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.

1866. 'From the river of Egypt to the great river, the river Phrath' means the extension of spiritual and celestial things, 'to the river of Egypt' being the extension of spiritual things, 'to the river Phrath' the extension of celestial things. This is clear from the meaning of 'the river of Egypt' and from the meaning of 'the great river' or the Euphrates. That these rivers mean the extension of spiritual and celestial things becomes clear from the meaning of 'the land of Canaan' as the Lord's kingdom in heaven and on earth, in which kingdom there is nothing else than the spiritual things of faith and the celestial things of mutual love. Consequently nothing else can be meant by the borders of the land of Canaan than the extension of those things. For what the land of Canaan is, what the river of Egypt is, and what the great river, the Euphrates, is, the inhabitants of heaven do not know at all. Indeed they do not know what the borders of any land are; but they do know what the extension of spiritual and celestial things is, and the range and limits of the states belonging to them. These are the things which those in heaven have in mind when such things in the letter are read by man, so that the letter and its historical sense which has served as a basis for heavenly ideas disappears.

[2] The reason why 'the river of Egypt' means the extension of spiritual things is that 'Egypt' means factual knowledge which, together with the rational concepts and the intellectual concepts which a person has, constitute spiritual things, as stated already in 1443 and elsewhere in this volume. And as to why in the internal sense 'Egypt' means factual knowledge, see 1164, 1165, 1186, 1462. That 'the river Euphrates' means the extension of celestial things becomes clear from the lands which that river bounded and marked off from the land of Canaan, and by which in many other places facts and the cognitions of celestial things are meant. Here however because it is called 'the river', and 'the great river', they are nothing other than celestial things and the cognitions of them, for 'the great river' and greatness are used in reference to these.
