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.

917. And the street of the city was pure gold, like transparent glass. This symbolically means that every truth of the New Church and its doctrine embodies the goodness of love flowing in together with light from the Lord out of heaven.

The description here is like the one in verse 18 above, which says that the city was pure gold, like clear glass, which symbolically means that everything connected with that church embodies the goodness of love flowing in together with light out of heaven from the Lord, as may be seen in nos. 912, 913, with the difference that we are told here that the street of the city was pure gold, like transparent glass, and the street of the city symbolizes the truth of the church's doctrine (no. 501).

That every truth in the church's doctrine from the Word embodies the goodness of love may be seen in nos. 906, 908 above.
