4670. 'A son of seventeen years' means His state. This is clear from the ages measured in years of people mentioned in the Word - spiritual realities and states are meant by them, as these are by all other numbers. For all numbers in the Word have spiritual realities and states as their meaning, see 575, 647, 648, 1988, 2075, 2252, 3252, 4264, 4495, as also do years, 487, 488, 493, 893.

[2] It does indeed seem as though numbers of years, or ages measured in years, mean nothing else than numbers of years. This is because these numbers more than any others have so to speak a more specific historical application. But these numbers too include spiritual realities and states within them, as is clear from the applications given at Genesis 5 and from what has been stated at Genesis 17:1 and Genesis 25:7 about Abraham's age and at Genesis 35:28 about Isaac's. The same is clear in addition from the fact that no historical detail exists anywhere in the Word which does not include within it something heavenly into which it is also changed when it passes from the thought of the reader to the angels present with him, and through those angels into heaven where the spiritual sense rises up out of every historical reference in the Word.

[3] But what is meant by Joseph's being seventeen years old may be seen from the meaning which this number has elsewhere, namely a beginning, in this case the beginning of the representation through Joseph. As to its meaning a beginning and that which is new, see 755, 853. What is more, this number includes within itself in a general way, and so to speak potentially, all the things that are represented by 'Joseph' - 'seven' meaning that which is holy and 'ten' remnants. For 'seven' when used in the Word adds holiness to any meaning, see 881, while 'ten' means remnants, 576, 1906, 2284. The remnants present in the Lord were Divine and His own, and by means of them He united the Human Essence to the Divine Essence, 1906.

3167. 'And to [her] mother' means to natural truth also, that is to say, spiritual things passed from the rational to it, even as they passed to natural good, dealt with just above. This is clear from the meaning of 'a mother' as the Church, which by virtue of truth is called 'a mother', dealt with in 289, 2717. So that people may know how spiritual things pass to natural good and to natural truth as a result of truth being introduced into good in the rational, a brief description must be given here. Everyone has an internal and an external, his internal being called the internal man, and his external the external man. But few know what the internal man is and what the external. The internal man is one and the same as the spiritual man, and the external man one and the same as the natural man. The spiritual man depends for understanding and wisdom on things that belong to the light of heaven, whereas the natural depends for its understanding and wisdom on things that belong to the light of the world. Regarding those two kinds of light, see 3138. For in heaven none but spiritual things exist, whereas in the world none but natural exist. The human being was created in such a way that in him spiritual things and natural things, that is, his spiritual man and his natural man, should accord with each other or make one. But in that case the spiritual man ought to have control over the things in the natural, and the natural man ought to obey, like a servant his master.

[2] Through the Fall however the natural man started to raise itself above the spiritual man and so turn Divine order itself upside down. As a consequence the natural man separated itself from the spiritual, and spiritual things could not reach it any longer except so to speak through chinks to provide the ability to think and speak. But so that spiritual things might flow in once more into the natural man this had to be regenerated by the Lord, that is, truth from the natural man had to be introduced and joined to good in the rational. When this happens spiritual things have access to the natural man, for now the light of heaven flows in and illuminates things in the natural man, and causes what is there to receive light. The goods there receive the warmth that the light conveys, which is love and charity, whereas the truth receives rays of light, which is faith. It is in this way that spiritual things pass from the rational into natural good and truth. Natural good in that case consists in all the delight and satisfaction gained from having service to the spiritual man as the end in view, and so service to the neighbour, more so to one's country, more so still to the Lord's kingdom, and above all to the Lord. And natural truth consists in all doctrinal teaching and factual knowledge which have wisdom, that is, the performance of those things, as the end in view.
