425. Up to now the world has not known that 'bronze' means natural good, nor indeed that every metal mentioned in the Word has some definite meaning in the internal sense. For example 'gold' means celestial good, 'silver' spiritual truth, 'bronze' natural good, 'iron' natural truth, and so on with all the rest. The same applies to stone and wood. These were the meanings of the gold, silver, bronze, and wood in the Ark and the Tabernacle, and of similar objects in the Temple, which in the Lord's Divine mercy will be dealt with later on. In the Prophets it is plain that such things are meant, as in Isaiah,

You will suck the milk of nations, and the breast of kings will you suck. Instead of bronze I will bring gold, and instead of iron, I will bring silver, and instead of wood, bronze, and instead or stones, iron. And I will make peace your assessment and righteousness your tax-collectors. Isaiah 60:16-17.

This refers to the Coming of the Lord and to His kingdom, and to the celestial Church. 'Gold instead of bronze' means celestial good instead of natural good. 'Silver instead of iron' means spiritual truth instead of natural truth. 'Bronze instead of wood' means natural good instead of bodily good. 'Iron instead of stones' means natural truth instead of sensory truth. In Ezekiel,

Javan, Tubal, and Meshech, they were your merchants in the souls of men, and they gave vessels of bronze for your merchandise. Ezekiel 27:13

This refers to Tyre, which means people who are in possession of spiritual and celestial riches. 'Vessels of bronze' stands for natural goods. In Moses,

A land whose stones are Iron, and from whose mountains you will dig out bronze. Deuteronomy 8:9.

Here similarly 'stones' stands for sensory truth, 'iron' for natural or rational truth, and 'bronze' for natural good. In the cases of the four living creatures or the cherubim seen by Ezekiel, whose feet sparkled like burnished bronze, Ezekiel 1:7, 'bronze' in a similar way means natural good, for the human foot represents that which is natural. Something similar was seen by Daniel,

A man clothed in linen whose loins were girded with gold of Uphaz and whose body was like tarshish. ¹ His arms and feet were like the appearance of burnished bronze. Daniel 10:5-6

And for the fact that the bronze serpent mentioned in Numbers 21:9 represented the Lord's good, sensory and natural, see what has been said already [in 197].

Footnotes:

9777. '[And] all its pins and all the pins of the court, [they shall be made] from bronze' means everything that joins together and strengthens the two heavens, the middle and the lowest, through good. This is clear from the meaning of 'pins' as things that serve to join and strengthen, dealt with below; from the meaning of the dwelling-place, to which 'its' relates here, as heaven, in particular the middle heaven, dealt with in 9594, 9596, 9632; from the meaning of 'the court' as the lowest heaven, dealt with in 9741; and from the meaning of 'bronze' as external good, dealt with in 425, 1551.

[2] The reason why things that serve to join and strengthen are meant by 'pins' or pegs is that these articles do so. They have a similar meaning wherever else they are mentioned in the Word, as in Isaiah,

Enlarge the place of your tent, and let them stretch out the curtains of your dwelling-places; do not stop [them]. Lengthen your ropes, and make your pegs firm. Isaiah 54:2.

This refers to the New Church founded by the Lord. 'Enlarging the place of the tent, and stretching out the curtains of the dwelling-places' stands for the enhancement of teachings that present what is good and true, and worship that springs from them, 9596. 'Long ropes' and 'the pegs' stand for a far-reaching connection among truths and full corroboration of them. As for the court, that this too had ropes, see Exodus 35:18; Numbers 3:37; 4:32.

[3] In Isaiah,

Look upon Zion. May your eyes see Jerusalem, a quiet dwelling-place, a tabernacle which is not overthrown. Its pegs will never be removed, and none of its ropes will be pulled away. Isaiah 33:20.

'Pegs' and 'ropes' here stand in like manner for what serves to corroborate or strengthen and join together. 'Peg' again stands for strengthening and joining together in Isaiah 41:7 and Jeremiah 10:4; but these verses refer to idols, by which teachings of what is false are meant, because they are the product of self-intelligence, 8941, 9424. A peg however on which something is hung means affixing and joining [one thing to another], in Isaiah 22:23-24, and in Ezekiel 15:3.
