Tshá b'Av - Destruction of the Temple

The fast commemorates the destruction of the First and Second Temples. Those two events occurred about 656 years apart, but on the same date.

In connection with the fall of Jerusalem, three other fast-days were established at the same time as the Ninth Day of Av: these were the Tenth of Tevet, when the siege began; the Seventeenth of Tammuz, when the first breach was made in the wall; and the Third of Tishrei, known as the Fast of Gedaliah, the day when Gedaliah was assassinated (II Kings 25:25; Jeremiah 41:2).

From Zechariah 7:5, 8:19 it appears that after the building of the Second Temple the custom of keeping these fast-days was temporarily discontinued. Since the destruction of Jerusalem and of the Second Temple by the Romans, the four fast-days have again been observed.

The five calamities

According to the Mishnah (Taanit 4:6), five specific events occurred on the ninth of Av that warrant fasting:

The twelve scouts sent by Moses to observe the land of Canaan returned from their mission. Two of the scouts, Joshua and Caleb, brought a positive report, but the others spoke disparagingly about the land which caused the Children of Israel to cry, panic and despair of ever entering the "Promised Land". For this, they were punished by God that their generation would not enter the land. Because of the Israelites' lack of faith, God decreed that for all generations this date would become one of crying and misfortune for their descendants, the Jewish people. (See Numbers Ch. 13–14)

The First Temple built by King Solomon and the Kingdom of Judah were destroyed by the Babylonians led by Nebuchadnezzar in 586 BCE and the Judeans were sent into the Babylonian exile.

The Second Temple was destroyed by the Romans in 70 CE, scattering the people of Judea and commencing the Jewish exile from the Holy Land.

Bar Kokhba's revolt against Rome failed in 135 CE. Simon bar Kokhba was killed, and the city of Betar was destroyed.

Following the Roman siege of Jerusalem, the razing of Jerusalem occurred the next year.

According to the Talmud in tractate Taanit, the destruction of the Second Temple began on the ninth and was finally consumed by the flames the next day on the Tenth of Av.

Other calamities

Over time, Tisha B'Av has come to be a Jewish day of mourning, not only for these pre-Talmudic events, but also for later tragedies. There is a custom of assigning Tisha B'Av as the date on which wars affecting Jews began or expulsions and persecutions of Jews occurred, although this dating is not always historically accurate. Regardless of the exact dates of these events, for many Jews, Tisha B'Av is the designated day of mourning for them, and these themes are reflected in liturgy composed for this day.

History

In the long period which is reflected in Talmudic literature the observance of the Ninth Day of Av assumed a character of constantly growing sadness and asceticism. By the end of the second century or at the beginning of the third, the celebration of the day had lost much of its gloom. Rabbi Judah ha-Nasi was in favor of abolishing it altogether or, according to another version, of lessening its severity when the fast has been postponed from Saturday to Sunday (Talmud, Tractate Megillah 5b).

The growing strictness in the observance of mourning customs in connection with the Ninth Day of Av became pronounced in post-Talmudic times, and particularly in the darkest period of Jewish history, from the fifteenth century to the eighteenth.

Maimonides (twelfth century), in his Mishneh Torah, says that the restrictions as to the eating of meat and the drinking of wine refer only to the last meal before fasting on the Eighth Day of Av, if taken after noon, but before noon anything may be eaten (Hilchoth Ta'anith 5:8). Rabbi Moses of Coucy (thirteenth century) wrote that it is the universal custom to refrain from meat and wine during the whole day preceding the Ninth of Av (Sefer Mitzvoth ha-Gadol, Venice ed., Laws of Tishah B'Av, 249b). Rabbi Joseph Caro (sixteenth century) says some are accustomed to abstain from meat and wine from the beginning of the week in which the Ninth Day of Av falls; and still others abstain throughout the three weeks from the Seventeenth of Tammuz (Shulkhan Arukh, Orach Chayim 551).
A gradual extension of prohibitions can be traced in the abstention from marrying at this season and in other signs of mourning. So Rabbi Moses of Coucy says that some do not use the tefillin ("phylacteries") on the Ninth Day of Av, a custom which later was universally observed (it is now postponed until the afternoon). In this manner all customs originally designated as marks of unusual piety finally became the rule for all.

Restrictions in the Days

The main prohibitions associated with fasting

Tisha B'Av is a fast day similar to Yom Kippur. While most other fasts on the Hebrew calendar only last from dawn to nightfall, the Tisha B'Av fast lasts about 25 hours, beginning at sunset on the eve of Tisha B'Av and ending at nightfall the next day. Tisha B'Av also shares four additional prohibitions with Yom Kippur:

The five main prohibitions on Tisha B'Av are:

No eating or drinking
No washing or bathing
No application of creams or oils
No wearing of leather shoes
No sexual relations or displays of physical affection

These restrictions are waived in the case of health issues. For example, those who are seriously ill may eat and drink, in contrast to Yom Kippur, when eating and drinking is allowed only in cases of life-threatening need. (On other fast days almost any medical condition may justify breaking the fast; in practice, since many cases differ, consultation with a rabbi is often necessary.) Ritual washing up to the knuckles is permitted. Washing to cleanse dirt or mud from one's body is also permitted.

Additional customs associated with mourning

Torah study is forbidden on Tisha B'av (as it is considered an enjoyable activity), except for sad texts such as the Book of Lamentations, the Book of Job, portions of Jeremiah and chapters of the Talmud that discuss the laws of mourning.[4]
From the meal immediately before the fast (seudah hamafseket) until noon the next day, it is customary to sit on low stools or on the floor, as is done during shiva. If possible, work is avoided during this period. Electric lighting may be turned off or dimmed, and kinot recited by candle-light. Some sleep on the floor or modify their normal sleeping routine, by sleeping without a pillow, for instance. People refrain from greeting each other or sending gifts on this day. Old prayerbooks and Torahs are often buried on this day.

Customs during the days preceding and following Tisha B'av

The days leading up to Tisha B'Av are known as The Nine Days. Orthodox Jews refrain from eating meat during all or part of this period, and some refrain from pleasurable activities such as going to music concerts or swimming. In the three weeks before Tisha B'Av, some Jews do not cut their hair or shave. Weddings are not held during this period.

Although the fast ends at nightfall, it is customary to refrain from eating meat and drinking wine until noon of the following day. According to tradition, the Temple burned all night and most of the day of the tenth of Av.[5]
The laws of Tisha B'Av are recorded in the Shulkhan Arukh (the "Code of Jewish Law") Orach Chayim 552-557.

Services

The scroll of Eicha (Lamentations) is read in synagogue during the evening services. In addition, most of the morning is spent chanting or reading Kinnot, most bewailing the loss of the Temples and the subsequent persecutions, but many others referring to post-exile disasters. These later kinnot were composed by various poets (often prominent rabbis) who had either suffered in the events mentioned or relate received reports. Important kinnot were composed by Elazar ha-Kalir and Rabbi Judah ha-Levi. After the Holocaust, kinnot were composed by the German-born Rabbi Shimon Schwab (in 1959, at the request of Rabbi Joseph Breuer) and by Rabbi Solomon Halberstam, leader of the Bobov Hasidim (in 1984).
In many Sephardic congregations the Book of Job is read on the morning of Tisha B'Av.
