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.

4210. 'Jacob offered a sacrifice on the mountain' means worship founded on good that stems from love. This is clear from the meaning of 'a sacrifice' as worship, dealt with in 922, 923, 2180, and from the meaning of 'the mountain' as good that stems from love, 795, 796, 1430. 'A sacrifice' means worship because sacrifices and burnt offerings were the major features of all worship in the later representative Church, which was the Hebrew Church. They also used to sacrifice on mountains, as is clear from various places in the Word, because 'mountains' on account of their height meant the things which were high, such as those are which belong to heaven and are called heavenly; and having this meaning they also meant, in the highest sense, the Lord, whom they called the Most High. It was the outward appearance that led them to think in this way, for the things that are interior give the appearance of being higher, as heaven does with man. Heaven is interiorly within him, and yet he supposes it to be on high. This is the reason why, when the expression 'high' is used in the Word, that which is interior is meant in the internal sense.

[2] In the world people inevitably take heaven to be on high. One reason why they do so is that the word 'heaven' is used for the visible expanse which encircles them on high and another is that man is a dweller within time and space and so thinks from ideas derived from these. And a further reason is that few are aware of what anything interior may be, and fewer still are aware that neither place nor time exist there. This is why the mode of expression employed in the Word is one that accords with the ideas present in man's thought. If it had not accorded with those ideas but with angelic ideas man would have perceived nothing at all, but everyone would have stood wondering what it was and whether it was anything at all, and so would have rejected it as being devoid of anything intelligible.
