3186. 'Our sister, may you become thousands of myriads' means infinite fruitfulness of the affection for truth. This is clear from the meaning of 'sister', who is Rebekah, as the affection for truth, dealt with in 3077, 3179, 3182, and from the meaning of 'may you become thousands of myriads' as infinite fruitfulness. Here 'thousands of myriads' means that which is infinite because the subject is the Lord in whom every single thing is infinite. With man the situation is that goods are not fruitful with him and truths are not multiplied until truth and good have become joined together in his rational, that is, until he has been regenerated. For at that point fruits or offspring from the rightful or heavenly marriage, which is the marriage of good and truth, come into being. Prior to this the goods which he puts into practice, it is true, look like goods, and truths like truths; but these are not genuine, since the soul which is good that has innocence from the Lord within it is not present in them. Thus they do not stir any affection in him nor do they bring him happiness. The affection that accompanies love and charity, together with happiness, is the soul, and that affection is imparted by the Lord to a person when being regenerated.

[2] 'A thousand' meaning much, also that which is infinite - see 2575 - 'a myriad' means that which is even more, and 'thousands of myriads' that which is even more again, as also elsewhere. In Moses,

When the Ark came to rest he said, Return, O Jehovah, to the myriads of the thousands of Israel. Numbers 10:36.

Here also 'the myriads of thousands' means that which is infinite because it has reference to the Lord, who is Jehovah here. In the same author,

Jehovah dawned from Seir upon them, He shone from Mount Paran, and came out of myriads of holiness. Deuteronomy 33:2.

'Myriads' again stands for that which is infinite. In David,

The chariots of God are myriads of thousands of peacemakers. Psalms 68:17.

'The chariots of God' stands for things which belong to the Word and to doctrine drawn from it, 'myriads of thousands' for infinite things present there. In John,

I looked, and I heard the voice of many angels around the throne, numbering myriads of myriads, and thousands of thousands. Revelation 5:11.

This stands for the fact that they were countless.

1940. That 'I will multiply your seed greatly' means the fruitfulness of the rational man when it submits itself to the controlling power of the interior man allied to good is clear from the meaning of 'seed' as love and faith, dealt with already in 1025, 1447, 1610. Here however 'multiplying seed' means the fruitfulness within the rational of the celestial things of love when the rational has submitted itself to truth that is interior or Divine. 'Being multiplied' has reference to truths but 'being fruitful' to goods, as is clear from what has been stated and shown already in 43, 55, 913, 983. But as the subject is the Lord, 'being multiplied' means being fruitful for the reason that all truth within His Rational became good and so Divine; and this is what is being referred to here. In man's case it is different - his rational is formed by the Lord from truth or the affection for truth. This affection is in him good from which he acts.

[2] As regards multiplication and fruitfulness within man's rational, this cannot be understood unless one knows about influx, regarding which the following may be said of it in general: Within everybody, as stated already, there is the internal man, the rational man, which is in the middle, and the external man. The internal man is the inmost part of him by virtue of which he is a human being and which makes him distinct and separate from animals, which do not possess that inmost part. The internal man is so to speak the door or entrance for the Lord, that is, for celestial and spiritual things that are the Lord's, to come into a person. What goes on there the individual cannot comprehend since it is entirely above his rational from which he thinks. To this inmost or internal man the rational which appears as the person's own is subordinate. Into this rational by way of that internal man flow heavenly things of love and faith from the Lord; and by way of this rational they flow on into the facts that belong to the external man. But how these things flowing in are received depends on the individual person's state.

[3] Unless the rational is submissive to goods and truths that are the Lord's this rational either stifles, or rejects, or perverts the things that flow in, the more so when they flow into facts in the memory that are derived from sensory evidence. These things when so received are meant by the seed that falls either on the pathway, or over stony ground, or among thorns, as the Lord teaches in Matthew 13:3-7; Mark 4:3-7; Luke 8:5-7. But when the rational is submissive and believes the Lord, that is, His Word, the rational is like the ground or good soil into which the seed falls and bears much fruit.
