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.

3819. 'The name of the elder was Leah' means the nature of the affection for external truth; 'and the name of the younger Rachel' means the nature of the affection for internal truth. This is clear from the representation of 'Leah' as the affection for external truth, and of 'Rachel' as the affection for internal truth, both dealt with in 3793; and from the meaning of 'the name' as the nature of, dealt with in 144, 145, 1754, 1896, 2009, 2724, 3006. Leah is called 'the elder' because external truth is learned first, and Rachel 'the younger' because internal truth is learned from then on after that; or what amounts to the same, a person first of all feels an affection for external truths, and from then on after that an affection for internal truths. external truths provide the basic outline for internal truths, for they are the general outlines into which particular details are added. Unless a person has a general outline of the idea of a thing he does not make sense of any particular aspect of it. This explains why the literal sense of the Word contains general truths but the internal sense particular truths. General truths are called external, but particular truths internal. And because truths devoid of affection are not truths because there is no life to them, the affections for them are therefore meant when external and internal truths are referred to.
