Chamar Medinah

Five tragedies occurred on Tisha B’Av. It was decreed that those who left Egypt would not enter the land of Israel, the first and second Temples were destroyed, the city of Betar was captured with thousands massacred, and Turnus Rufus plowed the site of the razed Temple. Consequently, Tisha B’Av was declared a day of national mourning and a fast day.
