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.

499. And an earthquake, signifies changes of state of the church. This is evident from the signification of "earthquakes," as meaning changes of state of the church (of which above, n. 400. In the same place it is shown that in the spiritual world the lands quake, and the hills and mountains are shaken, when the state of the church there is changed for the worse and evil and falsity begin to rule. Earthquakes occur in the spiritual world for the reason that all the lands there are from a spiritual origin, and are changed with the changing of the church with those there. Where the church is flourishing the country is beautiful, and full of paradises, flower gardens, and lawns; but where the church is perverted, it is unbeautiful, and full of deserts and rocks; and the change is in exact accord with the decline of the church from good and truth into evil and falsity; but this takes place only in the lower parts (on this see in the work on Heaven and Hell 156, and elsewhere). Such being the origin of the lands there it can be seen that earthquakes occur there from changes in the state of the church.
