835. These two were cast alive into the lake of fire burning with brimstone. This symbolically means that all of them were cast as they were into the hell where their loves of falsity and accompanying lusts for evil are found.

Being alive means, symbolically, as they were. These two, namely the beast and the false prophet, symbolize all those people who have professed faith alone and are inwardly evil, both the laity and the clergy, as said just above in no. 834. The lake of fire burning with brimstone symbolizes the hell where those people are found who are impelled by loves of that falsity and at the same time lusts for evil. A lake symbolizes an abundance of falsities, as will be seen below. Fire symbolizes love, here these people's love of falsity. Fire symbolizes love in both senses, good and evil, as may be seen in nos. 468, 494, 599, and here it symbolizes a love of falsity, because it is described as a lake of fire. Brimstone symbolizes a lust for evil and its accompanying falsities (no. 452).

Something similar is said about the dragon and these two in the next chapter, in these words:

The devil (that is, the dragon) that deceived them, was cast into the lake of fire and brimstone where the beast and the false prophet are. And they will be tormented day and night forever and ever. (Revelation 20:10)

[2] It should be known that the hell where people like this are appears at a distance as a lake of fire with a green flame like that of brimstone or sulfur. But those who are there do not see this. They are shut up in their workhouses where they vehemently argue with each other. Sometimes knives appear in their hands, which they brandish in a threatening manner to keep from yielding. It is their love of falsity together with their lusts for evil that occasions the appearance of such a lake. This appearance is produced because of its correspondence.

[3] That a lake symbolizes a place with an abundance of truth, and in an opposite sense, therefore, a place with an abundance of falsity, can be seen from the Word. A place with an abundance of truth from the following:

...waters shall burst forth in the wilderness, and streams in the desert. The parched ground shall become a lake... (Isaiah 35:6-7)

I will make the wilderness into a lake of water, and the dry land into springs of water. (Isaiah 41:18, cf. Psalms 107:33, 35)

I will make the rivers into islands, and I will dry up the lakes. (Isaiah 42:15)

...the God of Jacob, who turned the rock into a lake of water, and the flint into a fountain of waters. (Psalms 114:7-8)

...all who make payment from the lakes of the soul. (Isaiah 19:10)

In an opposite sense from the following:

I will cut off from Babylon the name and remnant..., and I will make it into a possession of the bird of prey, and into lakes of water. (Isaiah 14:22-23)

Death and hell were cast into the lake of fire. (Revelation 20:14)

If anyone was not found written in the Book of Life, he was cast into the lake of fire. (Revelation 20:15)

...their part in the lake of fire burning with brimstone, which is the second death. (Revelation 21:8)

599. So as to even make fire come down from heaven to earth in the sight of men. This symbolizes assertions that their falsities are truths from heaven, that people who accept them are saved, and that people who do not accept them perish.

This is the symbolism of these words, because the greatest signs were produced by fire from heaven. It was therefore a common expression of assurance among the ancients that, when bearing witness to some truth, they could rain down fire from heaven to attest to it. And this symbolically meant that they could attest to it to such a degree of certainty.

That fire from heaven also did attest to truth is apparent from the fact that the burnt offering offered by Aaron was consumed by fire from heaven (Leviticus 9:24). So, too, the burnt offering offered by Elijah (1 Kings 18:38).

[2] In an opposite sense, fire from heaven was a sign attesting that the people were caught up in evils and the accompanying falsities, and so would perish. But that fire was a consuming fire, such as the fire from heaven that consumed Aaron's two sons in Leviticus 10:1-6; that consumed the two hundred and fifty men in Numbers 26:10; that consumed the outskirts of the camp in Numbers 11:1-3; and that twice consumed the fifty men sent by the king to Elisha in 2 Kings 1:10, 12. Such also was the fire and brimstone rained down from heaven on Sodom in Genesis 19:24, 25; and the fire from heaven that consumed the people who surrounded the camp of the saints and the beloved city in Revelation 20:9. Once, when incensed at some impenitent people, the disciples said to Jesus, "Do You want us to command fire to come down from heaven and consume them?" (Luke 9:54).

We cite these instances to show that fire from heaven symbolizes an attestation, indeed an assurance, that truth is true, and in an opposite sense, that falsity is true, as in the present instance.

Fire also symbolizes a heavenly love and so a zeal for truth, and in an opposite sense a hellish love and so a zeal for falsity (nos. 468, 494).
