Meaning of the fast

In Judaism

, and a combination of some or all of these could apply to any given fast. One purpose in fasting is the achievement of atonement for sins and omissions in Divine service. Fasting is not considered the primary means of acquiring atonement; rather, sincere regret for and rectification of wrongdoing is key (see Isaiah
Book of Isaiah
The Book of Isaiah is the first of the Latter Prophets in the Hebrew Bible, preceding the books of Ezekiel, Jeremiah and the Book of the Twelve...

, 58:1-13).

Nevertheless, fasting is conducive to atonement, for it tends to precipitate contrition in the one who fasts (see Joel
Book of Joel
The Book of Joel is part of the Hebrew Bible. Joel is part of a group of twelve prophetic books known as the Minor Prophets or simply as The Twelve; the distinction 'minor' indicates the short length of the text in relation to the larger prophetic texts known as the "Major Prophets".-Content:After...

, 2:12-18). This is why the Bible requires fasting (lit. self affliction) on Yom Kippur
Yom Kippur

, 8:1; ibid. Babylonian Talmud, 81a). Because, according to the Hebrew Bible, hardship and calamitous circumstances can occur as a result of wrongdoing (see, for example, Leviticus, 26:14-41), fasting is often undertaken by the community or by individuals to achieve atonement and avert catastrophe (see, for example, Esther

. The purpose of a fast of mourning is the demonstration that those fasting are impacted by and distraught over earlier loss. This serves to heighten appreciation of that which was lost. This is in line with Isaiah (66:10), who indicates that mourning over a loss leads to increased happiness upon return of the loss:
Be glad with Jerusalem, and exult in her, all those who love her; rejoice with her in celebration, all those [who were] mourners over her.


The third purpose in fasting is commemorative gratitude. Since food and drink are corporeal needs, abstinence from them serves to provide a unique opportunity for focus on the spiritual. Indeed, the Midrash
Midrash

, 46). This dedication is considered appropriate gratitude to God for providing salvation. Additionally, by refraining from such basic physical indulgence, one can more greatly appreciate the dependence of humanity on God, leading to appreciation of God's beneficence in sustaining His creations. Indeed, Jewish philosophy considers this appreciation one of the fundamental reasons for which God endowed mankind with such basic physical needs as food and drink. This is seen from the text of the blessing customarily recited after consuming snacks or drinks:
You are the Source of all blessing, O' Eternal One, our God, King of the universe, Creator of many souls, who gave [those souls] needs for all that which You created, to give life through them to every living soul. Blessed is the Eternal Life-giver.

Furthermore, during the Temple

) for purposes of the Fast of the Firstborn. All authorities agree, however, to the conditions of halakhic adulthood (generally speaking, this is 12 years for a female and 13 years for a male) and sanity, preconditions for all positive mitzvot, to obligate one to fast. (Other rare conditions, such as deaf-muteness, also exempt one from positive mitzvot).

) on the 14th of Nisan of that year.

He writes that the custom only goes into effect from the time the child is 30 days old.

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 (Siddur Pesach K'hilchaso, ibid; Rabbi Yehoshua Menachem Mendel Ehrenberg, Devar Yehoshua 2:81).

) is set for Thursday night. Normally, it is forbidden to eat (starting from nightfall) 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 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 (who eats on Thursday) 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

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
