70. The reason why the feet are said to be like unto fine brass is, that by fine brass is meant brass polished and shining, like something fiery; and brass in the Word signifies natural good. Metals, like all other things in the Word, are significative. Gold in the Word signifies celestial good, which is inmost good; silver signifies its truth, which is spiritual good; brass natural good, which is ultimate good, and iron its truth, which is natural truth. That such things are signified by metals, is from correspondence; for many things are seen in heaven shining like gold and silver, and also many things shining like brass and iron. And it is there known, that by those things are signified the above-mentioned kinds of good and truth; this is why the ancients, who were in the knowledge of correspondences, named the ages after those metals. The first age they called the golden age, because innocence, love and wisdom therefrom, then reigned; but the second age they called the silver age, because truth from that good, or spiritual good, and intelligence therefrom, then reigned; the third age they called the brazen, or copper, age, because only natural good, which is what is just and sincere pertaining to moral life, then reigned; but the last age they called the iron age, because only truth without good then reigned, and when that reigns, then also falsity reigns. The reason why the ages were thus distinguished, was from the spiritual signification of those metals.

[2] From these considerations it is evident what is signified by the statue of Nebuchadnezzar, seen in his dream,

"whose head was of gold, the chest and arms of silver, the belly and thighs of brass, the legs of iron, and the feet partly of iron and partly of clay" (Dan. 2:32, 33).

The state of the church from its first time to its last as to good and truth, is here signified; 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 those metals are mentioned can be known. For example, 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" (60:17).

[3] But as the signification of brass is what is here treated of, as being natural good, it is necessary only to adduce a few passages where brass is mentioned and signifies that good. Thus in Moses:

"Asher acceptable to his brethren, and dipping his foot in oil; iron and brass thy shoe, and as thy day, thy fame" (Deuteronomy 33:24, 25).

Asher, as one of the tribes, signifies the happiness of life, and the delight of the affections (see Arcana Coelestia 3938, 3939, 6408); to dip the foot in oil signifies natural delight (that oil denotes delight, see n. 9954, and that the foot denotes the Natural, see above, n. 69); the shoe being iron and brass signifies the lowest Natural derived from truth and good, shoe denoting the lowest Natural (see n. 1748, 1860, 6844); iron is its truth, and brass its good, as above. Again,

"Jehovah thy God will bring thee into a rich land; a land out of whose stones thou shalt cut iron, and out of whose mountains brass" (Deuteronomy 8:7, 9).

And in Jeremiah:

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

And in Ezekiel:

"Javan, Tubal, and Mesech, they were thy merchants; with the soul of man and vessels of brass they gave thy merchandise" (27:13).

In this chapter the merchandises of Tyre are treated of, by which are signified the knowledges (cognitiones) of good and truth. By the names Javan, Tubal, and Mesech, are signified those things that pertain to good and truth, to which the knowledges relate; the soul of man denotes the truth of life; vessels of brass denote scientifics of natural good.

[4] (What is signified by Tyre, may be seen, Arcana Coelestia 1201; what by merchandises, n. 2967, 4453; what by Tubal and Mesech, 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.)

Again, in the same prophet:

The feet of the cherubs "shone like the appearance of polished brass" (1:7).

(What the cherubs and the feet signify, may be seen above, n. 69.) And in the same prophet:

"I saw, and, lo, a man, whose appearance was like the appearance of brass, and a thread of flax in his hands; he stood in the gate" (40:3).

Because the angel here mentioned measured the wall and the gates of the house of God, which signify the externals of the church, his appearance was seen to be the appearance of brass.

He who knows that brass signifies the external of the church, which in itself is natural, may in some measure understand why the altar of burnt-offering was overlaid with brass, and the gate round it was of brass, and the vessels of brass (Exodus 27:1-4), 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). He who knows what brass signifies, can also enter into the arcanum why a serpent of brass was commanded to be set up for the people to look at, concerning which it is thus written in Moses:

"Jehovah sent serpents among the people, which bit the people. And he said unto Moses, Make thee a serpent, and set it upon a pole; and it shall come to pass that every one that is bitten, when he hath looked upon it, shall live. And Moses made a serpent of brass, and set it upon a pole, and it came to pass, that when a serpent had bitten any man, and he looked upon the serpent of brass, he lived" (Numbers 21:6, 8, 9).

That the Lord was signified by that serpent, 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 should not perish, but have everlasting life" (3:14, 15).

By the serpent is signified the ultimate of life in man, which is called the external Sensual, which is natural. To represent this ultimate, which in the Lord was Divine, among the sons of Israel, with whom all things were representative, a serpent of brass was made; and the signification was, that, if they looked to the Divine Human of the Lord, they would revive, that is, if they believed in Him, they should have eternal life, as the Lord himself also teaches. (That to see in the spiritual sense is to believe, may be seen above, n. 37, 68; and that a serpent denotes the external Sensual, which is the ultimate of the life of man, 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; Dan. 7:19; and other places, will be seen in the following pages.

5126. 'And you will put Pharaoh's cup into his hand' means in order that they might consequently serve the interior natural. This is clear from the meaning of 'putting the cup to drink' as making one's own, dealt with above in 5120, besides the obvious meaning of serving; and from the representation of 'Pharaoh' as the interior natural, dealt with in 5080, 5095, 5118. For there is an interior natural and there is an exterior natural, the exterior natural being made up of impressions which enter in directly from the world by way of the senses into the natural mind, that is to say, they enter the memory belonging to that mind and therefore enter the place where mental images are formed, see 5118.

[2] So that people can know what the exterior natural and what the interior natural are like, which make up the exterior man, and from this can know what the rational is which makes up the interior man, a brief reference to them must be made here. From infancy to childhood a person relies solely on his senses, for during those years he is receiving, through his bodily senses, nothing but earthly, bodily, and worldly impressions, which during those years are also the raw material from which he forms his ideas and thoughts. Communication with the interior man has not yet been opened up, except insofar as he is able to take in and hold on to those impressions. The innocence which exists in him at this time is solely external, not internal, because true innocence resides within wisdom. But the Lord uses this - his external innocence - to bring order into what enters through the senses. If innocence did not come to him from the Lord in that first period no foundation would ever be laid down on which the intellectual or rational degree of the mind proper to a human being could be established.

[3] From childhood to early youth communication is opened up with the interior natural, by the person's learning about what is decent, public-spirited, and honourable, both through what parents and teachers tell him and through his own efforts to find out about such matters. During early youth to later youth however communication is opened up between the natural and the rational, by his learning about what is true and what is good so far as his public life and private life are concerned, and above all about what is good and what is true so far as his spiritual life is concerned, all of which he learns about through listening to and reading the Word. Indeed insofar as he uses truths to immerse himself in good deeds, that is, insofar as he puts the truths he learns into practice, the rational is opened up; but insofar as he does not use truths to immerse himself in good deeds, or does not put truths into practice, the rational is not opened up. Nevertheless the things he has come to know remain within the natural; that is to say, they remain in his memory, left on the doorstep so to speak outside the house.

[4] But insofar - during these years and the next period of life - as he impairs the things he knows, refuses to accept them, and acts contrary to them, that is, insofar as he believes falsities and practises evils instead, the rational is closed, as is the interior natural also. But in spite of that, the Lord's Divine Providence enables communication to remain open enough to give him the ability to understand the good or truth he knows about. But he does not make these his own unless he truly repents and for a long while after that wrestles with falsities and evils. With people however who allow themselves to be regenerated the opposite takes place; for gradually, that is, in consecutive stages, their rational is opened up, the interior natural then becoming ranged in order beneath it, and the exterior natural beneath that. This occurs especially in the period from late youth to adulthood; it also continues in progressive stages to the final period of those regenerating people's lives, and after that in heaven for ever. From all this one may know what constitutes a person's interior natural and what his exterior natural.
