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.

529. Verse 13. And I saw, and I heard one angel flying in midheaven, signifies the Lord enlightening all in the heavens respecting the state of the church at its end. This is evident from the signification of "to see and to hear," as being to open the understanding to perceive (of which presently); and from the signification of "angel," as being the Lord. That "angels" in the Word mean Divine truth proceeding from the Lord, thus the Lord Himself in relation to Divine truth, may be seen above (n. 130, 200, 302), here the Lord manifesting what the church is to be in the last times in respect to the reception of Divine truth. Also from the signification of "to fly," as being to enlighten and give understanding (of which presently); also from the signification of "in midheaven," as being in the whole heaven, or all who are in the heavens (that "in the midst" signifies in the whole and thus all, see above, n. 213). From this it can be seen that "I saw, and I heard one angel flying in mid-heaven," signifies the enlightenment of all who are in the heavens respecting the state of the church at its end. Enlightenment respecting the state of the church at its end is meant, because this is what is treated of in what follows. "To see and to hear" signifies to open the understanding to perceive, because "to see" signifies to understand, and "to hear" to perceive (that "to see" signifies to understand, see above, n. 260; and that "to hear" signifies to perceive, also above n. 14, 108).

[2] "To fly" signifies, in reference to the Lord, to enlighten, because "to fly" is said of the understanding, and of the extension of its vision round about, therefore in reference to the Lord, "to fly" signifies the enlightenment of the understanding. That in reference to the Lord, "to fly" signifies omnipresence, may be seen above (n. 282); consequently it signifies also enlightenment, for where the Lord is present there is enlightenment. "To fly" has the same signification in David:

God rode upon a cherub, He did fly, and was borne upon the wings of the wind (Psalms 18:10; 2 Samuel 22:11).

A "cherub" signifies the inmost heaven, "to ride" signifies to give understanding and to enlighten; "to fly" and "to be borne upon the wings of the wind" have a like meaning; but "to ride" here signifies to give understanding to and to enlighten here the inmost heaven, which is signified by a "cherub;" "to fly" also signifies to give understanding to and to enlighten the middle heaven; while "to be borne upon the wings of the wind" signifies to give understanding to and to enlighten the ultimate heaven. (That "to ride" signifies to give understanding, see above, n. 355, 364; and that a "cherub," signifies the inmost heaven, n. 313, 322, 362, 462.) "To fly" signifies to enlighten the middle heaven, because that heaven is the spiritual heaven, and spiritual things in the Word are signified by various birds, and by their wings and flights. "To be borne upon the wings of the wind" signifies to enlighten the ultimate heaven, because "wings" are for flight, and here signify enlightenment, and "wind" signifies the spiritual of that heaven; thus all this describes the omnipresence of the Lord in the heavens, thence also the enlightenment of the understanding; for as was said above, where the Lord is present there is enlightenment.
