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.

135. And thou holdest My name, signifies the acknowledgment of the Divine in the Human of the Lord, as well as all things of love to Him and faith in Him. This is evident from what has been shown above about the signification of the "name" of Jehovah, Lord, and Jesus Christ n. 102. By the Lord's "name" in the Word is meant primarily the acknowledgment of the Divine in His Human, because all things of love and faith are from that; for Divine goods which are of love, and Divine truths which are of faith, proceed from no other source than from the Lord alone; and these cannot flow in with man unless he thinks of the Lord's Divine at the same time that he thinks of His Human; nor is His Divine separate from the Human, but it is in the Human (as may be seen above, n. 10, 26, 49, 52, 77, 97, 113, 114). I can aver, from all experience of the spiritual world, that no one is in the truths of faith and in the goods of love except he who thinks of the Lord's Divine at the same time that he thinks of His Human; as also that no one is spiritual, or is an angel, unless he has been in that thought and consequent acknowledgment in the world. Man must needs be conjoined to the Divine by his faith and love in order to be saved; and all conjunction is with the Lord; and to be conjoined to His Human only, and not to His Divine at the same time, is not conjunction; for the Divine saves, but not the Human apart from the Divine. (That the Human of the Lord is Divine, see The Doctrine of the New Jerusalem 280-310.)
