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.

2701. 'God opened her eyes' means intelligence. This is clear from the meaning of 'opening' - and that it is God who did so - and also from [the meaning] of 'the eyes', as conferring intelligence; for 'the eyes' means the understanding, see 212, as also does 'sight' or 'seeing', 2150, 2325. The expression 'God opens the eyes' is used when He opens interior sight or the understanding, which opening is accomplished by means of an influx into the rational part of the person's mind, or rather into the spiritual part of his rational. The route taken by this influx is the soul, that is, the internal route, of which the person himself is not aware. This influx is his state of enlightenment in which the truths he hears or reads about are confirmed for him by a kind of perception existing within, in the understanding part of his mind. The person himself believes that this enlightenment is innate within himself and that it springs from his own power of understanding; but in this he is very much mistaken. This enlightenment consists in an influx from the Lord by way of heaven into that person's dim, mistaken, and specious sight of things, and by means of the good there causes the things which he believes to become imitations of truth. Only those who are spiritual however are blessed with enlightenment in spiritual matters of faith; and this is the meaning of the expression 'God opens the eyes'.

[2] The reason why 'the eye' means the understanding is that the sight belonging to the body corresponds to that belonging to its spirit, which is the understanding. And because it has this correspondence 'the eye' in the Word, in almost every place where it is mentioned, means the understanding, even where people believe something other is meant, as where the Lord says in Matthew,

The lamp of the body is the eye. If the eye is sound, the whole body is full of light. If the eye has been evil the whole body has been made full of darkness. If therefore the light is darkness, how great is the darkness! Matthew 6:22-23; Luke 11:34.

Here 'the eye' is the understanding, the spiritual constituent of which is faith, as also is shown by the explanation added here - 'if therefore the light is darkness, how great is the darkness!' Similarly in the same gospel,

If your right eye causes you to stumble, pluck it out and throw it away from you. Matthew 5:29; 18:9.

'The left eye' is the understanding part of the mind, whereas 'the right eye' is its affection. The command to pluck out the right eye means that if it causes one to stumble one's affection must be disciplined.

[3] In the same gospel,

Blessed are your eyes, for they see, and your ears, for they hear. Matthew 13:16.

And in Luke, Jesus said to the disciples, Blessed are the eyes which see what you see. Luke 10:23.

Here 'the eyes which see' means intelligence and faith, for it was not the mere fact that they saw the Lord and also His miracles and works that caused any one of the disciples to be blessed but the fact that they could grasp things with their understandings and had faith, meant by 'seeing with the eyes', and that they were obedient, meant by 'hearing with the ears'. As regards 'seeing with the eyes' meaning to see with the understanding and also to have faith, see 897, 2325. For the understanding is the spiritual complement of sight, and faith the spiritual complement of the understanding. The sight of the eye is received from the light of the world, the sight of the understanding from the light of heaven flowing into things which belong to the light of the world; but the sight of faith is received from the light of heaven. This is the origin of such phrases as seeing with the understanding and seeing with faith. 'Hearing with the ear' means being obedient, see 2542.

[4] In Mark,

Jesus said to the disciples, Do you not yet know nor understand? Do you still have your heart hardened? Having eyes do you not see, and having ears do you not hear? Mark 8:17-18.

Here it is evident that 'having eyes but not seeing' means not wishing to understand and not believing. In Luke,

Jesus said of the city, Would that you knew the things that make for your peace! But such is hidden from your eyes. Luke 19:41-42.

And in Mark,

By the Lord has this been done, and it is marvellous in our eyes. Mark 12:11.

Here 'hidden from the eyes' and 'marvellous in the eyes' mean to be so to the understanding, as is well known to everyone from the meaning of 'the eyes' even in everyday speech.
