The opening as it read in 2005

Fast of the Firstborn (or Ta'anit B'chorot/B'chorim ) is a unique Jewish fast day which usually falls on the day before Passover .1 The fast's name commemorates the salvation of the Jewish firstborns during the plague of the firstborn (according to the Book of Exodus , the tenth of ten plagues wrought upon ancient Egypt prior to the Exodus of the Children of Israel ), when, according to Exodus (12:29): "...God struck every firstborn in the Land of Mitzrayyim (ancient Egypt)...." Unlike most Jewish fast days, only firstborns have the custom to fast on the Fast of the Firstborn .2
