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.

2937. 'For the full price' means redemption by means of truth. This is clear from the meaning of 'silver' as truth, dealt with in 1551, and from the meaning of 'let him give it to me in - that is, for - silver', as buying, and in the spiritual sense as redeeming. For spiritual people are called 'those bought with silver', see 2048; that is, they are redeemed by means of truth. The reason for this is that they are being regenerated, that is to say, are being initiated into good, by means of the truth of faith. For the spiritual man, unlike the celestial, does not have any perception of good. Instead he knows through truth, and after that acknowledges from truth, that which is good. And when he acknowledges and believes, truth to him becomes good and he experiences it as good whose essential nature is the same as the truth with him. This is why spiritual people are called those redeemed by means of truth. Yet the essential nature of the good is not born and produced from truth, but from the influx of good into truth of that nature.
