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).

5414. 'And the sons of Israel came to buy in the midst of others who came' means the wish to acquire spiritual truths, like all other truths, through factual knowledge. This is clear from the meaning of 'the sons of Israel' as spiritual truths (for 'sons' are truths, see above in 5403, and 'Israel' is the celestial-spiritual man coming out of the natural, 4286, 4570, 4598, so that 'the sons of Israel' are spiritual truths within the natural); from the meaning of 'buying' as being acquired; and from the meaning of 'in the midst of others who came' as like all other truths, that is to say, ones acquired through factual knowledge.
