487. 'Days means periods of time and states in general. This has been shown in Chapter 1, where the 'days of creation' have no other meaning. In the Word it is very common for a whole period of time to be called 'a day', as it clearly is in the present verse and in verses 5, 8, 11, 14, 17, 20, 23, 27, 31, below; and therefore the states that belong to periods of time in general are meant by 'days' as well. And when 'years' is attached, then periods of years mean the natures of those states, and so the states in particular.

[2] The most ancient people had their own particular numbers which they would use to mean different aspects of the Church - for instance, the numbers three, seven, ten, twelve, and many which they obtained from these and other numbers - and in so doing incorporated states of the Church. These numbers therefore contain arcana that would require considerable effort to unravel. Really a number was an evaluation of the states of the Church. The same feature occurs throughout the Word, especially in the prophetical. And the religious ceremonies of the Jewish Church also entail numbers specifying periods of time as well as quantities; for example, in connection with sacrifices, minchahs, oblations, and other practices, which in every case have special reference to holy things. Consequently eight hundred in this verse, nine hundred and thirty in the next, and the numbers of years mentioned in the verses that follow after that, embody in particular more matters than can possibly be retold; matters, that is to say, which have to do with changes in the state of their Church in relationship to their own general state. Later on, in the Lord's Divine mercy, the meaning of the simple numbers up to twelve will be given, for without knowing these first of all no one can grasp what compound numbers mean.

3498. 'I do not know the day of my death' means the life within the natural. This is clear from the meaning of 'day' as state, dealt with in 23, 487, 488, 493, 893, 2788, and from the meaning of 'death' as rising again or awakening into life, dealt with in 3326. 'The day of death' accordingly means a state of awakening to life, or what amounts to the same, it means life - the life within the natural, it is evident, being meant in particular here, because that life is the subject here. What is implied in all this does not become clear unless one knows about the life of the rational, and the life of the natural, or what amounts to the same, about the life of the internal man and the life of the external man. The life of the rational or internal man is distinct and separate from that of the natural or external man, so distinct indeed that the life of the rational or internal man may exist quite independently of the life of the natural or external man; but the life of the natural or external man cannot exist apart from that of the rational or internal man. For the external man lives from the internal man, so much so that if the life of the internal man ceased to be, the life of the external man would instantly be no more. Exterior things are accordingly dependent on interior in the way that things which are posterior exist from those that are prior, or as an effect exists from its efficient cause. For if the efficient cause ceased to be, the effect would instantly be no more. The same is also so with the life of the external man in relation to the life of the internal man.

[2] This may be seen even more clearly in the human being, for while a person is in the world, that is, while he lives in the body, his rational is distinct and separate from the natural, so much so that he can be raised above the level of external sensory perceptions which belong to the body, and even to a certain extent above the level of inner sensory perceptions which belong to his natural man, and to be aware on the level of his rational, and so of spiritual thought. This is even more evident from the fact that when a person dies he leaves behind him altogether the external sensory perceptions that belong to the body, retaining at the same time the life of his interior man. Indeed he brings with him even the facts that exist in the external or natural memory, though he does not have the use of them, see 2475-2477, 2479-2483, 2485, 2486. From this it is evident that the rational or internal man is distinct and separate from the external man. But while a person is living in the body his rational does not seem to be distinct and separate from the natural, the reason being that he is living in the world or the natural order. That being so the life of the rational manifests itself within the natural, so much so that the rational does not seem to have any life at all if the natural does not at the same time have any. The amount of life that the rational seems to have in this case depends on how far the natural corresponds to it - see above in 3493. From this it may be seen that there is a corresponding life in the natural, which life is meant by the words which Isaac addressed to Esau, 'I do not know the day of my death'. For 'Isaac' represents the rational, and 'Esau' the natural, in both cases as regards good.
