The fast of Gedaliah is Sunday from dawn until dark, so eat and drink now! Take the opportunity to make a Malave Malka (meal “escorting” the Shabbat queen out) to get yourself ready.
This fast day remembers the assassination of the governor of the Land of Israel after the destruction of the First Temple, Gedaliah ben Achikam. With his death, the small number of Jews left fled.
For the (minor) fast of Gedaliah, we don’t eat or drink. So get your self hydrated and fed today!
