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.

898. 21:12 It had a great and high wall. This symbolizes the Word in its literal sense from which the doctrine of the New Church comes.

Since the holy city Jerusalem means the Lord's New Church in respect to its doctrine, its wall can only mean the Word in its literal sense, from which its doctrine comes; for the literal sense protects the spiritual meaning that lies within, as a wall protects a city and its inhabitants.

That the literal sense is the foundation, containing vessel, and buttress of the Word's spiritual meaning may be seen in The Doctrine of the New Jerusalem Regarding the Sacred Scripture, nos. 27-36; and that the literal sense serves as a safeguard to keep the Divine truths within from being injured - truths which constitute the Word's spiritual meaning - may be seen in no. 97 of the same work. Also, that the church's doctrine is to be drawn from the Word's literal sense and verified by it, in nos. 50-61 there.

The wall is said to be great and high because it means the Word in respect to its Divine goodness and Divine truth, for greatness is predicated of goodness, and height of truth, as in no. 896 above.

[2] A wall symbolizes something that protects, and when mentioned in reference to the church, it symbolizes the Word in its literal sense, as it does also in the following places:

I have set watchmen on your walls, O Jerusalem; they shall not keep silent day or night, who make mention of Jehovah... (Isaiah 62:6)

They shall call you the City of Jehovah, the Zion of the Holy One of Israel... And you shall call your walls salvation, and your gates praise. (Isaiah 60:14, 18)

(Jehovah) will be a wall of fire all around her, and... the glory in her midst. (Zechariah 2:5)

Men of Arvad... were on your walls..., and the men of Gammad... hung their shields on your walls all around, and made your beauty perfect. (Ezekiel 27:11)

The last is said of Tyre, which symbolizes the church in respect to its concepts of truth from the Word.

Run about through the streets of Jerusalem, and see... if there is anyone who... seeks the truth... Go up on her walls and cast them down. (Jeremiah 5:1, 10)

Jehovah has purposed to destroy the wall of the daughter of Zion... ...He has caused the rampart and wall... to lament, to languish together... The Law and her prophets are no more... (Lamentations 2:8-9)

They will run about in the city, they will run on the wall; they will climb up into the houses, they will enter through the windows... (Joel 2:9)

These passages refer to falsifications of truth.

Day and night (the impious) go around (in the city) on its walls... Destructions are in their midst. (Psalms 55:10-11)

And so on elsewhere, as in Isaiah 22:5; 56:5; Jeremiah 1:15; Ezekiel 27:11; Lamentations 2:7.

That a wall symbolizes the Word in its literal sense is clearly apparent from the following verses in the present chapter, which describe at some length the wall of the city and its gates, foundations and dimensions. That is because the doctrine of the New Church, which the city symbolizes, comes only from the Word's literal sense.
