574. And I heard the number of them, signifies their quality perceived. This is evident from the signification of "to hear," as being to perceive (See above, n. 14, 529); also from the signification of "number," as being the quality of the thing treated of (See above, n. 429); here the quality of the falsities of evil conspiring against the truths of good, from which falsities and in favor of which are the reasonings of the sensual man, which are signified by "the number of the armies of the horsemen" (of which 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 those that sat on them, having breast-plates fiery, and hyacinthine, and brimstone-like; and the heads of the horses as the heads of lions; and out of their mouths proceeded fire, and smoke, and brimstone." These words describe the quality here signified by "number." Something of number may seem to be meant here by "number," but in the spiritual world there are no numbers, 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 (See above, n. 203, 336, 429, 430; and in the work on Heaven and Hell 263).

5879. 'Is my father still alive?' means the presence of spiritual good from the natural. This is clear from the representation of Israel, to whom 'father' refers here, as spiritual good from the natural, dealt with in 5801, 5803, 5806, 5812, 5817, 5819, 5826, 5833 (its derivation from the natural being dealt with in 4286); and from the meaning of 'is he still alive?' as the presence of that good. For when he revealed who he was Joseph thought first about his father, whom he knew to be alive. His father was therefore present in his thought at the beginning, and also constantly after that when he talks to his brothers. The reason for this is that the internal celestial, which is 'Joseph', cannot become joined to the truths in the natural, which are 'the sons of Jacob', except through spiritual good from the natural, which is 'Israel'. And once that joining together has taken place they are no longer the sons of Jacob but the sons of Israel; for 'the sons of Israel' are spiritual truths within the natural.
