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.

The number "two" has two different meanings in the Bible. In most cases "two" indicates a joining together or unification. This is easy to see if we consider the conflicts we tend to have between our "hearts" and our "heads" -- between what we want and what we know. Our "hearts" tell us that we want pie with ice cream for dinner; our "heads" tell us we should have grilled chicken and salad. If we can bring those two together and actually want what's good for us, we'll be pretty happy. We're built that way -- with our emotions balanced against our intellect -- because the Lord is built that way. His essence is love itself, or Divine Love, the source of all caring, emotion and energy. It is expressed as Divine Wisdom, which gives form to that love and puts it to work, and is the source of all knowledge and reasoning. In His case the two aspects are always in conjunction, always in harmony. It's easy also to see how that duality is reflected throughout creation: plants and animals, food and drink, silver and gold. Most importantly, it's reflected in the two genders, with women representing love and men representing wisdom. That's the underlying reason why conjunction in marriage is such a holy thing. So when "two" is used in the Bible to indicate some sort of pairing or unity, it means a joining together. In rare cases, however, "two" is used more purely as a number. In these cases it stands for a profane or unholy state that comes before a holy one. This is because "three" represents a state of holiness and completion (Jesus, for instance, rose from the tomb on the third day), and "two" represents the state just before it.
