1997. I will multiply thee very exceedingly. That this signifies the fruitfulness to infinity of the affection of truth, may be seen from the signification of “to be multiplied,” as being predicated of truth (explained, n. 43, 55, 913, 983); and as the Lord is treated of, it signifies the fruitfulness to infinity of the truth that is from good (as before, n. 1940). There are two affections, namely, the affection of good, and the affection of truth. The affection of good is to do what is good from the love of good, and the affection of truth is to do what is good from the love of truth. At the first view these two affections appear to be the same; but in reality they are distinct from each other both as to essence and as to origin. The affection of good, or doing what is good from the love of good, is properly of the will; but the affection of truth, or doing what is good from the love of truth, is properly of the understanding. Thus these two affections are distinct from each other in the same way as are the will and the understanding. The affection of good is from celestial love, but the affection of truth is from spiritual love.

[2] The affection of good can be predicated solely of the celestial man, but the affection of truth, of the spiritual man. What the celestial or the celestial man is, and what the spiritual or the spiritual man, has been sufficiently shown in Part First. The Most Ancient Church, which existed before the flood, was in the affection of good; but the Ancient Church, which existed after the flood, was in the affection of truth; for the former was a celestial church, but the latter a spiritual church. All the angels in the heavens are distinguished into the celestial and the spiritual. The celestial are they who are in the affection of good, the spiritual are they who are in the affection of truth; to the former the Lord appears as a sun, but to the latter as a moon (n. 1529-1531, 1838). This latter affection, of truth, the Lord united to the affection of good, which is to do what is good from the love of good, when He united the Human Essence to the Divine Essence. Hence by “multiplying very exceedingly,” is signified the fruitfulness to infinity of the truth that is from good.

983. That “be fruitful” signifies the good of charity, and “multiply” the truths of faith, which were now about to be increased, is evident from the signification of these two expressions in the Word, where “to be fruitful” or to produce fruit, is constantly predicated of charity, and “to multiply” of faith, as was shown above, n. 43, 55, and in further confirmation of which we may adduce the following passages from the Word:

Turn, O backsliding sons; I will give you shepherds according to Mine heart, and they shall feed you with knowledge and intelligence and it shall be that ye shall be multiplied and made fruitful in the earth (Jeremiah 3:14-16),

where “to be multiplied” manifestly denotes growth in knowledge and intelligence, that is, in faith, and “to be made fruitful” denotes the goods of charity; for it there treats of the implantation of the church, in which faith or “multiplication” comes first.

Again:

I will gather the remnant of My flock out of all lands whither I have driven them, and will bring them again to their folds, and they shall be fruitful and multiplied (Jeremiah 23:3),

speaking of a church already planted, consequently to be “made fruitful” as to the goods of charity and to be “multiplied” as to the truths of faith.

So in Moses:

Moreover I will look to you, and make you to be fruitful, and I will make you to be multiplied, and establish My covenant with you (Leviticus 26:9), speaking in the internal sense of the celestial church, wherefore “to be fruitful” is predicated of the goods of love and charity, and “to be multiplied” of the goods and truths of faith.

In Zechariah:

I will redeem them, and they shall be multiplied as they have been multiplied (Zechariah 10:8); that “to be multiplied” is here predicated of the truths of faith, is evident from their being to “be redeemed.”

In Jeremiah:

The city shall be builded upon her own heap, and out of them shall proceed confession, and the voice of them that make merry, and I will cause them to be multiplied, and they shall not be diminished; their sons also shall be as aforetime (Jeremiah 30:18-20),speaking of the affections of truth, and of the truths of faith; the former being denoted by “confession, and the voice of them that make merry” and the latter by “being multiplied;” “sons” also here denote truths.
