574. And I heard the number of them.- This signifies their quality perceived, as is evident from the signification of hearing, as denoting to perceive (see above, n. 14, 529); and from the signification of number, as denoting the quality of the thing treated of, concerning which, see above (n. 429); here, the quality of the falsities of evil that conspire against the truths of good, from which and on behalf of which are the reasonings of the sensual man, which are signified by the number of the armies of the horsemen, spoken of just above. But the quality of these is further described in the next verse in these words: "And thus I saw the horses in the vision, and them that sat on them, having breast-plates fiery, and purple, and sulphurous; and the heads of the horses as the heads of lions; and out of their mouths went forth fire, smoke, and brimstone." These words are expressive of the quality that is here signified by number. Some reference to number appears to be meant here by number, but in the spiritual world numbers do not exist, for spaces and times there are not measured and determined by numbers, as in the natural world, therefore all numbers, in the Word, signify things, and the number itself signifies the quality of the thing treated of, see above (n. 203, 336, 429, 430); and in Heaven and Hell 263).

203. (Verse 7) And to the angel of the church in Philadelphia write. That this signifies those of the church who are in the faith of charity is evident from the things written to the angel of this church, understood in the internal sense. For, as said above (n. 20), by the seven churches are not meant seven churches, but all who belong to the church, or all things pertaining to man which constitute the church; for by seven in the Word are meant all persons, and all things, because by each number mentioned in the Word is signified something either of thing or state, as is very evident in this prophetic book, in which numbers are so frequently mentioned. The same is evident from Ezekiel (chap. 40-48), where the new temple and the new earth are described, which is done by measures given in numbers. By the new temple and the new earth is there meant the New Church, and by each number or each measure is signified something belonging to the church. (That all numbers in the Word signify things and states, may be seen in the work, Heaven and Hell 263.)
