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.

4280. In that lower sense the words 'he touched the hollow of Jacob's thigh' mean where conjugial love is joined to natural good. This is clear from the meaning of 'the hollow of the thigh' as the place where conjugial love is linked to it, see above in 4277. The reason why the place where it is linked to natural good is meant is that it is the place where the thigh is joined to the feet. 'The feet' in the internal sense means natural good, see 2162, 3147, 3761, 3986.

[2] As regards 'the thigh' meaning conjugial love and 'the feet' natural good, that is one of those realities known in the past which have grown old and died. The Ancient Church, which existed in an age of representatives and meaningful signs, was extremely well acquainted with these meanings, such knowledge of them constituting their intelligence and wisdom. Indeed it constituted the intelligence and wisdom not only of those who belonged to the Church but also of those outside the Church, as becomes clear from the oldest books written by gentiles and from the stories in them which are nowadays called myths - for meaningful signs and representatives spread from the Ancient Church to those gentiles. With these also 'the thighs and loins' meant that which belonged to marriage, and 'the feet' things that were natural. The origin of this meaning of 'the thighs and the feet' lies in the correspondences of all the members, organs, and viscera of the human being with the Grand Man, which - that is to say, such correspondences - are being dealt with now at the ends of chapters. The correspondences with the thigh and the feet will be discussed again further on, where actual experience will be used to corroborate that their meaning is as indicated above.

[3] These things are bound to seem like enigmas at the present day because, as has been stated, that knowledge has grown very old indeed and died. Yet how far that knowledge excels other types of knowledge becomes clear from the consideration that the internal sense of the Word cannot possibly be known without that knowledge, as well as for the reason that the angels present with man perceive the Word according to that sense. It becomes clear also from the consideration that by means of that knowledge man is provided with communication with heaven. And what is unbelievable, the internal man himself does not think in any other way; for when the external man understands the Word according to the letter the internal man does so according to the internal sense, though while living in the body a person is not at all conscious of doing so. This becomes particularly clear from the fact that when anyone enters the next life and becomes an angel he has no need to learn the internal sense but knows it instinctively, so to speak.

[4] What conjugial love is which is meant by 'the thighs' and also by 'the loins', see 995, 1123, 2727-2759; and conjugial love is the basic love of all loves, 686, 3021. Consequently people who have genuine conjugial love in them also have celestial love, which is love to the Lord, and spiritual love, which is charity towards the neighbour. For this reason the expression 'conjugial love' is used to mean not only that love itself but also all celestial and spiritual love. These kinds of love are said to be joined to natural good when the internal man is joined to the external, that is, the spiritual man to the natural - that joining together of them being meant by 'the hollow of the thigh'. The fact that with Jacob and his descendants in general no such conjunction existed will be evident from what follows, for this is the subject dealt with here in the internal historical sense.
