176. Verse 27.And He shall rule them with an iron rod, signifies that He is about to chastise evils by means of truths that are in the natural man. This is evident from the signification of "ruling," as being to chastise, for it is added that "He would shiver them as pottery vessels," and the evils which are signified are chastised by means of truths. It is evident also from the signification of "an iron rod," as being truths that are in the natural man; a "rod" or "staff" signifies the power by which chastisement is effected; and "iron" truths in the natural man which chastise. (That a "rod" or "staff" is power, see Arcana Coelestia, n. 4013, 4015, 4876, 4936, 6947, 7011, 7026, 7568, 7572; that it is for this reason that kings have a scepter, which is a short staff, n. 4581, 4876.)

"Iron" signifies truths in the natural man, because metals, as well as the other things of the earth, by correspondence signify things spiritual and celestial, all of which have reference to truths and goods. "Gold" signifies the good of the internal man; "silver" its truth; "copper" or "brass" the good of the external or natural man; "iron" its truth. For this reason the ages were called by the ancients after the names of the metals, namely, Golden, Silver, Copper, and Iron; the Golden Age from the most ancient men, who lived in the good of love; the Silver Age from the ancients after them who lived in truths from that good; the Copper Age from their posterity who were in external or natural good; the Iron Age from the posterity of these who were in natural truth alone without good. Natural truth is truth in the memory, not in the life; truth of life is good. (But more about this correspondence in the work on Heaven and Hell, n. 104, 115.)

[2] The successive states of the church, even until the coming of the Lord, are meant by the "gold," the "silver," the "brass," and the "iron," of which the statue seen by Nebuchadnezzar in a dream was composed, which is thus described in Daniel:

His head was good gold, his breast and his arms silver, his belly and his thighs brass, his legs iron, his feet part iron and part clay. A stone was cut out of the rock, and it smote the image upon his feet that were iron and clay, and brake them to pieces. Whereas thou sawest the feet partly of potter's clay and partly of iron, it signifies that the kingdom shall be divided; the kingdom shall be partly strong, and partly broken. Whereas thou sawest the iron mixed with miry clay, they shall mingle themselves by the seed of man; but they shall not cleave one to another, even as iron doth not mingle with clay (Daniel 2:32-34, 41-43).

By "the head which was good gold," the first state of the church is meant, when men were in the good of love to the Lord; by "the breast and arms which were silver," the second state of the church is meant, when they were in truths from that good; by "the belly and thighs which were of brass," the following third state of the church, when they were no longer in spiritual good but in natural good, for "brass" signifies natural good; by "the legs which were of iron," the fourth state of the church is meant, when natural good was no more, but truth only; but by "the feet which were of iron and clay," the last state of the church is meant when there are both truth and falsity, truth in the Word and falsity in doctrine; when the truths of the Word are falsified, and doctrine is drawn from truths falsified, the state of the church is "partly iron and partly clay," thus the kingdom is "partly strong and partly broken." "The kingdom" here is the church; it is therefore called also "the kingdom of God." That truths are thus mixed with falsities, but still they do not cohere, is meant by these words, "Whereas thou sawest the iron mixed with miry clay, they shall mingle themselves by the seed of man; but they shall not cleave one to another, even as iron doth not mingle with clay." "The seed of man" is Divine truth, which is in the Word. (That this is signified by "seed," see Arcana Coelestia 3038, 3373, 10248, 10249; that "man" signifies the Lord, from whom is the Word, and also signifies the church, see n. 768, 4287, 7424, 7523, 8547, 9276.) That "potter's clay" signifies the falsities that are in the natural man, will be seen in the following article n. 177. By "the stone cut of the rock," which "smote the image upon his feet," the Lord by means of Divine truth is meant, and the destruction of falsities not cohering with truths from the Word. (That a "stone" is truth, and that "the stone of Israel" is the Lord in respect to Divine truth, see Arcana Coelestia 643[1-4], 1298, 3720, 6426, 8609, 10376; that "rock" likewise signifies the Lord, 8581, 10580, and in the small work on The Last Judgement, n. 57.) Because "iron" signifies truths in the natural man, "the feet of the statue" were seen to be "of iron," for "feet" signify the natural (See Arcana Coelestia 2162, 3147, 3761, 3986, 4280, 4938-4952).

[3] Like things are signified by "gold," "silver," "brass," and "iron," in these words in Isaiah:

For brass I will bring gold, for iron I will bring silver, for woods brass, and for stones iron (Isaiah 60:17).

"To bring gold for brass" means celestial good for natural good; "silver for iron" means celestial truth for natural truth; "brass for woods, and iron for stones," means natural good and truth in great abundance like that of woods and stones. Here the state of the celestial church is treated of. (That "iron" signifies truth in the natural man, see Arcana Coelestia 425, 426.)

[4] These passages are cited that it may be known what is meant by the "iron rod," namely, the power whereby the Lord chastises the evils and disperses the falsities that are in the natural man; for a "rod" or "staff" signifies power (as was said above), and "iron" signifies truths in the natural man. The Lord chastises evils and disperses falsities by means of truths in the natural man, because all evils and the falsities therefrom have their seat in the natural man, and none in the spiritual or internal man. The internal man does not receive evils and falsities, but is closed against them. And as all evils and falsities have their seat in the natural man, they must needs be chastised and dispersed by means of such things as are there, which are truths in the natural man. Truths in the natural man are knowledges and cognitions, from which man can think, reason, and conclude naturally respecting the truths and goods of the church, and the falsities and evils which are opposed to these, and can consequently be in some natural illustration when he reads the Word. For the Word in the letter is not understood without illustration; and illustration is either spiritual or natural. Spiritual illustration is only with those who are spiritual; and the spiritual are those that are of the good of love and charity and in truths therefrom; while mere natural illustration is with those who are natural (See in the work on Heaven and Hell 153, 425, 455; and above, n. 140. Moreover, those who are spiritual have, whilst they live in the world, illustration in the natural; but this springs from illustration in the spiritual; for with them the Lord flows in through the spiritual or internal man into the natural or external, and thus illustrates it, from which enlightenment man can see what is true and good, and what is false and evil, and when he sees that, the Lord scatters the evils and the falsities that are in the natural man, by means of the truths and goods that are also there and that make one with the goods and truths in the spiritual or internal man (See in The Doctrine of the New Jerusalem, on sciences and knowledges, what they effect, n. 51, and on Influx, n. 277, 278).

[5] From this it can now be seen what is signified by "the iron rod," with which the Lord is to rule the nations, that is, chastise the evils that are in the natural man. These things are said to the angel of this church, because in what is written to this angel the internal and external man and their conjunction are treated of; for when the internal and the external or the spiritual and the natural are conjoined, the Lord chastises the evils and falsities that are in the natural man, and this by means of the knowledges of truth and good. But with those with whom the internal and external man are not conjoined, evils and falsities cannot be chastised and scattered, since they receive nothing from heaven through the spiritual man, but all things they receive are from the world; and these their rational favors, and supplies confirmations. Things similar to those here signified by "the iron rod" are also signified in the following passages.

In David:

Thou shalt bruise [the nations] with an iron scepter; as a potter's vessel Thou shalt dash them in pieces (Ps. 2:9).

In Isaiah:

He shall smite the land with the rod of His mouth, and with the breath of His lips shall He slay the wicked (Isa. 11:4).

In Revelation:

The woman brought forth a male, a son, who is to rule all nations with an iron rod (Rev. 12:5).

Out of the mouth of the One sitting on the white horse went forth a sharp sword, that with it He should smite the nations; for He shall rule them with an iron rod (Rev. 19:15).

In Micah:

Arise, O daughter of Zion; for I will make thine horn iron, and I will make thy hoofs brass, that thou mayest beat in pieces many peoples (Micah 4:13).

The "daughter of Zion" is the celestial church; "horn" is power in the natural man; "hoofs" are the ultimates there, called sensual scientifics; hence it is evident what is signified by "making the horn iron, and the hoofs brass." (That the "daughter of Zion" is the celestial church, see Arcana Coelestia, n. 2362, 9055; that "horn" is the power of truth from good in the natural man, n. 2832[1-15], 9081, 9719, 9720, 9721, 10182, 10186; and that "hoofs" are the knowledges of the sensual man, which are truths in the ultimate of order, n. 7729.)
