3019. 'Abraham said to his servant, the oldest of his house' means the ordering and influx of the Lord into His Natural, meant by 'the servant, the oldest of the house'. This is clear from the meaning of 'saying' here as commanding since it is a servant to whom Abraham's words are addressed; and since the subject is the re-arranging by the Divine of the things that exist in the natural man, ordering and influx are meant. For everything that is done in the natural or external man is an ordering by the rational or internal, and is effected by means of influx. The use of the expression 'the servant, the oldest of the house' to mean the natural, or the natural man, may be seen from the meaning of 'a servant' as that which is lower and serves what is higher, or what amounts to the same, that which is exterior and serves what is interior, see 2541, 2567. All things that belong to the natural man, as facts of every kind do, are nothing else than a body of servants, for they serve the rational by enabling it to be thoroughly fair in what it thinks and righteous in what it wills. That 'the oldest of the house' is the natural man becomes clear from what follows below.

2758. The truth that genuine conjugial love is heaven is represented in the kingdoms of nature, for nothing exists in the whole natural order which is not in some way representative of the Lord's kingdom in general, since the natural kingdom has its entire origin in the spiritual kingdom. That which is without an origin prior to itself is nothing, for nothing exists without connection from a cause and so from an end. That which is without such connection collapses in an instant and ceases to be anything. This then explains where the representatives of the Lord's kingdom within the kingdoms of nature have their origin. The truth that conjugial love is heaven is evident from the metamorphosis of caterpillars into pupae or chrysalises and then into creatures that fly. For when the time arrives for them to be wedded - which is when they shed their earthly form, or their caterpillar state - they are adorned with wings and become creatures that fly, at which point they are raised up into the air, which is their heaven. In the air they play together, make marriages, lay eggs, and are nourished by the juices from flowers. At that time also they exist in their beauty, for their wings are tinged with gold, silver, and other lovely shades. Such things as these are what the inclination to pair off in marriage produces among such insignificant and tiny creatures.
