3390. 'It happened, because his days were prolonged for him there' means a state of reception. This is clear from the meaning of 'prolonging for him there', that is to say, for Isaac, as this: When Divine Good, represented by Isaac, had been present for some time truth would be received, for it is the reception of truth by those who are spiritual that is the subject in the internal sense; and from the meaning of 'days' as states, dealt with in 23, 487, 488, 493, 893, 2788.

493. There is no need to pause too long over the consideration that 'days' and 'years mean periods of time and states. Only this need be stated here, that in the world periods of time and measurements to which numbers may be applied are indispensable, for they belong within the ultimate realms of nature. But whenever such application occurs, the numbers of days and years, and also the numbers applied to measurements, mean something which is completely different from periods of time or from measurements, and which is determined by the meaning of the number used, as in the statements about there being six days for work, and the seventh being holy, which are dealt with above; in the statement about a jubilee having to be announced every forty-ninth year and celebrated in the fiftieth; about the tribes of Israel being twelve, the same number as the Lord's Apostles; and about there being seventy elders, the same number as the Lord's disciples. And there are many other examples where the numbers mean some special characteristic completely different from the persons or objects to which they apply. And when completely separated one from the other the states meant by the numbers are then left.
