7906. Shall no leaven be found in your houses. That this signifies that nothing whatever of falsity shall come near good, is evident from the signification of “leaven,” as being falsity (of which in what follows); and from the signification of “house,” as being good (see n. 3652, 3720, 4982, 7833-7835). That “leaven” denotes falsity can be seen from those passages where “leaven” and “leavened” and also “unleavened” are mentioned, as in Matthew:

Jesus said unto them, See ye and beware of the leaven of the Pharisees and of the Sadducees. Afterward the disciples understood that He had not said that they should beware of the leaven of bread, but of the doctrine of the Pharisees and Sadducees (Matthew 16:6, 12); where “leaven” manifestly means false doctrine. As “leaven” signified falsity, it was forbidden to sacrifice upon what was leavened the blood of the sacrifice (Exodus 23:18; 34:25); for by the “blood of the sacrifice” was signified holy truth, thus truth pure from all falsity (n. 4735, 6978, 7317, 7326, 7846, 7850). It was also ordained that the meat-offering which was to be offered upon the altar was not to be baked leavened (Leviticus 6:17); and that the cakes and wafers also should be unleavened (Leviticus 7:11-13).

[2] As further regards what is leavened and what is unleavened, be it known that the purification of truth from falsity with man cannot possibly exist without fermentation so called, that is, without the combat of falsity with truth and of truth with falsity; but after combat has existed, and truth has conquered, then falsity falls down like dregs, and the truth comes forth purified, like wine which grows clear after fermentation, the dregs falling to the bottom. This fermentation or combat exists chiefly when the state with man is being changed, that is, when he begins to act from the good that is of charity, and not as before from the truth that is of faith; for the state has not as yet been purified when the man acts from the truth of faith, but it has been purified when he acts from the good which is of charity; for then he acts from the will; previously only from the understanding.

[3] Spiritual combats or temptations are fermentations in the spiritual sense; for then falsities are desirous to conjoin themselves with truths; but truths reject them, and finally cast them down as it were to the bottom, consequently they purify. In this sense is to be understood what the Lord teaches about leaven in Matthew:

The kingdom of the heavens is like unto leaven, which a woman took, and hid in three measures of meal, until the whole was leavened (Matthew 13:33);

“meal” denotes the truth from which is good. Also in Hosea:

They are all adulterers, as an oven heated by the baker; the stirrer ceaseth from the kneading of the dough until it be leavened (Hos. 7:4).

Because, as before said, such combats as are signified by fermentations arise with man in the state previous to newness of life; therefore it was also ordained that when the new meat-offering on the feast of the first-fruits was offered, the bread of waving was to be baked leavened, and was to be the first-fruits to Jehovah (Leviticus 23:16-17).

7850. And they shall eat the flesh. That this signifies the enjoyment of good, is evident from the signification of “to eat,” as being enjoyment (of which just above, n. 7849); and from the signification of “flesh,” as being what is man’s own vivified by the Divine Human of the Lord, thus all celestial and spiritual good with man (see n. 3813, 6968). That “flesh” has this signification was well known among the ancients, and yet at this day it is so unknown that everyone would be surprised on being told that “flesh” has such a signification. If it is said that it is a spiritual correspondent, this is not understood. If it is said that it is a significative, this is indeed understood, but in another sense than that in which it is a significative correspondent, namely, as something quite separate; when yet a spiritual or significative correspondent is conjoined with that to which it corresponds as is a man’s sight with his eye; his hearing with his ear; his thought, which is spiritual, with the form of his interiors, and through this form with the little organs of speech; or as the will, which also is spiritual, is conjoined with the muscular fibers by which action is produced. Such is the case with every spiritual correspondent or significative relatively to its natural, with which there is correspondence.

[2] Who cannot see that by “flesh” is not meant flesh, nor by “blood” blood, by the Lord in John:

Verily, verily, I say to you, Except ye eat the flesh of the Son of man and drink His blood, ye have no life in you; he that eateth My flesh and drinketh My blood hath eternal life, and I will raise him up at the last day; for My flesh is meat indeed, and My blood is drink indeed (John 6:53-55).

That by “flesh” is meant the Divine good of the Divine love of the Lord, which is from His Divine Human, and by “blood” the Divine truth proceeding from His Divine good, and also the man’s reciprocity, is at this day known to few, and they who can know, will not. The reason why they are unwilling to know is that they are in no affection of truth for the sake of truth, but only for the sake of worldly reasons, and also because natural men desire to apprehend all things naturally.

[3] These things have been said in order that it may be known what is signified by “eating flesh” at the paschal supper, consequently what at the Holy Supper, which was then instituted. (Concerning the bread and the wine which in the Holy Supper signify the same as the flesh and the blood, see n. 2165, 2177, 2187, 3464, 3478, 3735, 3813, 4211, 4217, 4735, 4976, 5915) That in the spiritual sense of the Word “flesh” does not mean flesh, besides being manifest from other passages, is also very evident from this in Revelation:

Come and be ye gathered together unto the supper of the great God; that ye may eat the flesh of captains, and the flesh of mighty men, and the flesh of horses and of them that sit thereon, and the flesh of all both free and bond, both small and great (Revelation 19:17-18); where by “flesh” are signified goods of various kinds.
