6647. And the sons of Israel were fruitful, and were productive. That this signifies that the truths of the church increased as to good, is evident from the representation of the sons of Israel, as being spiritual truths (see n. 5414, 5879), and the church (n. 6637); from the signification of "to be fruitful," as being to increase as to good (n. 43, 55, 913, 983, 2846, 2847, 3146); and from the signification of "to be productive," as being further derivation; for when the church has been set up anew with man, then good continually increases and is derived, both in the internal, and also toward and in the external. That with those of the spiritual church good increases by means of truths, has already been often shown; for the man of the spiritual church has not perception, as the man of the celestial church has, and therefore he does not know what the good of the church, or spiritual good, is, except by means of truths. Therefore when the man of the spiritual church is being regenerated, truths are stirred up by the Lord through the angels who are with him, and thereupon he is led into good. But when the man has been regenerated, then both truth and good together are stirred up, and in this way he is led. With the man of the spiritual church however, such as is the truth, such is the good, and hence such is the conscience, which is to him as perception, according to which he lives.
