Passover,

the first of the three great annual festivals of the Israelites celebrated in the month Nisan (March-April, from the 14th to the 21st. (Strictly speaking the Passover only applied to the paschal supper and the feast of unleavened bread followed, which was celebrated to the 21st.) (For the corresponding dates in our month, see Jewish calendar at the end of this volume.) The following are the principal passages in the Pentateuch relating to the Passover: ( Exodus 12:1-51 ; 13:3-10 ; 23:14-19 ; 34:18-26 ; Leviticus 23:4-14 ; Numbers 9:1-14 ; 28:16-25 ; 16:1-6 ) Why instituted . --This feast was instituted by God to commemorate the deliverance of the Israelites from Egyptian bondage and the sparing of their firstborn when the destroying angel smote the first-born of the Egyptians. The deliverance from Egypt was regarded as the starting-point of the Hebrew nation. The Israelites were then raised from the condition of bondmen under a foreign tyrant to that of a free people owing allegiance to no one but Jehovah. The prophet in a later age spoke of the event as a creation and a redemption of the nation. God declares himself to be "the Creator of Israel." The Exodus was thus looked upon as the birth of the nation; the Passover was its annual birthday feast. It was the yearly memorial of the dedication of the people to him who had saved their first-born from the destroyer, in order that they might be made holy to himself. First celebration of the Passover . --On the tenth day of the month, the head of each family was to select from the flock either a lamb or a kid, a male of the first year, without blemish. If his family was too small to eat the whole of the lamb, he was permitted to invite his nearest neighbor to join the party. On the fourteenth day of the month he was to kill his lamb, while the sun was setting. He was then to take blood in a basin and with a sprig of hyssop to sprinkle it on the two side-posts and the lintel of the door of the house. The lamb was then thoroughly roasted, whole. It was expressly forbidden that it should be boiled, or that a bone of it should be broken. Unleavened bread and bitter herbs were to be eaten with the flesh. No male who was uncircumcised was to join the company. Each one was to have his loins girt, to hold a staff in his hand, and to have shoes on his feet. He was to eat in haste, and it would seem that he was to stand during the meal. The number of the party was to be calculated as nearly as possible, so that all the flesh of the lamb might be eaten; but if any portion of it happened to remain, it was to be burned in the morning. No morsel of it was to be carried out of the house. The lambs were selected, on the fourteenth they were slain and the blood sprinkled, and in the following evening, after the fifteenth day of the had commenced the first paschal meal was eaten. At midnight the firstborn of the Egyptians were smitten. The king and his people were now urgent that the Israelites should start immediately, and readily bestowed on them supplies for the journey. In such haste did the Israelites depart, on that very day, ( Numbers 33:3 ) that they packed up their kneading troughs containing the dough prepared for the morrows provisions, which was not yet leavened. Observance of the Passover in later times . --As the original institution of the Passover in Egypt preceded the establishment of the priesthood and the regulation of the service of the tabernacle. It necessarily fell short in several particulars of the observance of the festival according to the fully-developed ceremonial law. The head of the family slew the lamb in his own house, not in the holy place; the blood was sprinkled on the doorway, not on the altar. But when the law was perfected, certain particulars were altered in order to assimilate the Passover to the accustomed order of religious service. In the twelfth and thirteenth chapters of Exodus there are not only distinct references to the observance of the festival in future ages (e.g.) ( Exodus 12:2 Exodus 12:14 Exodus 12:17 Exodus 12:24-27 Exodus 12:42 ; Exodus 13:2 Exodus 13:5 Exodus 13:8-10
