Friday, 18 Tammuz, 5783

Moses destroyed the Golden Calf, and re-ascended Mount Sinai to plead G-d's forgiveness for the Jewish people. (Exodus 32:20; Talmud Taanit 30b. See "Today in Jewish History" for Tammuz 16 and Tammuz 17)

During the Three Weeks, from 17th of Tamuz to the 9th of Av, we commemorate the conquest of Jerusalem, the destruction of the Holy Temple and the dispersion of the Jewish people.

Weddings and other joyful events are not held during this period; like mourners, we do not cut our hair, and various pleasurable activities are limited or proscribed. (The particular mourning customs vary from community to community, so consult a competent halachic authority for details.)

Citing the verse (Isaiah 1:27) "Zion shall be redeemed with mishpat [Torah] and its returnees with tzedakah," the Rebbe urged that we increase in Torah study (particularly the study of the laws of the Holy Temple) and charity during this period.
