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.

244. And the fourth living creature was like a flying eagle. This symbolizes the Divine truth of the Word in respect to its concepts and the understanding they afford.

Eagles have various symbolic meanings, but flying eagles symbolize concepts which lead to understanding, since when they fly, they recognize and see. They also have sharp eyes so as to see keenly, and eyes symbolize the intellect (nos. 48, 214).

To fly means, symbolically, to perceive and teach, and in the highest sense, which has the Lord as its subject, it means to foresee and provide.

That this is the symbolic meaning of eagles in the Word is apparent from the following passages:

Those who wait on Jehovah shall renew their strength; they shall mount up on wings like eagles. (Isaiah 40:31)

To mount up on wings like eagles means to be raised into concepts of truth and goodness and so into intelligence.

Does the hawk fly by your wisdom...? Does the eagle mount up at your command...(and) spy out its food? Its eyes observe from afar. (Job 39:26-27, 29)

The eagle here describes a faculty for recognizing, understanding, and foreseeing, and the fact that this does not result from one's own intelligence.

(Jehovah,) who satisfies your mouth with good, so that you are renewed in your youth like an eagle. (Psalms 103:5)

To satisfy the mouth with good means to give understanding by means of concepts. Thus an analogy is made with an eagle.

A great eagle with large wings and long pinions... came upon Lebanon and took from the cedar a little branch... Then it took some of the seed of the land and planted it in the field of a growing crop..., and it grew and became a vine... But there was another great eagle..., to which the vine bent its roots... (Ezekiel 17:1-8)

The two eagles here describe the Jewish and Israelite churches, each in respect to its concepts of truth and consequent intelligence.

In an opposite sense, however, eagles symbolize false concepts, by which the intellect is corrupted, as in Matthew 24:28, Jeremiah 4:13, Habakkuk 1:8-9, and elsewhere.
