7887. Even on the first day ye shall cause leaven to cease from your houses. That this signifies that no falsity whatever must be in the good, is evident from the signification of "the first day," as being the beginning of that state (that "day" denotes state, see just above, n. 7881); from the signification of "leaven," as being falsity (of which below); and from the signification of "house," as being good (see n. 2233, 2234, 2559, 3652, 3720, 7833-7835, 7848). From this it is plain that by "even on the first day ye shall cause leaven to cease from your houses," is signified that from the very beginning of that state there shall be no falsity in the good. With respect to good the case is this. Goods are infinite in variety, and they have their quality from truths; consequently the good becomes such as are the truths which enter. The truths which enter are seldom genuine, but are appearances of truth, and also are falsities, but still not opposite to truths. Nevertheless when these falsities flow into good, which is the case when the man lives according to them, from ignorance, in which ignorance there is innocence, and when the end is to do what is good, then they are regarded by the Lord and in heaven, not as falsities, but as semblances of truth, and according to the quality of the innocence are accepted as truths; from this, good receives its quality. From all this it can be seen what is meant by its being said that there must be nothing false in the good.
