Passover

Passover begins on the 15th day of the month of the first month of the Hebrew calendar's festival year according to the Hebrew Bible. In the narrative of the Exodus, the Bible tells that God inflicted ten plagues upon the Egyptians before Pharaoh would release his Hebrew slaves, with the tenth plague being the killing of all of the firstborn, from the Pharaoh's son to the firstborn of the dungeon captive, to the firstborn of cattle. The Hebrews were instructed to mark the doorposts of their homes with the blood of a spring lamb and, upon seeing this, the spirit of the Lord passed over these homes, hence the term "passover".[2] When Pharaoh freed the Hebrews, it is said that they left in such a hurry that they could not wait for bread to rise. In commemoration, for the duration of Passover, no leavened bread is eaten, for which reason it is called "The Festival of the Unleavened Bread".[3] Matza (flat unleavened bread) is the primary symbol of the holiday.
