The number "four" in the Bible represents things being linked together or joined. This is partly because four is two times two, and two represents the ultimate linking between our desire to be good and our understanding of truth. We can also see this in the fact that most buildings are rectangular, with the four sides linking together to make a whole. We also divide directions into four -- north, east, south and west -- and talk about the "four corners" of something meaning all of it. So our special thinking naturally looks at four sides as linking together into a whole.

2618. 'And Jehovah did to Sarah' means a state when the two existed united together - the Lord's Divine spiritual within His Divine celestial. This is clear from the meaning of 'doing', when it has reference to the Lord's Divine, as the entire realization of the effect and consequently of the state; and from the meaning of 'Jehovah', and also of 'Sarah', dealt with just above in 2616. As regards the state when the two existed united together - the Lord's Divine spiritual within His Divine celestial - this is the marriage itself of good and truth, which is the origin of the heavenly marriage. The heavenly marriage is the Lord's kingdom in heaven and on earth, and that is why so many times in the Word the Lord's kingdom is called a marriage, and is compared to a marriage. The reason, which is an arcanum, is that the marriage of Divine Good and Truth, and of Divine Truth and Good, within the Lord is the source of all conjugial love, and through that love the source of all celestial and spiritual love. What further arcana are embodied in these words - 'Jehovah visited Sarah as He had said, and Jehovah did to Sarah as He had spoken' - cannot be made known as they lie beyond description. For these words comprehend the state itself when the Lord's Divine exists united to His Human. Appearances of this state are presented by the Lord to the eyes of the angels by means of heavenly lights, and are illustrated also by means of indescribable representations. But those appearances cannot be presented to men because they would have to be presented by means of objects such as belong to the light of the world, which objects cannot serve to express them. Indeed a description that relies on such things makes them all the more obscure.
