1940. In multiplying I will multiply thy seed. That this signifies the fruitfulness of the rational man when it submits itself to the sovereign control of the interior man when this is adjoined to good, is evident from the signification of “seed,” as being love and faith (spoken of before, n. 1025, 1447, 1610), but in the present case by “multiplying seed” is signified the fruitfulness of the celestial things of love in the rational, when the rational has submitted itself to interior or Divine truth. “Multiplication” is predicated of truth, and “fruitfulness” of good, as may be seen from what has already been said and shown (n. 43, 55, 913, 983). But as the Lord is here treated of, “multiplying” signifies becoming fruitful, because all the truth in His rational was made good, and thereby Divine, as is here declared concerning Him. It is otherwise in man, whose rational is formed by the Lord from truth or the affection of truth. This affection is his good, from which he acts.

[2] How the case is with man’s rational in regard to multiplication and fruitfulness cannot be understood unless we know how the case is with influx, of which it may be said in a general way that in everyone there is an internal man, a rational man which is intermediate, and an external man, as before said. It is the internal man that is his inmost from which he is man, and by which he is distinguished from brute animals, which have not such an inmost; and it is as it were the door or entrance for the Lord, that is, for what is celestial and spiritual from the Lord, into man. What is going on there cannot be comprehended by the man, because it is above all his rational, from which he thinks. That rational which appears as man’s own is subject to this inmost, or to this internal man, and into this rational through the internal man there inflow from the Lord the heavenly things of love and of faith, and through this rational they inflow into the memory-knowledges that are in the external man; but the things that inflow are received in accordance with the state of each person.

[3] Now unless the rational submits itself to the Lord’s goods and truths, it either suffocates, or rejects, or perverts the things that flow in; and this is still more the case when they flow into the sensuous knowledges of the memory. This is what is meant by seed falling on a highway, or upon a rocky place, or among thorns, as the Lord teaches (Matthew 13:3-7; Mark 4:3-7; Luke 8:5-7). But when the rational submits itself and believes the Lord, that is, His Word, the rational is then like good ground or earth, into which the seed falls and bears much fruit.

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.
