4757. 'And they drew Joseph out and caused him to come up out of the pit' means the help provided by these so that [Divine Truth] is no longer among falsities. This is clear from the meaning of 'drawing out and causing to come up' as delivering and therefore as providing help, dealt with below, and from the meaning of 'the pit' as falsities, dealt with in 4728, and so as its being no longer among falsities. The reason 'drawing out and causing to come up' here means providing help is that truth is what brings help to good. For truth has power attributed to it because good exercises its power by means of truth, 3091, 3563. Furthermore truth is the means by which falsity is recognized, and so by which help is provided so that it is no longer among falsities. This is the reason why it was the Midianites who drew Joseph out and caused him to come up out of the pit, but why it was the Ishmaelites who bought him.

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.
