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.

303. Heaven's Union with Us through the Word

People who think from their deeper rationality can see that there is a connection of all things, through intermediate ones, with a First, and that anything that is not so connected will disintegrate. When they think about it, they know that nothing can exist on its own, but requires something prior to itself, which means that everything goes back to that First. They know that the connection with what is prior is like that of an effect with its efficient cause, since when the efficient cause is removed, the effect comes apart and collapses. Since this has been the thought of the learned, they have both seen and pronounced that existence is a constant becoming, so that all things are constantly coming into being - that is, existing - from that First from which they originated.

But there is no way to explain briefly the nature of that connection of everything with what is prior and therefore with the First that is the source of everything, because it is varied and diverse. We can say generally only that there is a connection of the natural world with the spiritual world that results in a correspondence between everything in the natural world and everything in the spiritual world. (On this correspondence, see 103-115, and on the connection and consequent correspondence of everything in us with everything in heaven, see 87-102)
