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.

43. Truths in the Word’s literal sense are meant by the foundations of the wall of the New Jerusalem in Revelation 21. This follows from the fact that the New Jerusalem means a new church in respect to doctrine, as shown in The Doctrine of the New Jerusalem Regarding the Lord 62, 63. Its wall, therefore, and the foundations of the wall, can only mean the outer component of the Word, which is its literal sense; for that is the origin of doctrine, and through doctrine, the church. Moreover, doctrine is like a wall which, with its foundations, surrounds a city and protects it.

Respecting the wall of the New Jerusalem and its foundations, we read in the book of Revelation the following:

(The angel) measured (the city Jerusalem’s) wall, a hundred and forty-four cubits, (which was) the measure of a person, that is, of an angel. (Revelation 21:17)

And the wall had twelve foundations, “adorned with all kinds of precious stones”:

The first foundation was jasper, the second sapphire, the third chalcedony, the fourth emerald, the fifth sardonyx, the sixth sardius, the seventh chrysolite, the eighth beryl, the ninth topaz, the tenth chrysoprase, the eleventh jacinth, and the twelfth amethyst. (Revelation 21:19-20)

The number 144 symbolizes all the truths and goods of the church drawn from the Word’s literal sense, and so does the number 12. A person symbolizes intelligence; an angel, Divine truth from which that intelligence originates; measuring, their character; the wall and its foundations, the Word’s literal sense; and precious stones, the Word’s truths and goods in their sequence, from which doctrine originates, and through doctrine, the church.
