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.

5576. 'And the famine grew more serious' means the desolation resulting from the dearth of spiritual things. This is clear from the meaning of 'the famine' as an absence of cognitions of goodness and truth, dealt with in 3364, 5277, 5279, 5181, 5300, and the consequent desolation, 5360, 5376, 5415. And because desolation can arise from a shortage and consequent dearth of spiritual realities, 'the famine' has this meaning too. A famine in the spiritual world or heaven is not a hunger for [bodily] food, for angels do not feed on material food, which is the food for that body which a person carries around in the world. Rather it is a hunger for the kind of food that nourishes their minds, and this, which is called spiritual food, consists in understanding what is true and in having a wise discernment of what is good. And what is amazing, angels are nourished with this food.

[2] This has been made clear to me by the fact that after young children, who have died as young children, have been furnished in heaven with truths that are the constituents of intelligence and with forms of good that are the essence of wisdom, they no longer look like young children but adults, increasingly so as goodness and truth increase with them. The nourishment of angels by spiritual food has also been made clear to me by the fact that they have a constant desire for those things that are the constituents of intelligence and wisdom. At their eveningtime, that is, when they pass through a state in which they lack what they desire, that state compared with other states holds no happiness for them. In that state there is nothing that they hunger and long for more than a new dawning of morning light upon them and their return to the life filled with happiness that comes with intelligence and wisdom.

[3] It may also be seen by anyone who stops to reflect on the matter that understanding what is true and desiring what is good constitute spiritual food. If someone who is enjoying material food that serves to nourish the body is at the same time in a cheerful state of mind and is engaged in conversation about the kinds of things that accord with that state of mind, the material food for the body becomes all the more nourishing. This is an indication of the existence of a correspondence between spiritual food, which feeds the soul, and material food, which feeds the body. The same is clear in addition from the experience of someone who has the desire to furnish his mind with ideas that constitute knowledge, intelligence, and wisdom. If he is denied these he begins to feel sad and distressed, and like somebody in time of famine he has the desire to return to his spiritual food and so to the nourishment of his soul.

[4] It may also be seen from the Word that spiritual food is what nourishes the soul in the way material food nourishes the body, as in Moses,

Man does not live by bread only, but man lives by every utterance of the mouth of Jehovah. Deuteronomy 8:3; Matthew 4:4.

In general 'utterance of the mouth of Jehovah' is the Divine Truth which goes forth from the Lord, and so is every truth contained in wisdom; specifically it is the Word, the foundation and source of ideas constituting wisdom. And in John,

Do not labour for the food which perishes, but for the food which endures to eternal life, which the Son of Man will give you. John 6:17.

This 'food' is clearly the truth that is contained in wisdom and that goes forth from the Lord.

[5] From this one may also recognize what is meant by these words of the Lord recorded in the same chapter,

My flesh is truly food, and My blood truly is drink. John 6:55.

That is to say, 'the Lord's flesh' is Divine Good, 3813, and 'His blood' Divine Truth, 4735. For now that the Lord has made His Human completely Divine, His 'flesh' is nothing else than Divine Good, and His 'blood' nothing else than Divine Truth. One has to understand that in the Divine there is nothing material; therefore in the highest sense, that is, where it has reference to the Lord, 'food' is the Good of Divine Love directed towards the salvation of the human race. This food is also the kind that is meant by the Lord's words in John,

Jesus said to the disciples, I have food to eat of which you do not know. My food is to do the will of Him who sent Me, and to finish His work. John 4:32, 34.

'Doing the will of Him who sent Me, and finishing His work' is saving the human race; and the Divine attribute which motivates this is Divine Love.

From all this one may now see what is meant in the spiritual sense by 'the famine'.
