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.

6112. 'And Joseph gathered up all the silver' means all factual knowledge that held truth in it and was appropriate. This is clear from the meaning of 'gathering up' as bringing together into a single whole; from the representation of 'Joseph' as the internal celestial, often dealt with already; and from the meaning of 'silver' as truth, dealt with in '551, 2954, 5658, but in this case factual knowledge that holds truth in it and is appropriate, for this silver existed, as stated in the words that immediately follow, in the land of Egypt and in the land of Canaan. All this shows that 'Joseph gathered up all the silver' means that the internal celestial brought together into a single whole all factual knowledge that held truth in it and that was appropriate. Factual knowledge is said to hold truth in it and to be appropriate when there are no illusions to darken it, for as long as these cannot be dispelled, factual knowledge is rendered inappropriate. The same is true of factual knowledge which has not become perverted through applications of it to falsities and to evils by others or by oneself, for once imprinted on factual knowledge such falsities and evils remain. Factual knowledge therefore which does not languish under these defects is factual knowledge that holds truth in it and is appropriate.
