Passover and the Exodus are two closely related events in Judaism that commemorate the liberation of the Israelites from slavery in ancient Egypt. Passover celebrates the story of God helping the Israelites escape Egypt through ten plagues and sparing their firstborn sons. The Exodus refers to the actual departure of the Israelites from Egypt across the Red Sea under the leadership of Moses. Both events involve God freeing the Israelites from bondage and are remembered through rituals, prayers, and the retelling of the biblical story during the Jewish holiday of Passover.
