4676. 'For he was the son of his old age' means its own life within it. This is clear from the meaning of 'old age' as the casting aside of the previous state and the assumption of the new one, and also as newness of life, dealt with in 3492, 4620. For in the internal sense 'old age' does not mean old age, for the reason that the internal man, or man's spirit, does not know what old age is; but as the body or the external man grows old, so he passes into newness of life. As he ages man's spirit is made more perfect, at the same time as his physical powers diminish. This is truer still in the next life, for those in heaven are constantly being led by the Lord into a more perfect life, and at length into the bloom of youth, including those people who have died at a ripe old age. From these considerations it may be seen that in the internal sense 'old age' means life. What is meant by the expression 'its own life within it' has been explained above in 4667.

[2] Just above it was said that man's spirit or the internal man does not know what old age is, and yet before that it was said that it is in this spirit within the body where thinking takes place, and also that life flows from the spirit to the body. The reason why that thought belonging to the spirit cannot be communicated to the body, enabling the person to know that he lives after death is that as long as his spirit remains within the body he cannot do other than think from the assumptions which his natural man has been adopting. And if he has made the assumption and is convinced that only the body is living and that when this dies the whole human being does so, the influx of that spiritual reality is not received. Evidence of the existence of that influx may nevertheless be seen in the fact that most people are concerned about their own burial and the tributes paid to them after death, some about their reputation then, on account of which they also erect splendid monuments to themselves so that the memory of them may not be lost. These are the kinds of things into which the influx from heaven regarding the continuance of life is channeled by those who otherwise have no belief in that life. Without that influx they would treat with utter disdain all remembrance of themselves after they have died.

2089. 'Twelve princes will he beget' means the first and foremost commandments [of faith] inhering in charity. This is clear from the meaning of 'twelve' as all things belonging to faith, and from the meaning of 'princes' as first and foremost features. King and princes are mentioned in various places in the Word, but in the internal sense they nowhere mean king or princes but the first and foremost features of the subject under discussion. That 'kings' means truths taken as a whole has been shown already in 2015, and that 'princes' means the first and foremost aspects of truth, which are commandments, in 1482. For this reason angels, especially spiritual angels, are called principalities, because they are governed by truths. Princes have reference to truths which go with charity because, as stated above in 2088, spiritual people receive charity from the Lord through truths which to them look like truths, and through charity they receive conscience.

[2] Up to now the world has not known that 'twelve' means all things of faith. Yet every time the number twelve occurs in the Word, in historical or in prophetical sections, it has no other meaning. The twelve sons of Jacob, and therefore the twelve tribes named after them, have no other meaning. And the same applies to the Lord's twelve disciples. Each one of Jacob's sons and each of the disciples represented some essential and primary aspect of faith. What each son of Jacob represented, and therefore what each tribe of Israel represented, will in the Lord's Divine mercy be discussed later on at Genesis 29, 30, where the sons of Jacob are the subject.
