435. As regards 'the man and his wife' here being used to mean the new Church which earlier on was meant by 'Adah and Zillah', this nobody can know or deduce from the sense of the letter, for previously 'the man (homo) and his wife' meant the Most Ancient Church and its descendants. The point is clear however from the internal sense, and also from the fact that a little further on, in verses 3-4 of the next chapter, reference is again made, though the wording is entirely different, to the man and his wife begetting Seth. At that point the first generation of the descendants of the Most Ancient Church is meant. Unless something different were meant at this point there would be no need to say the same thing again. A parallel to this exists in Chapter 1, where the subject is the creation of man, and also of the fruits of the earth, and of beasts; followed by Chapter 2, where similar events are described, the reason for the similarity being, as has been stated, that Chapter 1 deals with the creation of the spiritual man, Chapter 2 with the creation of the celestial man. When this kind of repetition of one and the same person or thing occurs, something different is meant on the first occasion from the second. But the exact meaning cannot possibly be known except from the internal sense. The actual train of thought in like manner establishes the meaning here. And there is the added consideration that 'man and wife' is a general expression meaning that Church, which is the subject here and from which the new Church was born.

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.
