Passover, or Pesach in Hebrew, is one of the Jewish religion’s most sacred and widely observed holidays. In Judaism, Passover commemorates the story of the Israelites’ departure from ancient Egypt, which appears in the Hebrew Bible’s books of Exodus, Numbers and Deuteronomy, among other texts. Jews observe the weeklong festival with a number of important rituals, including a traditional Passover meal known as a seder, the removal of leavened products from their home, the substitution of matzo for bread and the retelling of the exodus tale.
