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.

2625. 'At the appointed time' means when the Rational was such that it was receptive. This becomes clear from the meaning of 'time'. There are two things which appear to be indispensable while a person lives in the world because they exist as essential elements of the natural order - those two things being space and time. Living in the world or natural order therefore is living in space and time. But these two cease to have any existence in the next life. They do, it is true, appear to exist to some extent in the world of spirits, the reason for this being that spirits recently arrived from life in the body bring with them mental pictures of natural things. But subsequently they perceive that space and time do not exist in that life but states instead, and that states in the next life correspond to extensions of space and of time within the natural order - states in respect to Being corresponding to those of space, and in respect to Manifestation to those of time. Regarding space or place, see 1274, 1379, 1380, 1382.

[2] From this anyone may see what kind of mental pictures a person is able to have while in the world or natural order regarding things which belong to the next life and about many arcana of faith. He may see that such a person is unwilling to believe those things unless he can take them in by means of objects that exist in the world, indeed by sensory evidence. For he cannot do other than suppose that if he were to divest himself of his mental pictures that have been formed from space and time, more so to divest himself of space and time themselves, he would cease to be anything at all and so would have nothing left to him from which he could perceive with his senses or have thoughts of anything apart from that which was unintelligible to him. But in actual fact quite the reverse is the case: the life of angels is such that it is the wisest and happiest of all.

[3] This is the reason why people's ages mentioned in the Word do not in the internal sense mean ages but states, so that in this verse 'old age' does not mean old age. Nor does any number mean a number but some specific state, as in the case of 'a hundred years' mentioned further on. From this it now becomes clear that 'the appointed time' means the state when the rational was such that it was receptive.

[4] As regards the specific teaching presented here - that the Divine Rational received being and was given manifestation from the Lord's Divine spiritual united to His Divine celestial, when the days had been completed for him to cast off the human and when the Rational was such that it was receptive (meant in the internal sense by 'Sarah conceived and bore to Abraham a son in his old age, at the appointed time') - the following needs to be known:

The human has its beginnings in the inmost part of the rational, see 2106, 2194. The Lord advanced gradually towards the union of the Human Essence with the Divine Essence, and of the Divine Essence with the Human Essence, 1864, 2033, 2523.

He did so by His own power, 1921, 2025, 2026, 2083, through continuing temptations and repeated victories, 1690, 1737, 1813, and through receiving revelations repeatedly from His own Divine, 1616, 2500, till at length He cast out the whole human from the mother, 1414, 1444, 2574.

And in this way He made His Human - as to the Rational - Divine, as taught by the things that occur in this verse.

From all this it is evident how the explanation 'when the days had been completed for Him to cast off the human and when the Rational was such that it was receptive' is to be understood.

[5] Some idea of this matter may be had from what happens to people who are being regenerated. The celestial things of love, and the spiritual things of faith, are instilled into them by the Lord not all at once but gradually; and when by means of those things a person's rational has become such that it is able to be receptive, he is for the first time becoming regenerate, mostly by means of temptations in which he overcomes. While these experiences are taking place the days are being completed to cast off the old man and put on the new. Regarding man's regeneration, see 677, 679, 711, 848, 986, 1555, 2475.
