3281. And Isaac was a son of forty years. That this signifies from His own power by temptation combats, is evident from the representation of Isaac, as being the Divine rational, as already frequently explained; from the signification of “forty,” as being temptations (n. 730, 862); and from the signification of “years,” as being states (n. 23, 487, 488, 493, 893, 2788). Hence the internal sense of these words is that the Lord made His rational Divine also as to truth, by temptation combats, thus by His own power. (That the Lord by His own power through temptations admitted into Himself made all the human in Himself Divine, was shown above, n. 1616, 1663, 1668, 1690, 1787, 2083, 2523, 2632, 2776, 3030, 3043, 3141)

487. That by “days” are signified times and states in general, was shown in the first chapter, where the “days” of creation have no other signification. In the Word it is very usual to call all time “days” as is manifestly the case in the present verse, and in those which follow, 8, 11, 14, 17, 20, 23, 27, 31 (5, 8, 11, 14, 17, 20, 23, 27, 31); and therefore the states of the times in general are likewise signified by “days;” and when “years” are added, then by the seasons of the years are signified the qualities of the states, thus states in special. The most ancient people had their numbers, by which they signified various things relating to the church, as the numbers “three” “seven” “ten” “twelve” and many that were compounded of these and others, whereby they described the states of the church; wherefore these numbers contain arcana which would require much time to explain. It was an account or reckoning of the states of the church. The same thing occurs in many parts of the Word, especially the prophetical. In the rites of the Jewish Church also there were numbers, both of times and measures, as for instance in regard to the sacrifices, meat-offerings, oblations, and other things, which everywhere signify holy things, according to their application. The things here involved, therefore, in the number “eight hundred” and in the next verse, in the number “nine hundred and thirty” and in the numbers of years in the verses following-namely, the changes of state of their church as applied to their own general state-are too many to be recounted. In a future part of this work, of the Lord’s Divine mercy we shall take occasion to show what the simple numbers up to “twelve” signify, for until the signification of these is known, it would be impossible to apprehend the signification of the compound numbers.
