251. The reason why the “serpent” means all evil in general, and specifically the love of self, is that all evil has had its rise from that sensuous part of the mind, and also from that memory-knowledge [scientifico], which at first were signified by the “serpent;” and therefore it here denotes evil of every kind, and specifically the love of self, or hatred against the neighbor and the Lord, which is the same thing. As this evil or hatred was various, consisting of numerous genera and still more numerous species, it is described in the Word by various kinds of serpents, as “snakes” “cockatrices” “asps” “adders” “fiery serpents” “serpents that fly” and “that creep” and “vipers” according to the differences of the poison, which is hatred. Thus we read in Isaiah:

Rejoice not thou, whole Philistia, because the rod which smiteth thee is broken, for out of the serpent’s root shall go forth a cockatrice, and his fruit shall be a flying fire-serpent (Isaiah 14:29).The “serpent’s root” denotes that part of the mind, or that principle, which is connected with the senses and with memory-knowledge [est sensuale et scientificum]; the “cockatrice” denotes evil originating in the falsity thence derived; and the “flying fire-serpent” the cupidity that comes from the love of self. By the same Prophet also similar things are elsewhere thus described:

They hatch cockatrice’s eggs, and weave the spider’s web; he that eateth of their eggs dieth, and when it is crushed there cometh out a viper (Isaiah 59:5).

The serpent described here in Genesis is called in the Revelation the “great and red dragon” and the “old serpent” and also the “devil and satan” that “deceives the whole world” (Revelation 12:3, 9; 20:2), where, and also in other places, by the “devil” is not meant any particular devil who is prince over the others, but the whole crew of evil spirits, and evil itself.

3084. 'And went up' means a raising up. This is clear from the meaning of 'going up' as being raised up. The expression 'raised up' is used to describe from what is lower to what is higher, and because it is used to describe this it is also used to describe from what is exterior to what is interior, for the two are one and the same. Indeed what is lower and higher in human thought is exterior and interior in angelic thought, as with the idea of heaven. By men heaven is seen as that which is higher, but by angels as that which is interior. It is similarly so with the natural with man. In relation to his spiritual it is exterior, while the spiritual in turn is exterior in relation to the celestial. Or what amounts to the same, factual knowledge which belongs to the natural man is exterior in relation to truth, while truth is exterior in relation to good. Therefore also factual knowledge in relation to truth is called a covering as well as a garment, and so in a similar way is truth in relation to good.

[2] This explains why the expressions 'going up' to Jerusalem, but 'coming down' from Jerusalem are used; also 'going up' from Jerusalem to Zion, and 'coming down' from Zion to Jerusalem; for the parts surrounding Jerusalem mean the exterior features of the Church, Jerusalem meaning the more interior features and Zion the inmost. Since in the internal sense this verse describes the initial stage in the raising up of truth from the natural man to the rational man, therefore it is first of all said here that the affection for truth represented by Rebekah 'went down to the spring' and shortly after that 'went up'. For as stated above in 3074, Divine love flows into the affection for good, and from there into the affection for truth, and in so doing brings life and light to the things that are in the natural man, and at the same time orders them. This is the meaning of 'going down'. In this way truths are raised up from the natural man into the rational man where they are joined to good. This is the meaning of 'going up'.
