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).

3142. For I have swept the house. That this signifies that all things were prepared, and full of goods, is evident from the signification of “sweeping,” as being to prepare and to be filled (of which we shall speak presently); and from the signification of a “house” as being good (concerning which above, n. 2233, 2234, 2559; and that man himself, from the good which is in him, is called a house, n. 3128). The reason “to sweep” signifies to prepare and to be filled, is that nothing else is required of man than to sweep the house; that is, to reject the cupidities of evil and the derivative persuasions of falsity; for he is then filled with goods, because good is continually flowing in from the Lord-but into “the house,” that is, into the man who is purified from such things as impede the influx, that is, which reflect, or pervert, or suffocate the inflowing good. Hence it was common with the ancients to speak of sweeping or cleaning the house, and of sweeping and preparing the way; and by sweeping the house was meant to purify one’s self from evils, and thereby to prepare one’s self for goods to enter; but by sweeping the way was meant to prepare one’s self so that truths might be received (for by a “house” was signified good, n. 3128; and by a “way,” truth, n. 627, 2333).

[2] As in Isaiah:

The voice of one crying in the wilderness, Sweep [prepare] ye the way of Jehovah; make straight in the desert a highway for our God (Isaiah 40:3).

In the same:

Cast up, cast up, sweep [prepare] the way, take away the stumbling-block out of the way of My people (Isaiah 57:14).

Again:

Go through, go through the gates, sweep [prepare] the way of the people; cast up, cast up the highway, gather out the stones (Isaiah 62:10).

In Malachi:

Behold I send Mine angel, and He shall sweep [prepare] the way before Me; and the Lord, whom ye seek, shall suddenly come to his temple (Malachi 3:1).

In these passages, to “sweep the way” signifies to make themselves ready and prepare to receive truth. The subject treated of therein is the advent of the Lord, for which they were to prepare themselves for receiving the truth of faith, and thereby the good of charity, and by this eternal salvation.

[3] In David:

Thou hast brought a vine out of Egypt, Thou didst drive out the nations and plantedst it; Thou didst sweep before it, and didst cause its root to be rooted, and it filled the land (Psalms 80:8-9); where in the supreme sense the Lord is treated of; the “vine out of Egypt” is truth from memory-knowledges; “driving out the nations” is purifying from evils; “sweeping before it,” is making ready so that goods may fill. In the opposite sense “to sweep the house” is said also of the man who deprives himself of all goods and truths, and thus is filled with evils and falsities; as in Luke:

The unclean spirit, finding no rest, says, I will return into my house whence I came out; and when he is come he findeth it swept and garnished; then goeth he and taketh to him seven other spirits worse than himself, and they enter in and dwell there (Luke 11:24-26; Matthew 12:43-45).
