According to Swedenborg, a person's name in the Bible represents his or her entire spiritual nature, their whole state of love (good or evil) and thought (from heavenly wisdom to infernal insanity). This is why the name of the Lord is so important; it represents and embodies His perfect love and perfect wisdom, which is everything that we should worship and follow. It's easy to see that names are important in the Bible. Jehovah changed Abram and Sarai to Abraham and Sarah, changed Jacob to Israel and included in the Ten Commandments the order that believers "shall not take the name of the Lord your God in vain." In the New Testament, Zacharias was told to name John the Baptist "John," and both Joseph (Matthew 1:21) and Mary (Luke 1:31) were told to name Jesus "Jesus." Jesus himself renamed Simon as Peter, and included the phrase "hallowed be thy name" in the Lord's prayer.

(Odkazy: Luke 1)

861. 20:9 And they went up over the breadth of the earth and surrounded the camp of the saints and the beloved city. This symbolically means that, being roused up by followers of the dragon, these people scorned every truth in the church and attempted to destroy everything connected with the New Church and its fundamental doctrine regarding the Lord and life.

To go up over the breadth of the earth means, symbolically, to scorn every truth in the church, because going up over symbolically means to transcend and bypass, thus to scorn. And the breadth of the earth symbolizes the truth in the church, as will be seen below. To surround the camp of the saints means, symbolically, to besiege and try to destroy everything connected with the New Church, as will be seen in the number following next. And the beloved city symbolizes the doctrine of the New Church. That a city symbolizes a church's doctrine may be seen in nos. 194, 501, 502, 712 above. The city is called beloved because its doctrine teaches about the Lord and how to live, as it is the doctrine of the New Jerusalem that is meant here.

That this is the symbolic meaning of these words, no one can see except as a consequence of the Word's spiritual sense. For it cannot possibly enter a person's thought that the breadth of the earth symbolizes the truth in a church, that the camp of the saints symbolizes everything connected with the New Church, both its truths and its goods, and that the city symbolizes its doctrine. Lest the mind remain in a state of doubt, therefore, we must demonstrate what breadth and the camp of the saints symbolize in the spiritual sense, which will make it possible for one to see afterward that the meaning of these words is as we have said.

[2] The breadth of the earth symbolizes the truth in a church because the spiritual world has in it four zones - eastern, western, southern and northern - and the eastern and western zones form its longitude or length, while the southern and northern zones form its latitude or breadth. Moreover, because the inhabitants in the eastern and western zones are ones impelled by the goodness of love, and therefore the east and west symbolize goodness, so likewise does longitude or length. And because the inhabitants in the southern and northern zones are ones impelled by truths of wisdom, and therefore the south and north symbolize truth, so likewise does latitude or breadth. But for more on this subject, see the book Heaven and Hell (London, 1758), nos. 141-153.

That breadth symbolizes truth can be seen from the following passages in the Word:

You (Jehovah) have not shut me up into the hand of the enemy; You have set my feet in the broad place. (Psalms 31:8)

Out of distress I called on Yah; He answered me in the broad place. (Psalms 118:5)

(Jehovah) led me out into the broad place; He delivered me... (Psalms 18:19)

...I am raising up the Chaldeans, a bitter and impetuous nation which marches into the breadths of the earth... (Habakkuk 1:6)

(The Assyrian) will pass through Judah, He will overflow and pass over..., and the spreading of his wings will fill the breadth... (Isaiah 8:8)

...Jehovah will pasture them like a lamb in broad pasture. (Hosea 4:16)

And so on elsewhere, as in Psalms 4:1; 66:12, Deuteronomy 33:20.

[3] Nothing else is meant by the breadth of the city New Jerusalem (Revelation 21:16). For since the New Jerusalem means the New Church, its breadth and length cannot symbolically mean its breadth and length, but its truth and goodness. These, indeed, are the measures of a church.

So also in Zechariah:

I said (to the angel), "Where are you going?" He said..., "To measure Jerusalem, to see how great its width is and how great its length." (Zechariah 2:2)

So likewise the breadth and length of the new temple and new earth in Ezekiel, chapters 40-47.

So, too, the length and breadth of the altar of burnt offering, of the Tabernacle, of the table of showbread, of the altar of incense, and of the ark within. So also the length and breadth of the temple in Jerusalem, and of many other things whose dimensions are given.
