=Suggestions to the teacher.= The association of the Exodus with the observance of Passover is the obvious method of establishing a contact between the subject to be taught in this lesson and the Jewish child of today. Nevertheless, it is better not to employ the observances of the Passover as the technical "point of contact" with which to introduce the original presentation of the lesson, as that would delay too long the actual narration, but to use them to introduce the discussion of the topic by the class after the teacher has told his story. To introduce the narrative itself a reference to previous lessons is sufficient, as the last few lessons have all anticipated the events told in these chapters. This the teacher can best do by a few introductory questions, as, for instance; "Why did God send the plagues of which we learned in our last lesson against Egypt?" (Draw out the answer that it was not merely to punish the Egyptians but to compel Pharaoh to free the Israelites.) When, after the ninth plague, Moses refused Pharaoh's offer to let the Israelites go on condition that they left their cattle and possessions behind, what did Pharaoh say? How did Moses answer? The teacher then continues: "When Pharaoh had driven Moses and Aaron from him and told them never to come before him again or he would have them put to death, it was plain that there was no use arguing with him any more. God had given him many chances to change his attitude and let the Israelites go in peace, to serve Him in the wilderness, but Pharaoh would not listen and now God decided to send one more plague upon Egypt, so terrible that Pharaoh would be forced to let the Israelites go." In telling of the sacrifice of the Paschal lamb and the sprinkling of the blood on the doorposts, guard against leaving the child with the notion that God really required a sign in order to distinguish the Hebrew from the Egyptian house. This can be done by explaining that God wanted to test the faith of the Israelites in the expected exodus by their readiness to make these preparations. The sprinkling of the blood on the doorposts was to be a sign that the inmates of the house wanted it to be considered a Hebrew house, but if they were willing to remain in Egypt and would not trust God to lead them out, they would naturally not make these preparations, and would deserve to be treated like all the other Egyptians. Call attention to the change in the attitude of the people to Moses and Aaron since God had shown His power in the plagues, for at first they would not listen to them "for impatience of spirit and for cruel bondage", and now they obeyed the minutest prescriptions of Moses in anticipation of the exodus.
