915. 21:20 The first foundation was jasper, the second sapphire, the third chalcedony, the fourth emerald, the fifth sardonyx, the sixth sardius, the seventh chrysolite, the eighth beryl, the ninth topaz, the tenth chrysoprase, the eleventh jacinth, and the twelfth amethyst. This symbolizes all of the doctrines of the New Church from the Word's literal sense in their order, with those who turn directly to the Lord and live in accordance with the Ten Commandments by refraining from evils as being sins; for they and no others possess a doctrine of love toward God and love for the neighbor, which are the two foundations of religion.

The twelve foundations of the wall symbolize all the doctrines of the New Jerusalem from the literal sense of the Word, as may be seen in nos. 902, 914 above. Precious stones in general symbolize all the truths in the doctrine of the New Jerusalem from the Word with the spiritual sense shining through, as may be seen in nos. 231, 540, 726, 911, 914 above. Each of the stones here symbolizes some particular truth with the spiritual meaning thus shining through. That the Word's literal sense in respect to its doctrines corresponds to precious stones of every kind may be seen in The Doctrine of the New Jerusalem Regarding the Sacred Scripture, nos. 43-45.

[2] Two colors in general that shine through in precious stones are the color red and the color white. The rest of the colors, such as green, yellow, blue, and many others, are composites of these, modified by shades of gray. The color red symbolizes the goodness of love, and the color white symbolizes the truth of wisdom. The color red symbolizes the goodness of love because it takes its origin from the fire of the sun, and the fire of the sun in the spiritual world is, in its essence, the Lord's Divine love, thus the goodness of love. And the color white symbolizes the truth of wisdom because it takes its origin from the light that emanates from the fire of that sun, and that emanating light is, in its essence, Divine wisdom, thus the truth of wisdom. Shades of gray take their origin from that fire and light shaded, which is ignorance.

[3] However, to explain in detail just what good and just what truth is symbolized by each stone would be too lengthy a task. Nevertheless, to learn what good and truth each stone symbolizes in this list, see the exposition of chapter 7 above, Revelation 7:5-8, nos. 349-361, where the subject was the twelve tribes of Israel. For each stone here has the same symbolism as each tribe named there, since the twelve tribes described there likewise symbolize all the goods and truths of the church and its doctrine in their order. Consequently we are also told in this chapter, verse 14, that on these twelve foundations were written the names of the twelve apostles of the Lamb, and the twelve apostles symbolize all of the doctrines regarding the Lord and living in accordance with His commandments (no. 903).

The twelve stones here also have the same symbolism as the twelve precious stones in the breastpiece of Aaron, called the Urim and Thummim, as described in Exodus 28:15-21, which we explained one by one in Arcana Coelestia (The Secrets of Heaven), 9856-9882 with the difference that the stones there had on them the names of the twelve tribes of Israel, while these have on them the names of the twelve apostles of the Lamb.

[4] That the foundations were laid with precious stones is something we are also told in Isaiah:

O you afflicted one..., behold, I will lay your stones with antimony. I will set your foundations in sapphires..., and your gates in carbuncle stones... All your children have been taught by Jehovah... (Isaiah 54:11-13)

The afflicted one means a church to be established by the Lord among gentiles.

In Isaiah as well:

...thus said the Lord Jehovih: ."..I will lay in Zion a foundation stone, a tried stone, a precious cornerstone, a sure foundation... I will make judgment the rule, and justice the plumb line...." (Isaiah 28:16-17)

[5] Since every doctrinal truth from the Word is founded on an acknowledgment of the Lord, therefore the Lord is called the Stone of Israel in Genesis 49:24, and the cornerstone which the builders rejected in Matthew 21:42, Mark 12:10-11. That the cornerstone is a foundation stone is clear from Jeremiah 51:26.

In many places in the Word the Lord is also called a rock. Thus He meant Himself by the rock when He said, "On this rock I will build My church" (Matthew 16:18-19). The rock symbolizes the Lord in respect to the Divine truth in the Word.

Everything connected with the church and its doctrine relates to these two points, that one must turn directly to the Lord, and that one must live in accordance with the Ten Commandments by refraining from evils as sins. Thus everything connected with the doctrine relates to love toward God and love for the neighbor, something that will be seen in The Doctrines of the New Jerusalem Regarding Charity, where these precepts will be expounded in turn.

902. 21:14 And the wall of the city had twelve foundations. This symbolically means that the Word in its literal sense contains all of the doctrines of the New Church.

The wall of the city symbolizes the Word in its literal sense (no. 898), and its twelve foundations symbolize all of the doctrines of the church - its foundations symbolizing doctrines, and the number twelve all. The church, moreover, is founded on doctrine, for it teaches how a person is to believe and live, and its doctrine is to be drawn only from the Word. That it is to be drawn from the Word's literal sense may be seen in The Doctrine of the New Jerusalem Regarding the Sacred Scripture, nos. 50-61.

Since the twelve foundations of the wall of the city New Jerusalem symbolize all of the church's doctrine, and the church is a church by virtue of its doctrine, therefore its foundations are described in more detail in verses 19 and 20 below.

The foundations of the earth are mentioned a number of times in the Word, and they do not mean the foundations of the earth, but the foundations of the church, inasmuch as the earth symbolizes the church (no. 285). And the foundations of the church are only ones that come from the Word and are called doctrines. For it is the Word itself that provides a foundation for the church.

[2] Doctrines drawn from the Word are symbolized by foundations also in the following passages:

Have you not understood the foundations of the earth? (Isaiah 40:21)

I will put My words in your mouth... to plant the heavens and found the earth... (Isaiah 51:16)

They do not acknowledge, they do not understand, they walk in darkness, all the foundations of the earth shake. (Psalms 82:5)

...the Word of Jehovah... who stretches out the heavens, lays the foundations of the earth, and forms the spirit of man within him. (Zechariah 12:1)

Jehovah... kindled a fire in Zion, which has devoured its foundations. (Lamentations 4:11)

The impious... shoot in darkness the upright in heart, because the foundations are being destroyed... (Psalms 11:2-3)

Hear, O mountains, Jehovah's quarrel, you strong foundations of the earth; for Jehovah has a quarrel with His people... (Micah 6:2)

...the floodgates on high are open, and the foundations of the earth are shaken. The earth is violently broken, the earth is split open, the earth is shaken... (Isaiah 24:18-20)

And so on elsewhere, as in Isaiah 14:32; 48:13; 51:13; Psalms 24:2; 102:25; 104:5-6; 2 Samuel 22:8, 16.

Whoever does not think that the earth symbolizes the church cannot help but think only naturally, even materially, when he reads in these places about the foundations of the earth. So it would be also if he were not to think of the city Jerusalem here as symbolizing the church when he reads about its wall, gates, foundations, streets, dimensions, and more, which are described in this chapter as features of a city, when in fact they are features of the church and so must be interpreted not materially, but spiritually.
