2726. That 'Abraham sojourned in the land of the Philistines for many days' means that the Lord allied to the doctrine of faith very many things drawn from a knowledge of human cognitions is clear from the meaning of 'sojourning' as giving instruction, dealt with in 1463, 2025, from the representation of 'Abraham' as the Lord, dealt with in 1965, 1989, 2011, 2501, from the meaning of 'the land of the Philistines' or Philistia as knowledge of cognitions, dealt with in 1197, 1198, and from the meaning of 'days' as the state of whatever it is that is the subject, 23, 487, 488, 493, 893. Here because the subject is the cognitions from which the facts and rational ideas are obtained, and because the expression 'many days' is used, the meaning is relatively 'very many things' From verse 22 onwards the subject has been the rational ideas based on human factual knowledge, which were allied to the doctrine of faith, as is evident from the explanation given. The present verse forms the conclusion to these considerations. As regards the actual subject, since this in itself is rather profound, and since the same subject is dealt with extensively further on, in Chapter 26, let any further explanation here be put off till that chapter.

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.
