Arcana Coelestia #487
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.
Revelation 21:12-24
12
having a great and high wall; having twelve gates, and at the gates twelve angels; and names written on them, which are the names of the twelve tribes of the children of Israel.
13
On the east were three gates; and on the north three gates; and on the south three gates; and on the west three gates.
14
The wall of the city had twelve foundations, and on them twelve names of the twelve Apostles of the Lamb.
15
He who spoke with me had for a measure, a golden reed, to measure the city, its gates, and its walls.
16
The city lies foursquare, and its length is as great as its breadth. He measured the city with the reed, Twelve thousand Twelve stadia. Its length, breadth, and height are equal.
17
Its wall is one hundred forty-four cubits, by the measure of a man, that is, of an angel.
18
The construction of its wall was jasper. The city was pure gold, like pure glass.
19
The foundations of the city's wall were adorned with all kinds of precious stones. The first foundation was jasper; the second, sapphire; the third, chalcedony; the fourth, emerald;
20
the fifth, sardonyx; the sixth, sardius; the seventh, chrysolite; the eighth, beryl; the ninth, topaz; the tenth, chrysoprasus; the eleventh, jacinth; and the twelfth, amethyst.
21
The twelve gates were twelve pearls. Each one of the gates was made of one pearl. The street of the city was pure gold, like transparent glass.
22
I saw no temple in it, for the Lord God, the Almighty, and the Lamb, are its temple.
23
The city has no need for the sun, neither of the moon, to shine, for the very glory of God illuminated it, and its lamp is the Lamb.
24
The nations will walk in its light. The kings of the earth bring the glory and honor of the nations into it.
