70. The feet are said to be "like unto burnished brass," because burnished brass is polished brass, shining from something fiery; and "brass" in the Word signifies natural good. Metals are equally significative with the rest in the Word. "Gold" in the Word signifies celestial good, which is inmost good; "silver" signifies the truth thereof, which is spiritual good: "brass" natural good which is outmost good, and "iron" the truth thereof, which is natural truth.

Metals have such significations from correspondence; for in heaven many things are seen shining as if from gold and silver, and also many things as if from brass and iron; and it is there known that by these the goods and truths mentioned above are signified. It was from this that the ancients, who had a knowledge of correspondences, named the ages according to these metals; calling the first age the "golden," because innocence, love, and wisdom therefrom then ruled; but the second "silver," because truth from that good, or spiritual good, and intelligence therefrom then ruled; the third age "brazen" or "copper," because mere natural good, which is justness and sincerity of moral life, then ruled; but the last age they called "iron," because mere truth without good then ruled, and when that rules, falsity also rules. All this was from the spiritual signification of these metals.

[2] From this it can be known what is signified by the image seen in a dream by Nebuchadnezzar:

The head of which was of gold, the breast and arms of silver, the belly and sides of brass, the legs of iron, and the feet partly of iron and partly of clay (Daniel 2:23, 33);

namely, the state of the church in respect to good and truth, from its first time to its last; its last time was when the Lord came into the world. When it is known that "gold" signifies celestial good, "silver" spiritual good, "brass" natural good, and "iron" natural truth, many arcana in the Word, where these metals are mentioned, can be understood. Thus what is signified by these words in Isaiah:

For brass I will bring gold, for iron I will bring silver, and for wood brass, and for stones iron; I will also make thy government peace, and thine exactors justice (Isaiah 60:17).

[3] But as the signification of "brass," as meaning natural good, is here treated of, I will cite only a few passages where "brass" is mentioned, as signifying that good. Thus in Moses:

Asher acceptable unto his brethren, and dipping his foot in oil. Thy shoe iron and brass, and as thy days thy fame (Deuteronomy 33:24-25).

"Asher," as one of the tribes, signifies the blessedness of life, and the delight of affections (See Arcana Coelestia 3938-3939, 6408); "to dip the foot in oil" signifies natural delight, "oil" is delight (See n. 9954), "foot" the natural (See just above, n. 69; "the shoe iron and brass" signifies the lowest natural from truth and good, "the shoe" is the lowest natural (See n. 1748, 1860, 6844), "iron" is its truth, and "brass" its good (as above). In the same:

Jehovah thy God will bring thee into a wealthy land; a land out of whose stones thou mayest hew out iron, and out of its mountains brass (Deuteronomy 8:7, 9).

In Jeremiah:

I will give thee unto this people for a fortified wall of brass, that they may fight against thee and not prevail against thee (Jeremiah 15:20).

And in Ezekiel:

Javan, Tubal, and Meshech, they were thy traffickers; with the soul of man and with vessels of brass they traded thy merchandise (Ezekiel 27:13).

In this chapter the traffickings of Tyre are treated of, by which are signified the knowledges of good and truth; by the names "Javan," "Tubal," and "Meshech," are signified such things as are of good and truth, of which knowledges treat; the "soul of man" is truth of life; "vessels of brass" are scientifics of natural good. (What is signified by "Tyre" may be seen in Arcana Coelestia 1201; what by "traffickings," n. 2967, 4453; what by "Tubal and Meshech," n. 1151; what by "Javan," n. 1152, 1153, 1155; what by the "soul of man," n. 2930, 9050, 9281; what by "vessels," n. 3068, 3079, 3316, 3318) In the same:

The feet of the cherubs sparkled like the appearance of polished brass (Ezekiel 1:7).

What "cherubs" and "feet" signify, see above n. 69.

[4] In the same:

I saw and behold there was a man, whose appearance was like the appearance of brass, and a line of flax was in his hand; and he was standing in the gate (Ezekiel 40:3).

It was because this angel measured the wall and the gates of the house of God, which signify the externals of the church, that his appearance was seen as the appearance of brass. He who knows that "brass" signifies the external of the church, which in itself is natural, can in some measure know why:

The altar of burnt-offering was overlaid with brass, and the grating about it was of brass, and the vessels of brass (Exodus 27:1-4);

as also why:

The great vessel, which was called the sea, with the twelve oxen under it, and the ten lavers with the bases, and also all the vessels of the tabernacle for the house of God, were made by Solomon of polished brass (1 Kings 7:43-47).

[5] He who knows what "brass" signifies may also enter into the arcanum why it was commanded that a serpent of brass be set up for the people to look at, of which it is thus written in Moses:

Jehovah sent serpents among the people, and they bit the people. And He said unto Moses, Make thee a serpent, and set it upon a standard, and it shall come to pass that everyone that is bitten, and looketh upon it, shall live. And Moses made a serpent of brass, and set it upon a standard; and it came to pass, that if a serpent had bitten any man, and he looked unto the serpent of brass, he lived (Numbers 21:6, 8-9).

That this "serpent" signified the Lord, He Himself teaches in John:

As Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up, that whosoever believeth in Him may not perish, but may have everlasting life (John 3:14-15).

By the "serpent" is signified that which is the ultimate of life with man, and is called the external sensual, which is the natural. Because this ultimate in the Lord was Divine, a serpent of brass was made among the sons of Israel, with whom all things were representative; and this signified that if they would look to the Divine Human of the Lord they would live again, that is, if they would believe in Him they would have eternal life, as the Lord Himself also teaches. (That to "see" is in the spiritual sense to believe, see above, n. 37, 68; and that the "serpent" is the external sensual, which is the ultimate of man's life, see Arcana Coelestia 195-197, 6398, 6949, 10313) That "brass" and "iron" in the Word also signify what is hard (as in Isaiah 48:4; Daniel 7:19 where), will be seen in what follows.

6971. 'And do not hear the voice of the former sign' means that if they did not obey what was declared by the Word, then instead of being spiritual and rational they would become people who were not spiritual or rational. This is clear from the meaning of 'hearing' as obeying, dealt with in 2542, 3869, 5017; from the meaning of 'the voice' as what is declared by the Word, dealt with below; and from the meaning of 'the former sign' as an indication that instead of being spiritual and rational they would become people who were not spiritual or rational. The truth of this may be seen from the meaning of 'the serpent' that was made out of Moses' rod when it was thrown onto the earth - the event to which 'the first sign' refers here - as a person who thinks on a sensory and bodily level, 6949, and so is not spiritual or rational. For a person who is sensory- and bodily-minded is not rational, and so is not spiritual either, because he thinks things that are false and desires those that are evil. One who behaves like this is not rational, still less spiritual, for an acceptance of and belief in what is true, together with a life of goodness, since these two come from the Divine, constitute true spirituality within rationality, whereas an acceptance of and belief in what is false, together with a life of evil, are the opposite. For the fact that wholly sensory- and bodily-minded people are like this, see 6844, 6845, 6948, 6949.

[2] Those people become wholly sensory- and bodily-minded who have first had a knowledge of things that belong to the spiritual world but after that have rejected them, and then have adopted fundamental ideas of falsity that are contrary to truths and focused their lives solely on worldly, bodily, and earthly values. They have consequently come to believe that life is meant to be filled with pleasures of every kind, saying, 'What more does a person have while he is alive? When we die, we die; as for the possibility of life after death, has anyone ever come back to talk about it? We have no knowledge of anything that will go on living when the life goes out of a person.' If anyone using rational arguments induces those people to give any thought to eternal life, they think that nothing worse will happen to them than to anyone else, and they immediately go back to living in the way they had done previously. With such people the passageway for the light of heaven to flow in is closed, and at the natural level of their minds the light of heaven is turned into thick darkness, while the light of the world there becomes brightness, 6907, a brightness that shines ever more brilliantly, the more that the light of heaven is darkened. This is why such people do not see the evil in their lives as anything other than goodness, or consequently the false ideas as anything other than true. Here then is the reason why a person becomes sensory- and bodily-minded. In short, once the way is opened for the light of heaven to flow in and then closed, a person is impelled to look downwards, and not upwards. This is done in keeping with Divine order so as to prevent truths once accepted and remaining in a person's inner self from being contaminated by falsities and thereby rendered profane.

[3] The same applies to gentiles who fall away from their religion, though their lot is better than that of people within the Church since what they possess are not truths from the Word, not genuine truths therefore but truths coupled with many misconceptions, which cannot be profaned in the way genuine ones can.

As regards the meaning of 'the voice' as that which is declared by the Word, it should be recognized that frequent use is made of the expression 'the voice'. It is also linked to other things that have nothing to do with a voice, such as the linking of it here to 'the sign' - 'If they do not hear the voice of the former sign they will believe the voice of the latter sign' - and also elsewhere, for example in Nahum,

The voice of the whip and the voice of the sound of the wheel. Nahum 3:2.

And in David,

The rivers have lifted up their voice, more than the voices of many mighty waters. Psalms 93:3-4.

[4] The fact that 'the voice' means a declaration, in the good sense a declaration by the Word, when it is called 'the voice of Jehovah', is clear in David,

The voice of Jehovah is powerful; the voice of Jehovah is glorious; the voice of Jehovah breaks the cedars; the voice of Jehovah flashes forth flames of fire; the voice of Jehovah causes the wilderness to shake; the voice of Jehovah causes the hinds to calve, and strips the forests bare. Psalms 29:3-5; Psalms 7-9.

And elsewhere in the same author,

. . . to Him who rides above the heavens of heavens of old. Behold, He will put forth His voice, a mighty voice. Psalms 68:33.

Here 'voice' stands for Divine Truth, and so for the Word and a declaration made by it. For what more is meant by 'voice', see 219; and for its use in reference to truth, 3563.
