This Shabbat before תשעה באב Tisha B'Av - the Ninth of Av, (Thursday, July 27), is called שבת חזון, Shabbat Chazon - the 'Shabbat of Vision,' because of the Haftora which is read from the first chapter of the Book of Yeshayahu / Isaiah, which begins "Chazon Yeshayahu - (the vision of Yeshayahu...)". In it, he prophesies about the destruction of Yerushalayim and the Beit Hamikdash.
The three Haftorot of the three weeks preceding the Ninth of Av, are called the — שלש דפורענותא - the "Three
(Haftorot) of Punishment."
This week we study Chapter 2 of Pirkei Avot - "Ethics of the Fathers"
