Passover or Pesach in Hebrew is one of the most important Jewish festivals. Passover marks the day when Moses freed the children of Israel from slavery in Egypt and the celebrations last seven to eight days.
After Moses went to ask the Pharaoh multiple times to release the Israelites and the Pharaoh refused, Moses warned that terrible plagues would descend on Egypt by God if he did not release them. The ten plagues were: blood, frogs, gnats, flies, blight of livestock, boils, hail, locusts, darkness and death of the first-born. Death of the first-born was the final plague and God told Moses for the Israelites to mark their doorposts with lamb’s blood so that God could ‘pass over’ their houses and spare them from the plague, hence the name Passover. The Pharaoh told Moses and the Israelites that should leave at once and they left with such haste that their bread did not have time to rise. This is the reason that Jewish people eat unleavened bread call Matzah during Passover.
