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.

2044. That 'a son eight days old' means any beginning whatever to purification is clear from the meaning of 'the eighth day'. 'A week', which consists of seven days, means the entire period of any state and length of time - of reformation, regeneration, or temptation, either of the individual in particular or of the Church in general. So the expression 'week' is used whether the period is one of a thousand years, or of a hundred, or of ten, or else one of days, hours, or minutes, and so on, as may become clear from the places quoted in Volume One, in 728. And because the eighth day is the first day of the following week it here means any new beginning whatever. From this it is also clear that just as circumcision itself was a representative of purification, so also was the time when it took place, namely the eighth day. Not that the uncircumcised on that day entered a purer state and on that account were made pure. Rather even as 'circumcision' was a sign meaning purification, so 'the eighth day' meant that such purification ought to go on all the time and so always to be taking place as if from a new beginning.
