At sundown on July 28, is the Jewish commemoration of Shabbat Chazon—taking its name from Isaiah 1:1–27, a passage read from the Haftarah, before the mournful fast of Tisha B’Av. “Hear, O heavens, Listen, O earth for the Lord has spoken. I reared children and brought them up but they have rebelled against me.”
Tisha B’Av, the fast of the Ninth of Av, is a day of mourning the tragedies of the Jewish people. On that day, according to tradition, was the destruction of the first and second temples in 586 BC and AD 70.
It's also a day to mourn the loss and exile of millions of Jew. In synagogues, the book of Lamentations will be read, and prayers of mourning recited.
