9992. 'And unleavened bread' means purification of what is celestial in the inmost part of a person. This is clear from the meaning of 'bread' as that which is celestial, dealt with in 2165, 2177, 3478, 9545; and from the meaning of what is 'unleavened' as what has been purified, dealt with below. The inmost part of a person is meant because what is celestial consists in the good of love, and the good of love is inmost. There are three degrees in a person that follow one another in order; and these three are called celestial, spiritual, and natural. The celestial degree is the good of love to the Lord, the spiritual is the good of charity towards the neighbour, and the natural descending from this is the good of faith, which, since it descends from the spiritual, is called spiritual-natural. The situation with a person resembles that in the heavens. The inmost heaven, also called the third heaven, is where the celestial degree is situated; the second or middle heaven is where the spiritual degree does so; and the first or lowest heaven is where the natural descending from the spiritual, or the spiritual-natural degree, does so. The reason why the situation with a person resembles that in the heavens is that a person in whom good is present is heaven in the smallest form it takes, see the places referred to in 9279. The celestial heaven or kingdom and the division of this too into three will be spoken of in what follows next where cakes and wafers made from fine wheat flour are the subject.

[2] 'Unleavened' means what has been purified because 'yeast' means falsity arising from evil, 2342, 7906, so that 'unleavened' or made without yeast means pure or free from that falsity. 'Yeast' means falsity arising from evil because such falsity defiles good, and truth as well, and also because it gives rise to conflict; for when that falsity gets near good, agitation occurs, and when it gets near truth, a collision takes place. All this explains why a minchah consisting of unleavened bread was included in burnt offerings and sacrifices. Therefore it was decreed that every minchah which they brought to Jehovah should be made without yeast, Leviticus 2:11; that they should not sacrifice the blood of a sacrifice with anything made with yeast, Exodus 23:18; and that during the feast of Passover they should not eat anything made with yeast, and that anyone eating it should be cut off from Israel, Exodus 12:15, 18-20. The reason why anyone who ate anything made with yeast during the feast of Passover should be cut off from Israel was that the feast of Passover was a sign of deliverance from damnation, and in particular of deliverance from falsities arising from evil, accomplished with those who allow themselves to be regenerated by the Lord, see 7093, 9286-9292. This also explains why it was called the feast of unleavened bread.

7906. 'No yeast shall be found in your houses' means no falsity whatever shall come near good. This is clear from the meaning of 'yeast' as falsity, dealt with below; and from the meaning of 'house' as good, dealt with in 3652, 3720, 4982, 7833-7835. The meaning of 'yeast' as falsity becomes clear from the places where yeast and anything made with yeast, and also where unleavened and anything made without yeast are mentioned, such as in Matthew,

Jesus said, Look out for and beware of the yeast of the Pharisees and Sadducees. Then the disciples understood that He had not said that they should beware of the yeast used in bread, but of the teaching of the Pharisees and Sadducees. Matthew 16:6, 11.

Here 'yeast' plainly stands for false teaching. Because 'yeast' meant falsity it was forbidden to sacrifice the blood of the sacrifice with anything made with yeast, Exodus 23:18; 34:25. For 'the blood of the sacrifice' meant holy truth, thus truth pure and free from all falsity, 4735, 6978, 7317, 7326, 7846, 7850. It was also laid down that the minchah offered on the altar should not be baked with yeast in it, Leviticus 6:15-17, and that cakes and wafers also should be made without yeast, Leviticus 7:11-13.

[2] To go further with what 'made with yeast' and 'not made with yeast' refer to, it should be recognized that the purification of truth from falsity cannot ever come about in a person without so called fermentation, that is, without the conflict of falsity with truth and of truth with falsity. But after the conflict has taken place and truth has triumphed, the falsity falls away like dregs and the truth emerges purified. It is like wine that becomes clear after fermentation as the dregs sink to the bottom. That fermentation or conflict takes place especially when a person's state undergoes a change, that is to say, when his actions begin to spring from the good of charity, and not as previously from the truth of faith. For a person's state is not yet made pure while his actions spring from the truth of faith, but they have been made pure when they spring from the good of charity, since they now spring from his will. Previously they sprang merely from his understanding.

[3] Spiritual conflicts or temptations are fermentations in the spiritual sense, for during them falsities wish to link themselves to truths, but the truths reject them, eventually sending them to the bottom so to speak and in that way becoming refined. This is the sense in which to understand what the Lord teaches about 'yeast' in Matthew,

The kingdom of heaven is like yeast, which a woman took and hid in three measures of flour, until the whole was fermented by it. Matthew 13:33.

'Flour' is truth from which good is derived. Also in Hosea,

They are all committing adultery, like an oven heated by a baker; the raiser ¹ ceases from kneading the dough until it has fermented. Hosea 7:4.

Since such conflicts, meant by 'fermentations', take place with a person in the state before he attains newness of life, as has been stated, it was also laid down that the new minchah, the bread of the wave-offering, that was to be brought at the feast of first fruits, should be baked with yeast; and that was to be the first fruits to Jehovah, Leviticus 23:16-17.
