557. Verse 9. (Revelation 9:9) And they had breastplates as iron breastplates, signifies the persuasions with which they gird themselves for combats, against which the truths of the rational-spiritual man prevail not. This is evident from the signification of "breastplates" (or coats of mail), as being defenses against evils and falsities in combats, but here defenses of evils and falsities against goods and truths, because this treats of those who are in the falsities of evil in opposition to truths. Here "breastplates" signify persuasions, because sensual men who are in the falsities of evil, who are here described, do not fight against truths from reason, for they do not see truths, but falsities only, and are therefore in the persuasion that falsities are truths, consequently they fight solely from the persuasion of falsity, and with them this persuasion is such that the truths brought forth by the spiritual-rational man are of no avail, for they are repelled as a sword is from a breastplate or coat of mail. So "breastplates as iron breastplates" signify persuasions against which truths are of no avail. That the persuasiveness with such is so infatuating and suffocating that the spiritual-rational is of no avail against it may be seen above (n. 544, 549, 556). Moreover, breastplates or coats of mail, cover that part of the body called the breast or thorax, and this signifies the spiritual affection of truth; also all affection is contained in the sound which comes forth from the breast with the speech. But those who are here signified by "locusts," who are such sensual men as are in falsities, have no other affection than that of the love of self, and because that affection is full of self-confidence and full of the persuasion that their falsity is truth, and because that affection is in the sound which comes forth from the breast with the speech, so the locusts appeared in "breastplates which were as iron breastplates." Moreover, "iron" signifies truth in ultimates, and likewise falsity there, and at the same time what is hard; and the persuasiveness that they have causes the falsity to be so hard that the truths opposed to it rebound, as if they were of no account or avail. Because the persuasion of sensual men who are in falsities from self-confidence is such, and with spirits is so powerful that it suffocates and extinguishes the rational of other spirits with whom they converse in the world of spirits, it is severely prohibited, and those who make use of it are sent among spirits where they are distressed even to swooning by other spirits by means of still stronger persuasions, and this until they desist.

[2] Because breastplates or coats of mail were in use in wars, and to put them on signified to gird oneself for war and thus to fight, therefore in the Word those who were girt for fighting are said to have put on coats of mail. Thus in Jeremiah:

Harness the horses, and go up, ye horsemen; and stand ye forth in helmets; furbish the spears, and put on the coats of mail (46 Jeremiah 46:4).

These words do not mean the combat of one army against another, but the combat of the spiritual-rational man against the natural man who, from knowledges [scientifica] falsely applied, fights against truths and goods. For this is said of the army of Pharaoh king of Egypt, whom the king of Babylon smote, and "Pharaoh king of Egypt" means such a natural man, and "the king of Babylon," near the Euphrates, means the spiritual-rational man, therefore "Harness the horses, go up, ye horsemen, and stand ye forth in helmets; furbish the spears, and put on the coats of mail," signifies such things as relate to the combat of the spiritual-rational man against the natural man who is in falsities; "horses" mean the things of the understanding, "chariots to which they were harnessed" the things of doctrine, "horsemen" the intelligent, "helmets" the things of reason, "spears" truths combating, and "coats of mail" force and strength in fighting and resisting. A "coat of mail" has this meaning because it girds the breast, and from the breast through the arms is all the strength in fighting and resisting.

[3] In the same:

Against Babylon let him bend, let him that bendeth bend his bow; against her he shall lift himself up in his coat of mail (Jeremiah 51:3).

Here, too, "coat of mail" stands for the power to fight and resist. In Isaiah:

He put on righteousness as a coat of mail, and the helmet of salvation upon His head (Isaiah 59:17).

This treats of the Lord, and of the subjugation of the hells by Him; and "righteousness as a coat of mail" signifies the zeal for rescuing the faithful from hell and the Divine love of saving the human race; and as it was from the zeal of Divine love and power therefrom that the Lord fought and conquered, so righteousness is called a "coat of mail;" while the "helmet of salvation" signifies Divine truth from Divine good, by means of which is salvation, for a "helmet" has a similar signification as the head, because it is worn on the head; that the "head" in reference to the Lord signifies Divine truth and Divine wisdom will be seen in what follows.

2762. The origin of 'a horse' meaning the understanding part of the mind lies nowhere else than in representatives in the next life. Frequently there, in the world of spirits, horses which display great variety are seen, and also people seated on horses. And whenever they are seen the understanding is meant by them. Such representatives are of constant occurrence among spirits. It is because the horse is a representative of the understanding that when horses are mentioned in the Word the spirits and angels present with man know instantaneously that it is the understanding which is being spoken of. It is also why, when spirits from some other planet who have been endowed with intelligence and wisdom are raised up from the world of spirits into heaven, horses shining as though they consisted of fire appear, which I also have seen when those people were carried up.

[2] This experience has made clear to me what is meant by the fiery chariot and the fiery horses which Elisha saw when Elijah went up with the whirlwind into heaven, and what also by Elisha's shout at that time,

My father, my father, the chariot of Israel, and its riders. 2 Kings 2:11-12, and by the same spoken by Joash king of Israel to Elisha when the latter was dying,

My father, my father, the chariot of Israel, and its riders. 2 Kings 13:14.

In the Lord's Divine mercy it will be shown elsewhere that Elijah and Elisha represented the Lord as to the Word. That is to say, it will there be shown that the doctrine of love and charity drawn from the Word is meant by 'the fiery chariot', and the doctrine of faith deriving from these by 'the fiery horses'. The doctrine of faith is the same as an understanding of the Word as to its inner content, which is the internal sense.

[3] As regards chariots and horses being seen in heaven among spirits and angels, this is evident not only from the fact that they were seen by the prophets, such as by Zechariah (1:8-10; 6:1-7) and by others, but also by Elisha's servant, of whom the following is said in the Book of Kings,

Jehovah opened the eyes of Elisha's servant, and he saw; and behold the mountain was full of horses, and there were fiery chariots surrounding Elisha. 2 Kings 6:17.

Furthermore, where the intelligent and wise dwell in the world of spirits, chariots and horses are constantly making their appearance, the reason being, as has been stated, that chariots and horses represent the things that belong to wisdom and intelligence. People who have been awakened after death and are entering the next life see represented to them a young man seated on a horse, who then dismounts. The meaning of this is that before they can enter heaven they have to be furnished with cognitions of good and truth - see Volume One, in 187, 188. The fact that chariots and horses meant those things was fully known in the Ancient Church, as becomes clear also from the Book of Job, a book of the Ancient Church, where these words occur,

God has made him forget wisdom and given him no share in intelligence. After raising himself on high he laughs at the horse and its rider. Job 39:17-19.

[4] The meaning of 'a horse' as the understanding spread from the Ancient Church to the wise in surrounding regions, and even into Greece. As a consequence of this, when describing the sun, which meant love, 2441, 2495, they placed the god of their wisdom and intelligence there in the sun, and gave him a chariot and four fiery horses. And when they described the god of the sea - the sea meaning knowledge in general, 28, 2120 - they gave horses to him also. And when they described the upsurge of knowledge from the understanding they portrayed it as a flying horse which with its hoof broke open a fountain where the virgins who were the branches of knowledge dwelt. And by the Trojan horse nothing else was meant than a device of their understanding for destroying city walls. Even today, when the understanding is being described, it is quite usual, drawing on the custom received from those people of old, to portray the understanding as a flying horse or Pegasus, and to portray learning as a fountain. Yet scarcely anyone knows that 'a horse' in the mystical sense means the understanding, and 'a fountain' truth, let alone that those images with a spiritual meaning spread to the gentiles from the Ancient Church.
