Passover, also called Pesach, is a major Jewish holiday for Rabbinical Judaism, Karaite Judaism, and Samaritanism, one of the Three Pilgrimage Festivals, that celebrates the Exodus of the Israelites from slavery in Biblical Egypt.

The Three Pilgrimage Festivals or Shalosh Regalim, are three major festivals in Judaism—two in spring; Passover, 49 days later Shavuot ; and in autumn Sukkot —when all Israelites who were able were expected to make a pilgrimage to the Temple in Jerusalem as commanded by the Torah. In Jerusalem, they would participate in festivities and ritual worship in conjunction with the services of the kohanim (priests) at the Temple.
