"for there was no house where no one had died": R. Nathan said: Now were there not houses without first-born?—(The resolution:) If one lost a first-born, he would make an image of him and place it in his house (thinking thereby to preserve him). And on that day the image would disintegrate and be scattered as powder. And that day was as grievous to them as the day of his burial (Thus: "there was no house where no one had died.") And, what is more, the Egyptians would bury them in their houses, and dogs would come and gnaw their way in and would remove the first-born from their crypts and mutilate the corpses. And that day was as grievous to them as the day of burial.
