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.

4635. The preliminary sections of the chapters of Genesis immediately before this one contain explanations of what the Lord foretold in Matthew 24 about the final period of the Church. This being what those sections contain, and because Chapter 25 of that gospel goes on to deal with the same matters, let an explanation now be given of the internal sense of those matters in the order in which they come, which in the letter is as follows,

Then the kingdom of heaven will be like ten virgins who took their lamps and went out to meet the Bridegroom. Five of them however were wise, but five were foolish. Taking their lamps the foolish did not take oil with them, whereas the wise took oil in their vessels with their lamps. While the Bridegroom was tarrying they were all drowsy and went to sleep. At midnight there was a shout, Behold, the Bridegroom is coming; go out to meet Him. Then all those virgins were roused and they trimmed their lamps. But the foolish said to the wise, Give us some of your oil, for our lamps are going out. But the wise replied, saying, Perhaps there will not be enough for us and for you; go rather to those who sell and buy for yourselves. While they were going to buy however, the Bridegroom came, and those who were ready went in with Him to the wedding feast; and the door was shut. Afterwards the remaining virgins came also, saying, Lord, Lord, open to us. But He replying said, Truly, I say to you, I do not know you. Watch therefore, for you do not know the day, nor the hour, in which the Son of Man will be coming. Matthew 25:1-13.
