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.

10. John, to the seven churches. (1:4) This symbolically means, to all who are in the Christian world where the Word exists and where through it the Lord is known, and who turn to the church.

The seven churches mean, not seven churches, but all who are constituents of the church in the Christian world. For numbers in the Word symbolize properties, and seven symbolizes all things or all people, and so also fullness and completeness, and it occurs in the Word where the subject is something holy, and in an opposite sense, something profane. Consequently this number involves holiness, and in an opposite sense, profanation.

Numbers symbolize properties, or rather they serve as a class of adjectives to substantives, assigning some attribute to their subjects, because a number in itself is a natural quantity. For natural things are measured by numbers, but spiritual things by properties and their states. Therefore someone who does not know the symbolism of numbers in the Word, and particularly in the book of Revelation, cannot know the many secrets that it contains.

Now, because seven symbolizes all things or all people, it is apparent that the seven churches mean all people in the Christian world where the Word exists and where through it the Lord is known. If these live according to the Lord's commandments in the Word, they form the real church.

[2] It is because of this that the Sabbath was instituted on the seventh day, and that the seventh year was called a sabbatical year, and the forty-ninth year the year of Jubilee, which symbolized everything holy in the church.

It is because of this, too, that a week in Daniel and elsewhere symbolizes an entire period from beginning to end and is predicated of the church.

Similar things are symbolized by seven hereafter, as for example, by the seven golden lampstands, in the midst of which was the Son of Man (Revelation 1:13); by the seven stars in His right hand (1:16, 20); by the seven spirits of God (1:4; 4:5); by the seven lamps of fire (4:5); by the seven angels to whom were given seven trumpets (8:2); by the seven angels having the seven last plagues (15:5-6); by the seven bowls full of the seven last plagues (16:1; 21:9); by the seven seals with which the book was sealed (5:1).

Likewise in the following places: That their hands should be filled for seven days (Exodus 29:35). That they should be sanctified for seven days (Exodus 29:37). That when they were inaugurated they should go in seven days, clothed in holy garments (Exodus 29:30). That for seven days they should not go out of the Tabernacle while being initiated into the priesthood (Leviticus 8:33, 35). That atonement should be made for the altar seven times on its horns (Leviticus 16:18-19), and also seven times toward the east (Leviticus 16:12-15). That the water of separation should be sprinkled seven times toward the Tabernacle (Numbers 19:4). That Passover should be celebrated for seven days and unleavened bread eaten for seven days (Exodus 12:1ff., Deuteronomy 16:4-7).

So, too, that the Jews should be punished sevenfold for their sins (Leviticus 26:18, 21, 24, 28), on which account David says, "Requite our neighbors sevenfold into their bosom" (Psalms 79:12). "Sevenfold" means fully.

[3] Also in these places:

The words of Jehovah are pure words, silver... in a furnace... purified seven times. (Psalms 12:6)

The hungry have ceased, until the barren has borne seven, while she who has many children has become feeble. (1 Samuel 2:5)

"The barren" is the church of the gentiles, who did not have the Word. "She who has many children" is the church of the Jews, who did have the Word. Similarly,

She will languish who has borne seven; she will breath out her soul. (Jeremiah 15:9)

Those who dwell in the cities of Israel will... set on fire and burn the weapons...; and they will make fires with them for seven years... ...they will bury Gog, and... for seven months... will be cleansing the land. (Ezekiel 39:9, 11-12)

(The unclean spirit) will take seven other spirits more wicked than himself... (Matthew 12:45)

Profanation is described there, and the seven spirits with which he would return symbolize all falsities of evil, thus a complete extinguishing of goodness and truth.

The seven heads of the dragon, and the seven jewels ¹ on its heads (Revelation 12:3), symbolize the profanation of all goodness and truth.

This makes apparent that "seven" involves holiness or profanation, and symbolizes completeness and fullness.
