9990. 'Take one young bull, a son of the herd' means purification of the natural or external man. This is clear from the meaning of 'a young bull' as the good of innocence and charity in the natural or external man, dealt with in 9391. And since the words 'a son of the herd' are used, the truth of that good is also meant, truth being meant by 'a son', and the natural level by 'the herd'. For the meaning of 'a son' as truth, see 489, 491, 533, 2623, 3373, 9807, and for that of 'the herd' as the natural level, 2566, 5913, 8937. The reason why purification of the natural or external man is meant here by 'a young bull, a son of the herd' is that the animal was offered in sacrifice, and sacrifices were signs of purification from evils and falsities, or expiation, in this instance purification from evils and falsities present in the natural or external man. But purification in the spiritual or internal man is meant by the burnt offering of a ram.

[2] To know what each kind of burnt offering or sacrifice represented one must first know that in a human being there is the external and the internal, and that in each there is that which belongs to truth and that which belongs to good. Therefore when a person is to be regenerated he must be regenerated as to the external and as to the internal, and in each as to truth and as to good. But before a person can be regenerated he must be purified from evils and from falsities, for these stand in the way. Purifications of the external man were represented by burnt offerings and sacrifices of oxen, young bulls, and he-goats, but purifications of the internal man by burnt offerings and sacrifices of rams, kids, and she-goats, and purification of the internal itself, or that which is inmost, by those of lambs. Consequently from the actual animals offered in sacrifice one may see what kind of purification or expiation was being represented.

[3] The reason for saying 'was being represented' is that burnt offerings and sacrifices did not purify or expiate a person, but merely served to represent purification or expiation. For is there anyone who fails to recognize that such offerings of animals do not take away any evil or falsity at all that is present with a person? - see the places in the Word quoted in 2180. The reason why those offerings did not take evil or falsity away, but merely represented such a removal of it, was that only a representative of the Church was established among the Israelite and Jewish nation, which served to join them to heaven, and through heaven to the Lord, see what has been shown on this subject in the places referred to in 9320 (end), 9380. But what was represented specifically by burnt offerings and sacrifices of young bulls, rams, and lambs, will be seen in what follows in the present chapter, since they are the subject there.

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.
