Luke 22:1:“Now the feast of unleavened bread drew nigh, which is called the Passover.”
The Passover, also known as the Feast of Unleavened Bread, is a High Holy Day. This convocation serves to bring into remembrance the day when the Children of Israel were delivered from ancient Egypt (house of bondage). The name “Passover” was given to this holy day because the Most High brought the curse of the slaying of the firstborn upon Egypt. The blood which was sprinkled on the two side posts would cause the destroyer to “passover” the homes of those that kept this ordinance (Exodus 12:12-13, 21-23). This ordinance was to be taught and recalled by every generation.
Exodus 12:26-27: “And it shall come to pass, when your children shall say unto you, What mean ye by this service?” (27) “That ye shall say, It is the sacrifice of the LORD’S passover, who passed over the houses of the children of Israel in Egypt, when he smote the Egyptians, and delivered our houses. And the people bowed the head and worshipped.”
