8020. It is plainly evident from the statutes and laws regarding the eating of the Passover lamb which appear in this chapter that in every detail they contain and conceal heavenly arcana, and that without knowledge gained from the internal sense one can see no more in them than the outward form of a religious custom, and nothing heavenly, let alone Divine. Without that knowledge one does not know the reason for any of the following: Why the Passover animal was to be a lamb or a kid; why the animal was to be a male, and 'the son of a year'; why it was to be slaughtered on the fourteenth day of the month; why the blood from it was to be sprinkled on the doorposts and lintel; why it was to be eaten roasted with fire, together with unleavened bread on bitter herbs, and not any of it raw or boiled in water; why its head was to be roasted over its legs and over its middle; why none of it was to be left till morning, and why what remained was to be burned with fire; why they were to eat unleavened bread for seven days, and why anyone eating anything made with yeast was to be cut off; why the foreigner, the stranger, and the hired servant could not eat it, but a man's slave, a purchase paid for with silver, and a sojourner, could eat it if they were circumcised; why it was to be eaten in one house and none of the flesh was to be brought outside; and why no bone of it was to be broken. What these and very many other regulations hold within them, and why they were commanded, would remain completely unknown unless the laws of order in the spiritual world to which they correspond were known, unless knowledge were acquired from the internal sense of what each regulation means in that world, that is, in heaven, and in particular unless the belief existed that all of them contain a spiritual level of meaning. Unless every single one contained this spiritual level of meaning the angels present with a person would understand little or scarcely anything of the Word when read by the person; for all the things which have been described in the Word in a natural way are understood by the angels on a spiritual level of meaning.
