Every year Jewish people all over the world celebrate the holiday of Passover by holding a seder in their homes. The word, "seder," in Hebrew means "order," and there is a specific order in which the Passover Seder occurs. When Hannah's mother in The Devil's Arithmetic, tells Hannah that Passover is about remembering, this is what she is talking about. During the seder, the Passover story is retold. Jews are commanded to tell the story in order to remember their past. God saved the Jewish people from slavery in Egypt over two and a half thousand years ago and after forty years in the desert, God brought them to the land of Israel. During Passover, Jews remember and celebrate their redemption.
