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.

322. And power was given to them over a fourth of the earth, to kill. This symbolizes the destruction of all good in the church.

Since death means the extinction of a person's spiritual life, and hell his damnation, it follows that to kill here means to destroy the life of a person's soul. The life of the soul is spiritual life.

A fourth of the earth means, symbolically, all good in the church. The earth is the church (no. 285).

That a fourth means all good can be known only by someone who knows what numbers in the Word symbolize. The numbers two and four are said in application to goods, and they symbolize those goods. And the numbers three and six are said in application to truths, and they symbolize those truths. Thus a fourth part, or simply a fourth, symbolizes all good, while a third part, or simply a third, symbolizes all truth. Therefore to kill a fourth of the earth here means, symbolically, to destroy all good in the church.

Clearly he who sat on the pale horse was not given the power to kill a fourth part of the habitable earth.

[2] In addition, the number four in the Word symbolizes the union of goodness and truth.

That the number four has these symbolic meanings can, indeed, be confirmed from the Word, as by the four living creatures or cherubim in Ezekiel 1,3, 10; by the four chariots between two mountains in Zechariah 6:1; by the four horns in Zechariah 1:18ff.; by the four horns of the altar in Exodus 27:1-8, and Revelation 9:13; and by the four angels standing at the four corners of the earth, holding the four winds of the earth, in Revelation 7:1 (cf. Matthew 24:31). It can be confirmed, too, by the "visiting the iniquity to the third and fourth generation" in Numbers 14:18, and by the third and fourth generation mentioned elsewhere. By these passages in the Word and more, I say, one can confirm that the number four is said in application to goods, and that they symbolize those goods, and also the conjunction of goodness and truth. But because it would take a lengthy explanation of these passages to make this apparent, it is enough to briefly state that this is the meaning that the number four and a fourth part have in heaven.
