Holidays: The Four Fasts – Fasts of National Mourning

Shalom, everyone! There are Four Fasts mentioned in Zechariah 8:19 which the House of Yehudah (Judah) observed annually in ancient times to mourn the destruction of the Holy Temple and Jerusalem by the Babylonians in the 6th century BCE. Zechariah prophesies that these solemn occasions will one day become joyous occasions for the House of Yehudah, provided they willingly walk in the way of honesty and integrity:

“Thus said the LORD of Hosts: The fast of the fourth month, the fast of the fifth month, the fast of the seventh month, and the fast of the tenth month shall become occasions for joy and gladness, happy festivals for the House of Judah; but you must love honesty and integrity.”

Please note that none of the Four Fasts were commanded by YAH, however, He does acknowledge them as seen in the above verse from the Tanakh. These fasts were instituted by the remnant of Yehudah who went into exile in Babylon, to remind them of the heavy price of their transgressions against the Torah. The Four Fasts are not days of rest – work is permitted. These fasts are voluntary and present additional opportunities during the year to pause and reflect upon the consequences of our actions

If observing any of the Four Fasts, please note that no eating, drinking or other pleasurable activities are permitted on these days. With the exception of the Fast of the Fifth Month (Tzom HaChamishi, Tisha B’Av), these fasts are considered minor fasts, that is, they are in effect from dawn to dusk, about 12-13 hours. The Fast of the Fifth Month (Tzom HaChamishi, Tisha B’Av) however, is a full 25-hour fast.
