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.

9717. 'Square shall the altar be' means that which for this reason is righteous. This is clear from the meaning of 'square' as what is righteous, dealt with below; and from the meaning of 'the altar' as what is representative of the Lord and of the worship of Him, so that 'square shall the altar be' means what is righteous within the Lord, and consequently within worship. Worship is called righteous when the good and the truth contained within it spring from the Lord and not from the person, for the Lord alone is the source of that which is righteous, 9263. The meaning of 'square' as what is righteous has its origin in representative signs in the next life. There forms of good present themselves as round shapes, and forms of good belonging to the external man, which are called righteous acts, as square shapes. Truths and right ideas however present themselves as linear and triangular ones. So it is then that 'square' means what is righteous, as does the squareness of the altar of incense, Exodus 30:2; also the squareness of the breastplate of judgement when doubled, Exodus 28:16; as well as the new Jerusalem's being square-shaped, Revelation 21:16. The new Jerusalem there is the Lord's New Church which will take the place of the one that is ours at the present day, its external good, which is righteous, being meant by 'square-shaped'.
