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.

2586. 'For Jehovah had completely closed every womb of Abimelech's house' means sterility, that is to say, of doctrine. This is clear from the meaning of 'completely closing the womb' as preventing conception itself, and from the meaning of 'Abimelech's house' as the good that belongs to the doctrine of faith, from which it is evident that sterility is meant. The reason why in this chapter the name 'God' is used up to this point, and 'Jehovah' for the first time now, is that 'God' is used when truth is the subject but 'Jehovah' when good is the subject. Doctrine is conceived wholly from good as the father, but birth is given to it through truth as the mother, as stated several times already. Here it is the conception of it that is dealt with, and because it is conceived from good the name 'Jehovah' is used; but above it is the birth of it that is dealt with, and because it is given birth through truth the name 'God' is used, as in the previous verse, 'God healed Abimelech, his wife, and his women servants, and they gave birth'.

[2] Similarly in other places in the Word where conception is referred to, as in Isaiah,

Jehovah has called me from the womb. Jehovah who formed me from the womb has said.... I will at that time be precious to Jehovah, and my God will be my strength. Isaiah 49:1, 5.

'Strength' has reference to truth and therefore 'God' is used. In the same prophet,

Thus said Jehovah, your Maker, and He who formed you from the womb. Isaiah 44:2, 24.

And elsewhere. For the same reason also the phrase 'Abimelech's house' is used, which means the good that belongs to the doctrine of faith. As regards 'a house' meaning good, see 2048, 2233, and 'Abimelech' the doctrine of faith, 2509, 2510. The statements that 'they gave birth' and 'the wombs of Abimelech's house were closed on account of Sarah', it is evident, hold a Divine arcanum within them, but this arcanum cannot possibly be disclosed except by means of the internal sense.
