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.

1832. 'But the birds he did not cut apart' means that no such parallelism and correspondence existed in the case of spiritual things. This is clear from the meaning of 'birds' as that which is spiritual, dealt with just above in verse 9, and from the fact that he did not part the birds down the middle, which consequently means that no such parallelism and correspondence existed in their case. By spiritual things, as has often been stated already, are meant all those things that constitute faith, consequently all those things which are matters of doctrine, as these are called matters of faith even though in fact they are not so until they have been joined to charity. Between these and the Lord no parallelism and correspondence exists, for they are not such as flow in through an internal dictate and through conscience - as matters of love and charity do - but such as flow in through the reception of teaching and so through hearing, thus not from what is more internal, but from that which is more external; and in this way they form in man their vessels or recipients.

[2] The majority of these have the appearance of being truths but in fact they are not so - like those things which belong to the literal sense of the Word, being also representatives of truth, and meaningful signs of truth, and so not in themselves truths. Some are even falsities, which nevertheless are able to serve as vessels and recipients. With the Lord however only those exist which are wholly and essentially truths, and therefore no parallelism or correspondence exists involving those apparent truths. Yet they may be rendered suitable to serve celestial things - which are matters of love and charity - as vessels. These apparent truths are what constitute the cloud in the understanding part of the mind, dealt with already, into which the Lord infuses charity and so forms conscience.

[3] Take, for example, people who keep to the sense of the letter of the Word and imagine that it is the Lord who brings on temptation, that it is He who at such times tortures a person's conscience, and who imagine that because He permits evil He is the author of evil, that He thrusts the wicked down into hell, and similar ideas. These are not truths, but apparent truths. And because they are not in themselves truths there is no parallelism and correspondence. Nevertheless the Lord leaves these things in man as they are and in a remarkable fashion adapts them by means of charity so that they may serve as vessels for celestial things. The same applies as well to the worship, the teachings, the practices, even the idols, of honest gentiles. In the same way the Lord leaves these things as they are, yet adapts them by means of charity so that they too may serve as vessels. The same was true of so many of the forms of ritual in the Ancient Church, and subsequently in the Jewish Church. In themselves they were nothing more than religious observances that contained no truth in them and which were tolerated and permitted, even prescribed, because they had been held sacred by parents, and so had been implanted in and impressed upon their minds as truths since they were children.

[4] These and other such things are what are meant by the statement that the birds were not divided. For the things that are once implanted in a person's beliefs and are held sacred, provided they are not contrary to Divine order, are left by the Lord as they are; and although no parallelism or correspondence exists He nevertheless adapts them. The same things were also meant in the sacrifices of the Jewish Church by the birds not being divided, for to divide is to set one part opposite the other so that they exactly correspond. But because those things to which reference has been made are not exactly correspondent, they are in the next life blotted out in the case of those who allow themselves to be taught, and truths themselves are implanted in their affections for good. For the sake of this representation and meaning, birds in the Jewish Church were not divided, as is clear in Moses,

If his gift to Jehovah is a burnt offering of a bird, he is to bring a gift of turtle doves or of young pigeons; he will tear it with its wings, he is not to divide it. Leviticus 1:14, 17.

Likewise in sacrifices for sin, Leviticus 5:7-8.
