“Tisha B’Av is a day of mourning and repentance on which we recall the destruction of the First and Second Temples, and other tragic events in Jewish history that took place on this day.

By carefully observing the laws and customs instituted by our Sages, we are able to feel the full impact of what we have lost. We also come to contemplate the individual and national shortcomings, which have prolonged our exile, and renew our personal and collective effort to merit the building of the Third Temple.”
