788. 18:19 "And they put dust on their heads and cried out, weeping and mourning, and saying, 'Woe, woe, that great city!'" This symbolizes their interior and exterior grief and mourning, which is a lamentation that so eminent a religion was completely destroyed and condemned.

Putting dust on their heads symbolizes their interior and exterior grief and mourning over the destruction and damnation, as we will show below. To cry out, weeping and mourning, symbolizes their exterior grief and mourning - to weep symbolizing a mourning of the soul, and to grieve a grief of the heart. "Woe, woe, that great city!" symbolizes a grievous lamentation over the destruction and damnation. That "woe" symbolizes a lamentation over a calamity, misfortune, or damnation, and that "woe, woe," therefore symbolizes a grievous lamentation, may be seen in nos. 416, 769, 785; and that the city symbolizes the Roman Catholic religion may be seen in no. 785 and elsewhere.

That putting dust on the head symbolizes an interior grief and mourning over a destruction and damnation is clear from the following passages:

They will cry bitterly and cast dust on their heads; they will roll about in ashes. (Ezekiel 27:30)

(The daughters) of Zion sit on the ground...; they have cast dust on their heads... (Lamentations 2:10)

(Job's friends) rent their tunics and sprinkled dust upon their heads... (Job 2:12)

Come down and sit in the dust, O virgin daughter of Babylon; sit on the ground without a throne... (Isaiah 47:1)

And so on elsewhere.

The people put dust on their heads when they grieved deeply, because dust symbolized something damned, as is apparent from Genesis 3:14, Matthew 10:14, Mark 6:11, Luke 10:10-12, and dust on the head represented the people's acknowledgment that of themselves they were damned, and thus their repentance, as in Matthew 11:21, Luke 10:13.

Dust symbolizes something damned because the land over the hells in the spiritual world consists of nothing but dust, without grass or plants.

Stones in the Bible in general represent truths, or things we know concerning the Lord and what He wants from us and for us in life. This is why the people of Israel built altars of stone, and is also why stoning was a principal form of capital punishment (using truth to destroy falsity, or in the negative sense using falsity to destroy truth). It is also why precious stones are described in such detail on Aaron's breastplate and ephod, and also in the New Jerusalem in Revelation; precious stones represent true ideas directly from the Lord with the various colors showing various forms of love. Stones are not alone in representing truth, of course -- it sometimes seems that almost everything in the Bible represents either true ideas or desires for good. But that makes sense, since our thoughts and our desires together are everything we are in life, and the interplay between them is what life is all about. The many ways they are represented in the Bible reflect the incredible variety in our feelings and thoughts, though we can only distantly understand how those representations work. In the case of stones, in their weight, strength and permanence they tend to represent true ideas that come from a desire for good, the understanding we can have if we are truly good and loving -- and in the highest sense the exalted ideas that come from the Lord's love. Those ideas are ones that are not easily moved or changed, and make wonderful foundations for the things we want to build in our spiritual lives.
