Here are some recent thoughts on Tisha B'av by Sam Nadler for his congregants at Hope of Israel Congregation.
This coming Shabbat (Aug. 1) will be what is traditionally called Shabbat Nachamu ("Comfort") a reprive from the day mourning where Scriptures such as Isaiah 40 ("Comfort ye, Comfort ye my people") are read as part of the Haftarah portions. It is interesting to note that in some traditions Tisha b'Av was to be the day of the birth for the Messiah. Why? Because out of tragedy comes the greatest joy.
I (Matt) will be using the occasion this Shabbat to speak from Jer. 31:35-37. Sam and Miriam will be in Los Angeles ministering at ben David Congregation.
