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.

In some casual references “first” has a pretty literal meaning, as the beginning of a group; on a deeper level the “first” represents the entire group. In connection with measurements of time -- days, months, hours etc. -- it means the beginning of a new spiritual state. It is also used in connection with the Lord, who is the “first” of all existence, because everything is a product of His love. “First” is perhaps most commonly used, however, to represent what people love and desire, because what we love and desire is “first” in us, with our thoughts and intellect following. If we love people around us and desire to serve them, our ideas will follow and find ways to do it. It does not, however, work the other way around -- having ideas of how to be good won't mean anything if we lack the desire to be good. Our loves, then, contain the key elements of all that we are.
