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.

2507. 'Of Sarah his wife' means spiritual truth joined to the celestial. This is clear from the meaning of 'Sarah his wife' as intellectual truth joined to Divine Good, or what amounts to the same, spiritual truth joined to the celestial, dealt with in 1468, 1901, 2063, 2065, 2172, 2173, 2198. What the spiritual is, and what the celestial, has been stated quite often already, see 1155, 1577, 1824, 2048, 2088. That is called the celestial which consists in good, that is, which consists in love to the Lord and in charity towards the neighbour; and that is called the spiritual which consists in truth, that is, which consists in faith deriving from love and charity.
