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.
Isaiah 45:11-25
11
Thus says Yahweh, the Holy One of Israel, and his Maker: "You ask me about the things that are to come, concerning my sons, and you command me concerning the work of my hands!
12
I have made the earth, and created man on it. I, even my hands, have stretched out the heavens; and I have commanded all their army.
13
I have raised him up in righteousness, and I will make straight all his ways. He shall build my city, and he shall let my exiles go free, not for price nor reward," says Yahweh of Armies.
14
Thus says Yahweh: "The labor of Egypt, and the merchandise of Ethiopia, and the Sabeans, men of stature, shall come over to you, and they shall be yours. They will go after you. They shall come over in chains; and they will bow down to you. They will make supplication to you: 'Surely God is in you; and there is none else. There is no other God.
15
Most certainly you are a God who hidden yourself, God of Israel, the Savior.'"
16
They will be disappointed, yes, confounded, all of them. Those who are makers of idols will go into confusion together.
17
Israel will be saved by Yahweh with an everlasting salvation. You will not be disappointed nor confounded to ages everlasting.
18
For thus says Yahweh who created the heavens, the God who formed the earth and made it, who established it and didn't create it a waste, who formed it to be inhabited: "I am Yahweh; and there is no other.
19
I have not spoken in secret, in a place of the land of darkness. I didn't say to the seed of Jacob, 'Seek me in vain.' I, Yahweh, speak righteousness. I declare things that are right.
20
"Assemble yourselves and come. Draw near together, you who have escaped from the nations. Those have no knowledge who carry the wood of their engraved image, and pray to a god that can't save.
21
Declare and present it. Yes, let them take counsel together. Who has shown this from ancient time? Who has declared it of old? Haven't I, Yahweh? There is no other God besides me, a just God and a Savior; There is no one besides me.
22
"Look to me, and be saved, all the ends of the earth; for I am God, and there is no other.
23
I have sworn by myself, the word has gone out of my mouth in righteousness, and will not return, that to me every knee shall bow, every tongue shall take an oath.
24
They will say of me, 'There is righteousness and strength only in Yahweh.'" Even to him shall men come; and all those who were incensed against him shall be disappointed.
25
In Yahweh shall all the seed of Israel be justified, and shall glory.
