For that night, at midnight, the destroying angel would pass through the land of Egypt, to kill all the first-born of the Egyptians; and there would not be one house where there was not one dead. Perhaps you think to yourselves, children, "But would the first-born of the Israelites die too? How would the destroying angel know which were Egyptians, and which were the Children of Israel?" Ah! God had foreseen how to prevent that! He had not let plagues touch the houses of His own people! He told Moses that all who wished to be safe on that dreadful night, must take a lamb, and when they had killed it, they must put its blood in a basin, and sprinkle the blood on their houses. God told them to take a bunch of hyssop, and to sprinkle the top of the doorway and the side posts with blood; and He promised that when He saw the blood He would pass over that house, and not allow the destroying angel to enter. That was why it was called The Lord's Passover. And when God saw the blood of the Lamb, He looked forward to the time when His own dear Son would be the Lamb of God which taketh away the sin of the world. Do you not think, children, that those Israelites made sure that the blood was sprinkled on their house? Can you not Picture them running outside to look before they shut themselves inside the door? And can you not almost hear them saying, "Yes, there is the blood of the Lamb! Now we are safe!" And so hurry inside again, and stay there until the morning, as they were commanded. And does not this question come home to your heart and mine to-day? Is the blood of the Lamb of God sprinkled on my heart? Am I safe from the punishment of my sins because Jesus died for me? If so, children, we may rest secure, and go out rejoicing on our journey towards the Promised Land in heaven. * * * * * * * God told them also to take the flesh of the lamb and to roast it at the fire, and all who were in the house were to eat the Passover Supper. It was a night to be remembered for ever, when the Lord delivered His people out of Egypt! And we, too, may say— "Christ our Passover is sacrificed for us, therefore let us keep the feast!" XLIV. Bread from Heaven So the Israelites left the Red Sea behind, and they went three days' journey into the wilderness, and found no water for them to drink. At length they came to a place called Marah, where to their joy they found some water. But when they came to taste it, the water was so bitter that they could not drink it. Then the people were very very angry with Moses, and blamed him very much. So Moses cried to the Lord; and the Lord shewed him a tree, which when he had cast into the waters they were made sweet and nice, and the people could drink. Soon after this the great company had eaten up all the bread they had brought out of Egypt, and there were no shops to buy anything at, nor any corn growing in the wilderness.
