9757. 'Their pillars, and the bases of these, ten' means the quantity also of supporting forms of good, and of truths springing from these, needed for the purposes they have to serve. This is clear from the meaning of 'pillars' as forms of good which provide support, as above in 9747; from the meaning of 'bases' as truths springing from good which also provide support, dealt with above in 9748; and from the meaning of 'ten' as a sufficient amount or the amount needed for the purposes they have to serve. The situation with the forms of good and the truths that provide support is similar to that with the actual truths that are being supported, 9756; therefore 'ten' here implies much the same as 'fifty' or 'five', that is to say, the amount needed for the purposes they have to serve. Ten is also a product of five when multiplied, being the double of it, and multiple numbers are similar in meaning to the simple ones which are their factors, 5291, 5335, 5708, 7973.

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.
