903. And on them the names of the twelve apostles of the Lamb. This symbolizes all of the doctrines from the Word regarding the Lord and living in accordance with His commandments.

The foundations had the names of the twelve apostles of the Lamb written on them because the twelve apostles symbolize the Lord's church and everything connected with it (nos. 79, 233, 790), in this case the church in respect to all of its doctrines, because their names were written on the twelve foundations, which symbolize all of the doctrines of the New Jerusalem (no. 902). The twelve names symbolize its whole character, and its whole character has to do with two elements in the doctrine and so in that church: the Lord and living in accordance with His commandments. Therefore these are what are symbolized.

All of the doctrines of the New Jerusalem relate to these two elements, because they are its universal tenets on which all of its particular ones depend, and they are the essential elements from which all of its outward expressions originate. Therefore they are, as it were, the soul and life in all of its doctrines.

They are, indeed, two elements, but one cannot be divorced from the other. For to divorce them would be like divorcing the Lord from mankind, or mankind from the Lord, and in that case there would be no church.

These two elements are joined together like the two tables of the Ten Commandments, one of which contains commandments having to do with the Lord, and the other commandments having to do with people. There they are called a covenant, and a covenant symbolizes conjunction.

Think what the case would be with the tables of the Ten Commandments if only the first were to remain and the second were to be snatched away. Or if the second were to remain and the first were to be snatched away. Would it not be as though God did not see mankind, or as though mankind did not see God? Or as though one abandoned the other?

We say this to make it known that everything connected with the doctrine of the New Jerusalem relates to love toward the Lord and love for the neighbor. To love the Lord is to have faith in the Lord and obey His commandments, and to obey His commandments is to love the neighbor, since to obey the Lord's commandments is to be of useful service to the neighbor. People who love the Lord are those who obey His commandments, as the Lord Himself teaches in John 14:21-24. And love toward the Lord and love for the neighbor are the two commandments on which hang the Law and the Prophets (Matthew 22:37-40). The Law and the Prophets mean the Word in its entirety.

486. And the angel stood by, saying, "Rise and measure the temple of God, the altar, and those who worship there." This symbolizes the Lord's presence and His command to see and learn the state of the church in the New Heaven.

The Lord is meant by the angel, here as in nos. 5, 415, and elsewhere, since an angel does nothing of himself but is impelled by the Lord. That is why the angel said, "I will give power to my two witnesses" (verse 3), when they were the Lord's witnesses. The angel's standing by symbolizes the Lord's presence, and his speaking symbolizes the Lord's command. To rise and measure means, symbolically, to see and learn. We will see below that to measure means, symbolically, to learn and investigate the character of a state.

The temple, altar, and those who worship there symbolize the state of the church in the New Heaven - the temple symbolizing the church in respect to its doctrinal truth (no. 191), the altar symbolizing the church in respect to the goodness of its love (no. 392), and those who worship there symbolizing the church in respect to its formal worship as a result of those two elements. Those who worship symbolize here the reverence that is a part of formal worship, since the spiritual sense is a sense abstracted from persons (nos. 78, 79, 96), as is apparent here also from the fact that John is told to measure the worshipers. These three elements are what form the church: doctrinal truth, goodness of love, and formal worship as a result of these.

[2] That the church meant is the church in the New Heaven is apparent from the last verse of this chapter, where we are told that "the temple of God was opened in heaven, and the ark of His covenant was seen in His temple" (verse 19).

This chapter begins with the measuring of the temple in order that the state of the church in heaven might be seen and learned before its conjunction with the church in the world. The church in the world is meant by the court outside the temple, which John was not to measure, because it had been given to the gentiles (verse 2). The same church is then described by the great city called Sodom and Egypt (verses 7, 8). But after that great city fell (verse 13), it follows that the church became the Lord's (verses 15ff.).

It should be known that the church exists in the heavens just as on earth, and that the two are united like the inner and outer selves in people. Consequently the Lord provides the church in heaven first, and from it, or by means of it, then the church on earth. That is why the New Jerusalem is said to come down from God out of the New Heaven (Revelation 21:1-2).

The New Heaven means a new heaven formed from Christians, as described several times in the following chapters.

[3] To measure means, symbolically, to learn and investigate the character of a thing because the measure of something symbolizes its character or state. All the measurements of the New Jerusalem (chapter 21) have this symbolic meaning, as does the statement there that the angel who had the gold reed measured the city and its gates, and that he measured the wall to be one hundred and forty-four cubits, the measure of a man which is that of an angel (verses 15, 17). Moreover, because the New Jerusalem symbolizes the New Church, is it apparent that to measure it and its component parts means, symbolically, to learn its character.

Measuring has the same symbolic meaning in Ezekiel, where we read that an angel measured the house of God: the temple, the altar, the court, and the chambers (Ezekiel 40:3-17; 41:1-5, 13-14, 22; 42:1-20, and 43:1-27). Also that he measured the waters (47:3-5, 9). Therefore the prophet is told:

...show the temple to the house of Israel, that they may be ashamed of their iniquities; and they shall measure the pattern... and... its exits and its entrances, and all its patterns..., so that they may keep its whole design... (Ezekiel 43:10-11)

Measuring has the same symbolic meaning in the following places:

I raised my eyes..., and behold, a man with a measuring line in his hand. So I said, "Where are you going?" And he said to me, "To measure Jerusalem...." (Zechariah 2:1-2)

He stood and measured the earth. (Habakkuk 3:6)

(The Lord Jehovih) has measured the waters in the hollow of His hand, and gauged heaven with a span... and weighed the mountains in scales and the hills in a balance. (Isaiah 40:12)

Where were you when I laid the foundations of the earth? ...Who determined its measurements? ...Or who stretched the line upon it? (Job 38:4-5)
