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.

5268. 'And the seven thin and bad cows coming up after them are seven years' means a state when falsity attacking the interior natural is multiplied. This is clear from the meaning of 'cows' in the genuine sense as truths within the interior natural, dealt with in 5198, 5265, but in the contrary sense as falsities there, dealt with in 5202, so that the former are called 'good cows', but the latter 'thin and bad'; from the meaning of 'coming up' as an advance made towards things that are interior, dealt with in 5202; and from the meaning of 'years' as states, dealt with just above in 5265. Even as 'seven' means that which is holy, so in the contrary sense it means that which is unholy. For most things in the Word have a contrary meaning as well, the reason for this being that when the selfsame things as come into being in heaven pass downwards in the direction of hell, they are converted into things of an opposite nature and become in actual fact their opposites. Consequently things that are holy, meant by 'seven', are made in that place into those that are unholy.

[2] Let references to the number seven found solely in the Book of Revelation serve to prove that 'seven' is used to mean both holy things and unholy ones. The following are places where holy things are meant,

John to the seven Churches: Grace and peace from Him who is and who was and who is to come, and from the seven spirits who are before His throne. Revelation 1:4.

These things says He who has the seven spirits and the seven stars. Revelation 3:1.

From the throne there were coming seven lamps of fire burning before the throne, which are the seven spirits of God. Revelation 4:5.

I saw on the right hand of Him sitting on the throne a book written within and on the back, sealed with seven seals. Revelation 5:1.

I looked, and behold, in the midst of the throne, a Lamb standing as though it had been slain, having seven horns and seven eyes, which are the seven spirits of God sent out into all the earth. Revelation 5:6.

To the seven angels were given seven trumpets. Revelation 8:1.

In the days of the voice of the seventh angel the mystery of God was to be fulfilled. Revelation 10:7.

Out of the temple came the seven angels having the seven plagues, clothed in linen, white and splendid, and girded around their breasts with golden girdles. Then one of the four living creatures gave to the seven angels seven golden bowls. Revelation 15:6-7.

[3] The fact that 'seven' in the contrary sense means things that are unholy is evident from the following places, also in the Book of Revelation,

Behold, a great fiery-red dragon having seven heads and ten horns, and on his heads seven jewels. Revelation 12:3.

I saw a beast coming up out of the sea, which had seven heads and ten horns, and on its horns ten jewels, but on its heads a blasphemous name. Revelation 13:1.

I saw a woman sitting on a scarlet beast, full of blasphemous names; and it had seven heads and ten horns. Here is the understanding of this - if anyone has the wisdom: The seven heads are seven mountains on which the woman is seated; and they are seven kings. The beast which was, and is not, he is the eighth king, and is of the seven, and is going away into perdition. Revelation 17:3, 7, 9-11.
