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.

When we eat, our bodies break down the food and get from it both energy and materials for building and repairing the body. The process is similar on a symbolic level in the Bible. Food represents the desire for good and the insight that comes from that desire for good – goodness and understanding that come from the Lord. But to put them to use we have to take them in and make them our own – which is spiritual eating.
