Rabbi L. A. Cassel, spiritual leader of Congregation B’nai Abraham explains the symbolic foods of the Passover Festival in 1964 to pupils of the congregation’s religious school. Matzot, unleavened bread, and other food symbolic of the slavery and freedom of the Israelites occupy the Seder table on the first two nights of the eight-day festival. Children, from left, are Michael Abes holding the Kiddush Cup, Carol Mark, Roberta Hurwitz and Robert Garber, reading the Haggadah, which contains the hymns and prayers of the story of the deliverance out of Egyptian bondage. This year, Passover begins Friday.
