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.

575. 'The days of man were to be a hundred and twenty years' means that he ought to have remnants of faith. At verses 3, 4 of the previous chapter it was stated that 'days' and 'years' meant periods of time and states, and that the most ancient people meant states and changes in the states of the Church by the numbers which they compounded variously. The exact nature of their computation of things that had to do with the Church is one of those matters that have been lost. Here in like manner numbers of years occur, whose meaning nobody can possibly know unless he knows what is concealed in each of the numbers 1-12, and so on. It is quite apparent that they embody some arcanum or other, for in saying that they would live a hundred and twenty years this verse contradicts those that go before it. Nor subsequently did they live a mere hundred and twenty years, as is clear from what Chapter 11 says about those who lived after the Flood - that Shem lived 500 years after he beget Arpachshad, Arpachshad 407 years after he beget Shelah, Shelah 403 years as well after he beget Eber, and Eber 430 years after he beget Peleg. Chapter 9:28 says that Noah lived 350 years after the Flood; and other examples could be given. What the number 120 embodies however is clear merely from the numbers to and 12, for 120 is the product of 10 times 12. It means remnants of faith. In the Word the number ten has the same meaning as tenths, representing remnants which are preserved by the Lord within the internal man. And since these are the Lord's alone they are holy. The number twelve means faith, that is, all things belonging to faith in their entirety. So this composite number means remnants of faith.
