Tisha B'Av Rituals & Practices
Tisha B'Av, the ninth of the month of Av, is a day of mourning for Jews. It is the day Jews remember the destruction of both Temples that once stood in Jerusalem as well as a number of other tragedies that have befallen the Jewish people over the course of history.
A three-week mourning period preceding Tisha B'Av begins on the 17th day of the month of Tammuz. According to the Mishnah, this was the day the Romans succeeded in breaching the walls of Jerusalem in 70 C.E.; the Mishnah also mentions other tragic events that occurred on this day in Tammuz. This three-week period leading up to the major fast of Tisha B'Av is called "Bayn Ha-Metsarim"--"in the Straits." Traditional Jews do not get married or celebrate other joyous festivities in these three weeks.
Before the Holiday
Nine days prior to Tisha B'Av, a new period of more intense mourning begins. Traditional Jews do not eat meat, cut their hair, or wash their clothes unless they are to be worn again during the nine days. All these actions are considered signs of joy or luxury inappropriate for this time of mourning. Reform, Reconstructionist, and Conservative Jews adopt a varied range of these practices.
The Shabbat immediately preceding the festival is Shabbat Hazon (vision). The name derives from the haftarah (prophetic reading) for the day. Taken from Isaiah 1, the reading describes Isaiah's vision of national disaster befalling the Israelites because of their sins.
