in Judaism can have a number of purposes, including atonement for sins; commemorative mourning, and commemorative gratitude.
The Fast of the Firstborn incorporates commemorative gratitude for salvation from the Plague of the Firstborn, as detailed above.
According to Rabbi Jacob Emden, the Fast of the Firstborn also commemorates the salvation of the Jews from the plot of Haman. This is because Haman advanced his plot on the thirteenth of Nisan, and Queen Esther reacted by instructing all Jews of Shushan to undertake a three-day fast beginning the next day, the fourteenth of Nisan. For this reason, even some non-firstborns maintain the custom to fast on the fourteenth of Nisan.
According to Rabbi Shlomo Zalman Auerbach, the Fast of the Firstborn also includes an aspect of mourning: firstborns fast to mourn the loss of their priestly status which had initially been granted them on the fourteenth of Nisan. Furthermore, during the Temple period, this loss was most profoundly felt on the fourteenth of Nisan, which was the busiest day of the year for the Temple priests and Levites.

Qualifications for fasting

There is disagreement among the early halakhic authorities as to who qualifies as a firstborn for purposes of the Fast of the Firstborn. All authorities agree, however, to the conditions of halakhic adulthood and sanity, preconditions for all positive mitzvot, to obligate one to fast..
According to the Bayit Chadash, the Sefer Agudah, and arguably the Maharil, both men and women are obligated to fast. This is based upon the Midrash, which states that both men and women among the firstborn Egyptians perished in the plague. Following a precedent common in Jewish commemorative rituals, the above authorities ruled that all those who were miraculously saved should participate in commemoration. Since both men and women died from the plague, all firstborn Jewish men and women alive at that time are considered to have been miraculously saved. The Rema and the Vilna Gaon rule that women are exempt from the fast. As the Book of Exodus mentions the biblical commandment of Redemption of the Firstborn as commemorative of the salvation of Jewish firstborns in Egypt, and as this command only applies to firstborn males, the Rema and the Vilna Gaon rule similarly that only males are obligated to fast. Common practice is that only males fast.
While a firstborn to both parents, or a firstborn to only the mother, must fast according to all authorities, there is a dispute among the early halakhic authorities regarding the status of a firstborn to only the father. The Shulchan Aruch codifies that a firstborn to only the father is obligated to fast, while most printings of the Arba'ah Turim indicate that such a person would be exempt. Common practice follows the Shulchan Aruch.
Typically, if the oldest in the family died, the next oldest is not required to fast. However, if the oldest child had died within 30 days of birth, the next oldest is required to fast..
Many authorities, including the Rema, note the custom that the father of a firstborn should fast on his child's behalf until the child reaches halakhic adulthood. The Rema rules that if the father is a firstborn himself, the mother should fast on behalf of the child. The Mateh Moshe and Maharil dispute this and rule in such a scenario that the mother need not fast. The Magen Avraham rules that it is appropriate to follow the lenient opinion if fasting causes the mother excessive discomfort or if she is pregnant or nursing, but he adds that a mother who begins following the former opinion must maintain that custom and fast in subsequent years.
The Sh'vut Ya'akov rules that the above-cited custom of the father fasting for the child goes into effect as soon as the child is born, except where the child is born after chatzot ha'laila on the 14th of Nisan of that year. The Korban N'tan'el disagrees. He writes that the custom only goes into effect from the time the child is 30 days old. This relates, again, to the command to redeem the firstborn, which does not go into effect until the child is 30 days old.
There is some discussion among the poskim regarding whether a firstborn born through caesarean section is required to observe this fast, given that he is not obligated in the Redemption of the Firstborn. The Chok Ya'akov suggests that such a firstborn may be required to fast, while the Kaf HaChayyim rules that he need not fast. To circumvent this question, as well as dispute regarding a firstborn non-Jew who converts to Judaism, Rabbi Yosef Shalom Elyashiv suggests that such firstborns participate in a seudat mitzvah''.

Duration of the fast

As with most Jewish fast days, the fast begins at dawn. The common practice is that it is subsequently broken in the morning at a seudat mitzvah following a siyum. If the fast is not broken at a seudat mitzvah, there is a dispute among halakhic authorities regarding the duration of the fast. Normally, all Jewish fasts continue until nightfall. However, the presence of a fast immediately before a holiday presents a unique quandary. Normally, one may not enter a Shabbat or Yom Tov in a state of fasting. The Talmud discusses what one should do when a formal fast day falls directly before Shabbat or Yom Tov. The sages of the Talmud are divided over two options: Either one should break the fast shortly before sundown, or one should fast through nightfall, regardless. Since the Talmud arrives at no clear conclusion, disagreement arose among halakhic authorities. The Maharil rules that the fast continues until nightfall, while others rule that it should be broken before sundown.

Breaking the fast

In modern times, however, this fast is rarely observed, as most firstborns opt to attend a siyum instead. This is considered a legitimate form of "breaking" the fast, and therefore the firstborn may eat during the rest of the day.
The Mishnah Berurah quotes three opinions regarding circumstances in which the fast may be broken. According to the first, a healthy individual must fast if he can sustain the fast without undue suffering and without any subsequent weakening that would affect his ability or inclination to heartily partake of his Passover Seder meal. According to the second custom, the fast may be broken at any festive meal celebrating a circumcision or a redemption of the firstborn. According to the third custom, based upon the Maharshal, the fast may even be broken at a seudat mitzvah for a siyum celebrating the completion of study of a tractate of Talmud. The latter custom is commonly observed.
If a firstborn attending a siyum does not hear the completion of the tractate, or if he does not understand what he hears, or if he is in the shiva period of mourning and is thus forbidden from listening to the Torah material being taught, some authorities rule that subsequent eating would not qualify as a seudat mitzvah and he would therefore be forbidden to break his fast. Other authorities allow a firstborn to break his fast under such circumstances. The Minchas Yitzchak suggests that a firstborn in such a position should at least try to contribute to the siyum in some way, such as by sponsoring or helping to prepare the meal.
In order to break one's fast on a seudat mitzvah, many authorities rule that one must partake of at least a kotevet of food or a melo lugmav of liquid at the seudah. Other authorities rule that a firstborn need not eat anything at the siyum itself, and that he may break his fast anytime after the siyum.
Rabbi Moshe Feinstein extends the possibility of breaking the fast to include even breaking it at a festive meal celebrating the completion of any mitzvah that required regular, continual involvement. According to these authorities, such a meal would be considered a seudat mitzvah of adequate caliber to exempt one from continuing the fast.
Additionally, the Mordechai quotes the ruling of his father-in-law Rabbeinu Yechiel that firstborns need not fast at all on the day before Passover; firstborns need only limit their diet to snacks. The Mishnah Berurah states that it is appropriate for a weak individual to follow this ruling.

When Passover begins after Shabbat

If the day before Passover falls on Shabbat, most authorities rule that the fast is set for the previous Thursday, and this has become common practice. This is because it is forbidden to fast on Shabbat, and fasts are preferably not set for Friday. In such a scenario, the ritual of Bedikas Chametz is set for Thursday night. Normally, it is forbidden to eat before conducting the Bedikas Chametz. However, for a firstborn who is fatigued or uncomfortable from the fast, the Mateh Moshe and Maharil rule that some food may be eaten before the search or that another person may be appointed to perform the search on behalf of the firstborn.
Rabbi Moshe Feinstein raises the possibility, based on the Rema that one who breaks the adjusted Thursday fast might be required to fast on Friday, as perhaps the fast is considered to have been moved to whichever earlier day is more appropriate, and not to Thursday specifically. Since there are many opinions that dispute the Rema, Rabbi Feinstein writes that, practically speaking, one should not fast on Friday in such circumstances. This rationale may be based on the above cited Korban N'tan'el, who writes that excessive strictures regarding keeping the Fast of the Firstborn should not come at the expense of possibly fasting unnecessarily during the month of Nisan.
The above halakhic quandary is avoided completely if a firstborn fasts the entire day on Thursday. However, Rabbi Feinstein makes no mention of this requirement. In order for a firstborn to comply with the ruling of the Rema, the Piskei T'shuvot suggests participating in a second siyum on Friday, while Rabbi Tzvi Pesach Frank suggests partaking on Friday of leftovers from the previous day's siyum.

Status of the fast

In halakha, there are two general types of fast: the communal fast and the individuals' fast. Among other differences between the two, a special prayer is added by the Chazzan on communal fasts whenever both ten fasting individuals congregate and the Chazzan is fasting. While the Magen Avraham treats the fast as an individuals' fast, the Shiyurei K'nesset Ha-G'dolah, the P'ri Chadash, and the Or Zaru'a view it as a communal fast. To avoid the practical implications of the controversy, the Mishnah Berurah suggests that a firstborn should not serve as Chazzan on the day of the fast.
Additionally, this fast differs from most other fasts established in the Jewish calendar in that this fast is not indicated in the Hebrew Scriptures. This lessens the severity of the fast, and someone who experiences significant discomfort as a result of fasting may break his fast.

Modern practice

The custom of the Fast of the Firstborn is today observed nearly universally throughout Orthodox Ashkenazic communities. However some Sefardic and Mizrahi communities have not fully adopted the custom. It is not traditionally observed by Yemenite Jews and its practice was discouraged by Moroccan-Israeli rabbi Joseph Messas.
Amongst Conservative Jews, the custom is endorsed by various communities and cited positively in their responsa.
