The eight-day Jewish holiday of Passover is celebrated in the early spring. Passover (Pesach) commemorates the emancipation of the Israelites from slavery in ancient Egypt. Pesach is observed by avoiding leaven, and highlighted by the Seder meals that include four cups of wine, eating matzah and bitter herbs, and retelling the story of the Exodus. In Hebrew it is known as Pesach (which means “to pass over”). https://www.chabad.org/
