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.

5858. Much experience has taught me that anything spirits think or say by drawing on a person's memory they regard as their own, existing within themselves. If told that their idea is not true they are highly indignant; for that kind of sensory illusion holds sway among them. I have asked them - to convince them that their idea is not true - how it is that they can talk to me in my own mother tongue, having had absolutely no knowledge at all of it during their lifetime. How do they know the other languages that I have mastered without learning a single one for themselves? Do they really think those languages are theirs? I have read even the Hebrew language to them which they, including young children, understood to the same extent as I understood it, but not beyond. They have also been shown that all the knowledge present with me is present with them. This has convinced them that when they come to a person they enter into possession of everything he knows, and that in believing it is their own they are holding to a false idea. They do have knowledge that is their own, but they are not allowed to draw on it, to the end that they may serve a person through the knowledge he has; and there are many other reasons for this as well, dealt with in 2476, 2477, 2479. Indeed very great confusion would result if spirits were to flow in with what came from their own memory, 2478.
