Inasmuch as there are so many allusions to the ten plagues in Jewish and general literature, the child should be taught to remember them in their proper order. This can be done best by naming each plague in a single word or brief phrase, as in the Passover Haggadah, and writing them on the blackboard thus: 1. Blood. 6. Boils. 2. Frogs. 7. Hail. 3. Gnats. 8. Locusts. 4. Flies. 9. Darkness. 5. Pestilence among cattle. 10. Death of first-born. CHAPTER VI THE EXODUS Exodus 11.1 to 13.16 =Interpretation.= These chapters relate the climax toward which the narrative from the birth of Moses until this point has been leading, the exodus from Egypt. They also contain the laws associated with the commemoration of this event. The narrative begins by telling of God's promise that the next plague would be the last, and His command to the people to prepare for the exodus. Before they were permitted to leave, some expression of their faith in God's deliverance and their readiness to follow His guidance was required; therefore, we have the command to take a lamb on the tenth day of the month, which was to begin their new era, and sacrifice it on the 14th, and eat the flesh of it in family groups on that night, together with bitter herbs and unleavened bread, which thereafter were to serve as symbols of the bondage and of the liberation from it. The blood of this sacrifice, they were to sprinkle on the doorposts of their houses in order to testify by this ritual to their desire to be included in the "Army of the Lord" that was to depart on the morrow, and all who did not testify thus to their adherence to Israel's cause were to meet with the same fate as the Egyptians with whom they had chosen to identify themselves. The Israelites were to eat the lamb while standing with their loins girt and staves in their hands, in readiness for the signal to depart. The rabbis call attention to the fact that the sacrifice of the Paschal lamb in Egypt by the Israelites was a very bold expression of their faith, inasmuch as the sheep was among the sacred animals of Egypt. When Pharaoh suggests to Moses that the Israelites could sacrifice to their God in Egypt, he replies, "Lo, if we sacrifice the abomination of the Egyptians before their eyes, will they not stone us?" (Exodus 8. 22.) But by this time Pharaoh and Egypt had been so humiliated by the plagues which did not even spare their sacred river Nile, that the Egyptians feared to attack the Israelites, while the children of Israel had recovered their lost confidence in Moses, and in the God in whose name he spoke to them.
