257. Since in this prophetical book numbers are often mentioned, and no one can know the spiritual sense of the things contained therein unless it is known what the particular numbers signify (for all numbers in the Word, like all names, signify spiritual things), and since the number "seven" is often mentioned among others, I will here show that "seven" signifies all persons and all things, likewise fullness and totality; for that which signifies all persons and all things signifies also fullness and totality, for fullness and totality are predicated of the magnitude of a thing, and all persons and all things are predicated of multitude. That "seven" has such a signification can be seen from the following passages. In Ezekiel:

They that dwell in the cities of Israel shall set fire to and burn the arms, and the shield, and the buckler, with the bow and with the arrows, and the hand-staff, and the spear; and they shall make a fire with them seven years. And they shall bury Gog and all his multitude, and they shall cleanse the earth seven months (Ezekiel 39:9, 11-12).

Here the desolation of all things in the church is treated of: "those that dwell in the cities of Israel" signify all goods of truth; "to set fire" signifies to consume by evils. "The arms, the shield, the buckler, the bow, the arrows, the hand-staff, the spear," are all things pertaining to doctrine; "to make a fire with them seven years" means to consume them all and fully by evils. "Gog" signifies those who are in external worship and in no internal worship; "to bury them and cleanse the earth" means to destroy all such, and completely purge the church of them.

[2] In Jeremiah:

The widows shall be multiplied more than the sand of the seas, and I will bring to them upon the mother of the youths the waster at noonday. She that hath borne seven shall languish, she shall breathe out her soul (Jeremiah 15:8-9).

"The widows," that shall be multiplied, signify those who are in good and who long for truths, and in a contrary sense, as here, those who are in evil and desire falsities; "the mother of the youths" signifies the church; "the waster at noonday" signifies the vastation of that church, however much it may be in truths from the Word; "she that hath borne seven shall languish, she shall breathe out her soul," signifies that the church, to which all truths were given because the Word was given to it, is to perish; for "she that hath borne seven" signifies to whom all truths were given. This was particularly said of the Jews.

[3] Likewise in the first book of Samuel:

They that were hungry have ceased; the barren hath borne seven, and she that hath many children hath failed (1 Samuel 2:5).

"They that were hungry," who have ceased, are those who long for the truths and goods of the church; "the barren bearing seven" signifies those who are outside of the church, and are ignorant of truths, because they have not the Word, thus the Gentiles, to whom all things will be given; "she that hath many children failing" signifies those who have, from whom will be taken away. In David:

Render unto our neighbors sevenfold into their bosom (Psalms 79:12).

And in Moses:

That the Jews should be punished seven times for their sins (Leviticus 26:18, 21, 24, 28);

"seven times" here signifying fully.

[4] In Luke:

If thy brother sin against thee seven times in the day, and seven times in the day turn again to thee, saying, I repent, thou shalt forgive him (Luke 17:4).

"To forgive seven times, if he should turn again seven times," means to forgive as often as he turns, thus every time. But lest it should be understood to mean seven times, the Lord explained his meaning to Peter, who supposed seven times to be meant, in Matthew:

Peter said, Lord, how often shall my brother sin against me and I forgive him? Until seven times? Jesus saith unto him, I say not unto thee, until seven times, but until seventy times seven (Matthew 18:21-22).

"Seventy times seven" means always, without counting.

In David:

Seven times a day do I praise thee for the judgments of righteousness (Psalms 119:164).

"Seven times a day" means always, or at all times.

[5] In the same:

The sayings of Jehovah are pure sayings, as silver refined in a crucible purified seven times (Psalms 12:6).

"Silver" signifies truth from the Divine; "purified seven times" means wholly and fully pure.

[6] in Isaiah:

The light of the moon shall be as the light of the sun, and the light of the sun shall be sevenfold, as the light of seven days (Isaiah 30:26).

"The light of the sun" signifies Divine truth from Divine good; that "this light shall be sevenfold, as the light of seven days," signifies that Divine truth in heaven shall be without any falsity, thus altogether and fully pure.

[7] In Matthew:

The unclean spirit shall take seven other spirits more evil than himself, and shall dwell there (Matthew 12:45; Luke 11:26).

Here profanation is treated of, and "the seven unclean spirits" with which the unclean spirit would return, signify all the falsities of evil, thus a complete destruction of good and truth.

[8] The "seven times" that were to pass over the king of Babylon have a like meaning, in Daniel:

His heart shall be changed from man, and a beast's heart shall be given unto him, while seven times shall pass over him (Daniel 4:16, 25, 32).

"The king of Babylon" signifies those who profane the goods and truths of the Word; that "his heart should be changed from man, and a beast's heart be given him," means that nothing spiritual, which is the truly human, should remain, but instead there should be the diabolical; "the seven times which were to pass over him" signify profanation, which is the complete destruction of truth and good.

[9] Because "seven" and "seven times" signified all things and fullness, the following commands were given:

Seven days the hands [of Aaron and his sons] should be filled (Exodus 29:35).

Seven days [the altar] should be sanctified (Exodus 29:37).

Seven days Aaron should be clothed with the garments when he was to be initiated (Exodus 29:30).

For seven days Aaron and his sons were not to go out of the tabernacle when they were to initiated into the priesthood (Leviticus 8:33, 34).

Seven times was the altar to be sprinkled for expiation upon its horns (Leviticus 16:18, 19).

Seven times was the altar to be sanctified with oil (Leviticus 8:11).

Seven times was the blood to be sprinkled towards the veil (Leviticus 4:16, 17).

Seven times was the blood to be sprinkled with the fingers eastward, when Aaron went towards the mercy-seat (Leviticus 16:12-15).

Seven times was the water of separation to be sprinkled towards the tent (Numbers 19:4).

Seven times the blood was to be sprinkled in the cleansing of leprosy (Leviticus 14:7, 8, 27, 38, 51).

The lampstand was to have seven lamps (Exodus 25:32, 37; 37:18-25).

For seven days were the feasts to be kept (Exodus 34:18, Leviticus 23:4-9, 39-44; Deuteronomy 16:3, 4, 8).

For the seven days of the feast there was to be a burnt-offering of seven bullocks, and seven rams daily (Ezekiel 45:23).

Balaam built seven altars, and sacrificed seven oxen and seven rams (Numbers 23:1-7, 15-18, 29, 30).

They numbered seven weeks of years, seven times seven years, and then they were to cause the trumpet of the jubilee to be sounded in the seventh month (Leviticus 25:8, 9).

From the signification of the number "seven" it can be seen what is signified:

By the seven days of creation (Genesis 1);

Also by the fact that four thousand men were satisfied by seven loaves and that seven basketful remained (Matthew 15:34-38; Mark 8:5-9).

From this then it is evident what is signified in Revelation:

By the seven churches (Revelation 1:4, 11);

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 (Revelation 1:16, 20);

By the seven spirits of God (Revelation 3:1);

By the seven lamps of fire before the throne (Revelation 4:5);

By the book sealed with seven seals (Revelation 5:1);

By the seven angels to whom were given seven trumpets (Revelation 8:2);

By the seven thunders which uttered their voices (Revelation 10:3, 4);

By the seven angels having the seven last plagues (Revelation 16:1, 6);

And by the seven vials full of the seven last plagues (Revelation 16:1; 21:9);

and elsewhere in the Word, where "seven" is mentioned.

775. Having seven heads, signifies the knowledge [scientia] of the holy things of the Word which are falsified and adulterated. This is evident from the signification of "head," as being intelligence and wisdom, and in the contrary sense, insanity and folly (See above (Apocalypse Explained, n. 573, 577). And as intelligence and wisdom cannot be predicated of those who by reasonings from the natural man confirm the separation of faith and life, who are meant by "the beast coming up out of the sea," so "its head" signifies knowledge. It means the knowledge of the holy things of the Word, because there were "seven heads," and seven is predicated of things holy (See above, n. 257). The knowledge of the holy things of the Word is meant, because those meant by "the dragon" are not opposed to the Word; for they call the Word holy and Divine, because they collect from it the confirmations of their dogmas. But that they falsify and adulterate by these the holy things of the Word, of which they have knowledge, will be evident from what follows, and is evident in general from this, that those who separate faith from life cannot do otherwise, since such a separation is contrary to each and all things of the Word. For in all things of the Word and in every particular of it there is a marriage of good and truth, as is manifestly evident from the spiritual sense of the Word. This is why there are in so many passages two expressions that appear like repetitions of the same thing, but still one of them has reference to good and the other to truth; thus the two make as it were a marriage, which is called the Divine marriage, the celestial marriage, and the spiritual marriage, which regarded in itself is the marriage of good and truth. (Respecting this marriage see above, n. 238, 288, 484, 660) There must be a like marriage of faith and love, or of faith and good works; for faith pertains to truth, and truth to faith; and love pertains to good, and good to love. From this it is clear that those who separate faith from its life, or what is the same, from love, cannot do otherwise than falsify the Word, because they explain the sense of its letter in opposition to the marriage of good and truth which is in each and every thing of the Word.

[2] It has been said that the "head" signifies wisdom and intelligence, and that with those who are not in wisdom and intelligence it signifies knowledge [scientia]; therefore with those who falsify and pervert the Word it signifies insanity and folly, as above n. 715, where the signification of "the seven heads of the dragon" was explained; so "the head of this beast" has a similar signification, since this beast means the dragon in reference to reasonings from the natural man confirming the separation of faith from the life. The "head" signifies wisdom, intelligence, and the knowledge of truths, and in the contrary sense folly, insanity, and the knowledge of falsities, because these have their seat in the head, and are there in their beginnings. This is clearly evident from the fact that the origins of all fibers are in the head, and from it they proceed to all the organs of sense and motion belonging to the face and the whole body; and there, too, are substances in infinite number that look like little spheres and are called by anatomists the cortical and cineritious substances; and from these go forth small fibers, the first of which are undiscernible; afterwards these are bundled together, and make up the medullary substance of the whole cerebrum, cerebellum, and medulla oblongata. From this medullary substance discernible fibers extend, and these when conjoined are called nerves. By these the cerebrum, the cerebellum, and the spinal marrow form the entire body and each and all things pertaining to it; and from this it comes that each and all things of the body are ruled by the brains.

[3] From this it can be seen that the brains are the seat of the understanding and the will, which are called with one term, mind, and in consequence, of intelligence and wisdom, and that these are there in their first principles; also that the organs that are formed to receive sensations and to produce motions are derivations therefrom, precisely like streams from their fountains, or derivatives from their beginnings, or composite things from their substances; and these derivations are such that the brains are everywhere present, almost as the sun is present by its light and heat in each and all things of the earth. From this it follows that the whole body, and each and all things of it, are forms that are under the observation, auspices, and obedience, of the mind, which is in the brain; thus these forms are so constructed after the mind's direction that any part in which the mind is not present, or to which it does not communicate its life, is no part of man's life. From this it can be seen that when the mind is in its thought, which pertains to the understanding, and in its affection, which pertains to the will, it has an extension into every particular of the whole body, and there, by means of its forms, it spreads itself out as the thoughts and affections of the angels do into the societies of the universal heaven. The like is true here, since all things of the human body correspond to all things of heaven; consequently the form of the whole heaven before the Lord is the human form. (This is treated of at length in the Arcana Coelestia and in the work on Heaven and Hell.)

[4] This has been said to make known why the "head" signifies wisdom and intelligence, as also in the contrary sense folly and insanity. For such as man is in his beginnings such is he in the whole, for the body with each and every part of it is a derivation, as has just been said. If, therefore, the mind is in the belief of falsity and in the love of evil, its entire body, that is, the entire man, is in a like state. This is also clearly evident when man becomes a spirit, whether good or evil; then his whole spiritual body, from head to foot, is wholly such as his mind is. If the mind is heavenly, the whole spirit, even as to its body, is heavenly. If the mind is infernal, the whole spirit, even as to its body, is infernal; and in consequence such a spirit appears in a direful form like a devil, while the former spirit appears in a beautiful form like an angel of heaven. But on this more will be said elsewhere.
