As educated in Judaism as I thought I may have been, Tisha B’Av is a day of commemoration that I have to say, I don’t know enough about. Perhaps it’s because it falls during our summer holidays and the preoccupation with vacation that I just didn’t ever make time for it. With the handy dandy Internet, I was able to find Tisha B’Av 101 on sites like wikipedia.
In observing this fast day, we are reminded of the destruction of the first and second Temples in Jerusalem in addition to other feats in Jewish history. There are prohibitions from work, sexual relations and Torah study, with the exception of texts such as the Book of Lamentations, the Book of Job, portions of Jeremiah and chapters of the Talmud that discuss the laws of mourning.
Hope I filled in the gap on this day for you!
