Passover is the main historical annual festival of the Jews. It commemorates God‘s passing over the houses of the Israelites, when the first born of each Egyptian family was killed (Exodus 12:13).
Passover is sometimes called the “feast of unleavened bread” because during its celebration no leavened bread was eaten or even kept in the house.
See leaven.
Key verse about Passover: then tell them, ‘It is the Passover sacrifice to the Lord, who passed over the houses of the Israelites in Egypt and spared our homes when he struck down the Egyptians.’” Then the people bowed down and worshiped (Exodus 12:27, NIV)
