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.

3373. 'And to your seed' means truth. This is clear from the meaning of 'seed' as truth, dealt with in 29, 255, 1025, 1447, 1610, 1940, 2848, 3310, and so truth from the Lord's Divine, which is 'your seed'. Those who understand the Word solely according to the sense of the letter can know no more than this, that 'seed' means descendants - here Isaac's descendants through Esau and Jacob, primarily through Jacob since the Word existed among that nation and so many of its historical descriptions have to do with them. But in the internal sense 'seed' is not used to mean any descendants from Isaac but all who are the Lord's 'sons', and so who are 'the sons of His kingdom', or what amounts to the same, those in whom good and truth which come from the Lord are present. And as these constitute 'the seed' it follows that good and truth themselves from the Lord are 'the seed', for these are what make people His 'sons'. This is also the reason why truths themselves which come from the Lord are called 'the sons of the kingdom' in Matthew,

He who sows the good seed is the Son of Man, the field is the world, the seed are the sons of the kingdom. Matthew 13:37-38.

And for this reason also 'sons' generally means truths, 489, 491, 533, 1147, 2623.

[2] Anyone who thinks rather more deeply or inwardly may recognize that the seed of Abraham, Isaac, and Jacob, mentioned so many times, and spoken of so many times as those who were to be blessed, and more so than all nations and peoples in all the world, cannot in the Divine Word mean the descendants of those three. For among all nations they least of all were moved by the good that flows from love to the Lord and from charity towards the neighbour. Nor indeed did any truth of faith exist with them. Who the Lord is, what His kingdom is, and so what heaven is and what the life after death, they did not know at all. They did not know these things because for one thing they did not wish to know and for another because if they had come to know about them they would have denied them completely in their hearts and so would have profaned interior goods and truths, as they did exterior by becoming on so many occasions open idolaters. This is the reason why any interior truths are rarely visible in the literal sense of the Old Testament Word. Because the nature of those people was such, the Lord therefore said about them, quoting Isaiah,

He has blinded their eyes and hardened their heart, lest they see with their eyes and understand with their heart, and are converted and I heal them. John 12:40.

What He said about them when they declared they were 'the seed of Abraham',

They said, We are the seed of Abraham. Our father is Abraham. Jesus said to them, If you were Abraham's sons, you would do the works of Abraham. You are from your father the devil, and the desires of your father you will to do. John 8:33, 39, 44.

Here also 'Abraham' is used to mean the Lord, as in every other instance in the Word. The Lord explicitly states that they were not His seed or sons but came from the devil. From this it is quite evident that 'the seed of Abraham, Isaac, and Jacob' in both the historical part and the prophetical part of the Word is in no way used to mean such descendants, for the Word is Divine in every detail Instead it means all who constitute 'the Lord's seed', that is, those with whom the good and truth of faith in Him are present. The fact that heavenly seed, that is, all good and truth, comes from the Lord alone, see 1438, 1614, 2016, 2803, 2882, 2883, 2891, 2892, 2904, 3195.
