904. 21:15 And he who talked with me had a gold reed to measure the city, its gates, and its wall. This symbolically means that to people who possess the goodness of love, the Lord grants a faculty for understanding and knowing the nature of the Lord's New Church as regards its doctrine and its introductory truths, and as regards the Word from which they are drawn.

He who spoke with me symbolizes the Lord speaking from heaven, because it was an angel speaking, one of the seven angels who had the seven bowls mentioned in verse 9, who means the Lord speaking from heaven (no. 895). A reed symbolizes a power or ability springing from the goodness of love - a reed symbolizing power or ability (no. 485), and gold the goodness of love (nos. 211, 726). To measure means, symbolically, to learn the character of a thing, thus to understand and know it (no. 486). The city, the holy Jerusalem, symbolizes the church in respect to its doctrine (nos. 879, 880). Its gates symbolize concepts of truth and goodness from the Word's literal sense, which are truths and goods owing to the spiritual life in them (no. 899). And the wall symbolizes the Word in its literal sense from which the doctrine and concepts come (no. 898).

It is apparent from this that "he who talked with me had a gold reed to measure the city, its gates, and its wall," symbolically means that to people who possess the goodness of love, the Lord grants a faculty for understanding and knowing the nature of the Lord's New Church as regards its doctrine and its introductory truths, and as regards the Word from which they are drawn.

[2] These symbolic meanings cannot be seen at all in the literal sense, for one sees in it only that an angel speaking with John had a gold reed with which to measure the city and its gates and wall. But even so, that these words contain another meaning, a spiritual meaning, is clearly apparent from the fact that the city Jerusalem does not mean a real city, but the church. Consequently everything said about Jerusalem as a city symbolizes such things as have to do with the church, and everything having to do with the church is, in itself, spiritual.

Such a spiritual meaning is present also in what is said in chapter 11 above, where we are told the following:

I was given a reed like a measuring rod. And the angel stood by, saying, "Rise and measure the temple of God, the altar, and those who worship there." (Revelation 11:1)

A similar spiritual meaning is present, too, in everything that the angel measured with a reed in Ezekiel 40; 41; 42; 43; 44; 45; 46; 47; 48. Also in these verses in Zechariah:

I raised my eyes and looked, 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, to see what its width is and what its length." (Zechariah 2:1-2)

Indeed, such a spiritual meaning is present in everything connected with the Tabernacle and in everything connected with the Temple in Jerusalem, whose measurements we are told, and also in the measurements themselves. And yet nothing of this can be seen in the literal sense.

900. And over the gates twelve angels, with names written on them, which are those of the twelve tribes of the children of Israel. This symbolizes the Divine truths and goods of heaven in those concepts, which are also the Divine truths and goods of the church, and at the same time safeguards to keep someone from entering into them unless he does so from the Lord.

The twelve angels symbolize here all the truths and goods of heaven, since in the highest sense angels symbolize the Lord, in a more general sense heaven, which is composed of angels, and in a more particular sense the truths and goods of heaven from the Lord. See nos. 5, 170, 258, 344, 415, 465, 647, 648, 657, 718. Here they symbolize the truths and goods of heaven, because the statement follows, "with names written on them, which are those of the twelve tribes of the children of Israel," and these symbolize all the truths and goods of the church (no. 349).

Being over the gates means, symbolically, in those concepts, inasmuch as "over" in the Word symbolically means "within." The reason is that the highest component in sequential order becomes the inmost in concurrent order. Consequently the third heaven is called both the highest heaven and the inmost heaven. That is why "over the gates" symbolically means in the concepts of truth. The names written on the angels symbolize their whole character, thus also the character within them, for every quality in outward expressions originates from inner attributes.

It is apparent that the same words symbolize safeguards to keep someone from entering the church without having those concepts from the Lord, because the angels were seen standing over the gates, and the names of the tribes of Israel were also written on them.

We say that the truths and goods of heaven and the church are present in the concepts coming from the Word that serve to introduce into the church, because when concepts of truth and good from the Word have in them a spiritual quality from heaven from the Lord, they are called not concepts, but truths. But if those concepts do not have in them a spiritual quality from heaven from the Lord, they are nothing more than articles of knowledge.
