The Passover feast was therefore nothing new. The rite connected with it and the ideas associated with the rite must have long been familiar to the Israelites. What was new was the adaptation of the rite to the new covenant that Yahveh was about to enter into with His people. It became ‘the Lord’s Passover,’ commemorating the deliverance from Egypt when Yahveh smote the Egyptian firstborn, but ‘passed over the houses of the children of Israel.’ Like the old springtide feast of unleavened bread, it was given a new signification, and made a memorial of the first event in the national life of Israel. A similar significance was given to a change that was made in the calendar. The Hebrew year had begun in the autumn with the month of September; but side by side with this West-Semitic calendar there had also been in use in Palestine another calendar, that of Babylonia, according to which the year began with Nisan or March. It was this Babylonian calendar which was now introduced for ritual purposes. While the civil year still began in the autumn, it was ordained that the sacred year should begin in the spring. The sacred year was determined by the annual festivals, and the first of the festivals was henceforth to be the Passover. The beginning of the new year was henceforth fixed by the Passover moon. It was at midnight that the angel of death passed over the land of Egypt. The plague spared neither rich nor poor. The firstborn of Pharaoh died like the firstborn of the captive in prison. Vain attempts have been made to discover which among the sons of Meneptah this may have been. But Meneptah lived many years after the overthrow of the Libyans, and consequently after the Exodus of the Israelites, and it may not have been till late in his reign that his successor, Seti II., became crown-prince. More than one elder brother may have died meanwhile. Moreover, none but the son of a princess of the royal solar race could sit on the throne of the Pharaohs. The reigning king might have elder sons born to him by foreign princesses, but his successor could not be chosen from among them. He only who could trace his descent to the Sun-god, who was, in short, a direct descendant of the Pharaohs, had any right to the throne. Amid the terrors of the plague, and under cover of the darkness, the Israelites and their companions, the ‘mixed multitude,’ departed from the land of Goshen. They took with them their flocks and herds; they took also such precious plunder as they could easily carry away from the houses of their terrified masters. They ‘borrowed,’ according to the euphemistic expression of the chronicler, ‘jewels of silver and jewels of gold, and raiment,’ ‘and they spoiled the Egyptians.’ It was little wonder that the Pharaoh subsequently determined to pursue the retreating hordes.
