924. 21:27 But there shall not enter it anything unclean, or that creates an abomination or a lie. This symbolically means that no one is received into the Lord's New Church, which is the New Jerusalem, who adulterates the goods in the Word and falsifies its truths, and who does evils deliberately and so also devises falsities.

Not to enter in means, symbolically, not to be received, as before. Something unclean symbolizes spiritual licentiousness, which is an adulteration of the Word's goodness and a falsification of its truth (nos. 702, 728). For this is absolutely unclean and impure, inasmuch as the Word is absolutely clean and pure, and it is defiled with evils and falsities when it is corrupted. That adultery and licentiousness correspond to an adulteration of the Word's goodness and a falsification of its truth may be seen in nos. 134, 632. To create an abomination or a lie means, symbolically, to do evils and so also to devise falsities. Abominations symbolize evils of every kind, especially those named in the Ten Commandments (no. 891), and a lie symbolizes falsities of every kind, here the falsities that accompany evil, which in themselves are evils. Thus they are falsities used to justify evil, which are the same as evils affirmed.

A lie symbolizes doctrinal falsity because that is what a spiritual lie is. To create a lie, therefore, symbolically means to live in accordance with doctrinal falsities.

[2] That a lie in the Word symbolizes doctrinal falsity may be seen from the following passages:

We have made a covenant with death, and with hell we have produced a vision... ...we have made a lie our refuge, and in falsehood we have hidden ourselves. (Isaiah 28:15)

Everyone deceives his neighbor, and they do not speak the truth; they have taught their tongue to speak a lie. (Jeremiah 9:5)

...this is a rebellious people, lying children..., who will not hear the law of Jehovah. (Isaiah 30:9)

Behold, I am against those who prophesy lying dreams..., and tell them in order to lead My people astray by their lies... (Jeremiah 23:32)

The diviners see a lie, and speak false dreams. (Zechariah 10:2)

(The diviners) see vanity and a lying divination... Therefore..., because you speak vanity and see a lie, behold, for that reason I am against you..., (so that) My hand is against the prophets who speak... a lie. (Ezekiel 13:6-9, cf. 21:29)

Woe to the bloody city! It is all full of lying and robbery. (Nahum 3:1)

In the prophets of Jerusalem I have seen a shocking obstinacy, committing adultery and walking in lies. (Jeremiah 23:14)

From the prophet even to the priest, everyone devises lies. (Jeremiah 8:10)

(In Israel) they have devised lies. (Hosea 7:1)

You are of your father the devil... He was a murderer from the beginning..., because there is no truth in him. When he speaks a lie, he speaks on his own, for he is the speaker of a lie and the father of it. (John 8:44)

Here, too, a lie means falsity.

400. And they were cast down to the earth, and a third of the trees were burned up. This symbolically means that in people concerned with the internal elements of the church and caught up in faith alone, all affection for truth and perception of truth, which make a person a person of the church, had perished.

To be shown that the earth to which the hail and fire mingled with blood were cast down symbolizes the church among people concerned with its internal elements and caught up in faith alone, and that these are the clergy, see no. 398 above. A third part symbolizes everything in relation to truth, as a fourth part symbolizes everything in relation to goodness (no. 322). That the number three symbolizes all, completeness, and totally, will be seen in no. 505 below. A third part or a third consequently has the same symbolism.

To be burned up means, symbolically, to perish - in this case to perish by falsity springing from a hellish love, which is what is meant by hail and fire mingled with blood, as just explained in no. 399 above.

A tree symbolizes a person. And because a person is human by virtue of the affection of his will and the perception of his intellect, these also are therefore symbolized by a tree.

There is as well a correspondence between a person and a tree. Consequently in heaven one sees paradisal parks formed of trees that correspond to the affections and resulting perceptions of angels. And elsewhere, in hell, there are forests formed of trees that bear harmful fruit, in accordance with their correspondence to the lusts and resulting thoughts of the inhabitants there.

That trees in general symbolize people in respect to their affections and consequently perceptions can be seen from the following passages:

All the trees of the field shall know that I, Jehovah, bring low the tall tree and raise up the low tree, and dry up the green tree and make the dry tree burgeon. (Ezekiel 17:24)

Blessed is the man who trusts in Jehovah... He shall be like a tree planted by the waters... Nor will He cease from bearing fruit. (Jeremiah 17:7-8)

Blessed is the man...(whose) delight is in the law... He shall be like a tree planted by rivers of water, that brings forth its fruit in its season... (Psalms 1:1-3)

Praise Jehovah... you fruitful trees... (Psalms 148:7-9)

Satiated are the trees of Jehovah... (Psalms 104:16)

...the ax is laid to the root of the tree... ...every tree which does not bear good fruit will be cut down... (Matthew 3:10; cf. 7:16-20)

Either make the tree good and its fruit good, or else make the tree rotten and its fruit rotten; for a tree is known by its fruit. (Matthew 12:33, cf. Luke 6:43-44)

...I will kindle a fire..., (which) shall devour every green tree and every dry tree... (Ezekiel 20:47)

Since a tree symbolizes a person, therefore it was a statute that the fruit of a tree serving for food in the land of Canaan be uncircumcised (Leviticus 19:23-25). Furthermore, that when the people besieged a city, they not take an axe to any tree bearing good fruit (Deuteronomy 20:19-20). And still other regulations, which we do not cite here owing to their number.
