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.

3971. 'It happened, when Rachel had borne Joseph' means acknowledgement of the spiritual represented by Joseph. This is clear from the meaning of 'bearing' as acknowledging, dealt with in 3905, 3911, 3915, 3919; from the representation of 'Rachel' as the affection for interior truth, dealt with in 3758, 3782, 3793, 3819; and from the representation of 'Joseph' as the spiritual kingdom and so the spiritual man, dealt with in 3969, and therefore as the spiritual; for having its origin in the Lord, the spiritual is that which makes the spiritual man and also the spiritual kingdom what they are. By means of Jacob's sons by the servant-girls and by Leah, the sections prior to this have dealt with the reception and acknowledgement of general truths, and eventually with the joining of those truths to the interior man, and so have dealt with man's regeneration up to and including his becoming spiritual. 'Joseph' is that spiritual man. The present sections coming directly after them deal with the fruitfulness and the multiplication of truth and good, which are meant by the flock which Jacob obtained for himself by means of Laban's flock.

[2] Indeed after the joining of the interior man to the external man has taken place, that is, of the spiritual and the natural, fruitfulness of good and multiplication of truth take place, for that joining together of the two is the heavenly marriage with man. It is from this marriage that such fruitfulness and multiplication spring. This also is why 'Joseph' in the external sense means fruitfulness and multiplication, 3965, 3969, the expressions 'fruitfulness' being used in reference to good, and 'multiplication' to truth, 43, 55, 913, 983, 2846, 2847.
