3373. 'And to your seed' means truth. This is clear from the meaning of 'seed' as truth, dealt with in 29, 255, 1025, 1447, 1610, 1940, 2848, 3310, and so truth from the Lord's Divine, which is 'your seed'. Those who understand the Word solely according to the sense of the letter can know no more than this, that 'seed' means descendants - here Isaac's descendants through Esau and Jacob, primarily through Jacob since the Word existed among that nation and so many of its historical descriptions have to do with them. But in the internal sense 'seed' is not used to mean any descendants from Isaac but all who are the Lord's 'sons', and so who are 'the sons of His kingdom', or what amounts to the same, those in whom good and truth which come from the Lord are present. And as these constitute 'the seed' it follows that good and truth themselves from the Lord are 'the seed', for these are what make people His 'sons'. This is also the reason why truths themselves which come from the Lord are called 'the sons of the kingdom' in Matthew,

He who sows the good seed is the Son of Man, the field is the world, the seed are the sons of the kingdom. Matthew 13:37-38.

And for this reason also 'sons' generally means truths, 489, 491, 533, 1147, 2623.

[2] Anyone who thinks rather more deeply or inwardly may recognize that the seed of Abraham, Isaac, and Jacob, mentioned so many times, and spoken of so many times as those who were to be blessed, and more so than all nations and peoples in all the world, cannot in the Divine Word mean the descendants of those three. For among all nations they least of all were moved by the good that flows from love to the Lord and from charity towards the neighbour. Nor indeed did any truth of faith exist with them. Who the Lord is, what His kingdom is, and so what heaven is and what the life after death, they did not know at all. They did not know these things because for one thing they did not wish to know and for another because if they had come to know about them they would have denied them completely in their hearts and so would have profaned interior goods and truths, as they did exterior by becoming on so many occasions open idolaters. This is the reason why any interior truths are rarely visible in the literal sense of the Old Testament Word. Because the nature of those people was such, the Lord therefore said about them, quoting Isaiah,

He has blinded their eyes and hardened their heart, lest they see with their eyes and understand with their heart, and are converted and I heal them. John 12:40.

What He said about them when they declared they were 'the seed of Abraham',

They said, We are the seed of Abraham. Our father is Abraham. Jesus said to them, If you were Abraham's sons, you would do the works of Abraham. You are from your father the devil, and the desires of your father you will to do. John 8:33, 39, 44.

Here also 'Abraham' is used to mean the Lord, as in every other instance in the Word. The Lord explicitly states that they were not His seed or sons but came from the devil. From this it is quite evident that 'the seed of Abraham, Isaac, and Jacob' in both the historical part and the prophetical part of the Word is in no way used to mean such descendants, for the Word is Divine in every detail Instead it means all who constitute 'the Lord's seed', that is, those with whom the good and truth of faith in Him are present. The fact that heavenly seed, that is, all good and truth, comes from the Lord alone, see 1438, 1614, 2016, 2803, 2882, 2883, 2891, 2892, 2904, 3195.

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.
