'Wealth and treasures' signify the knowledges of truth and good from the Word, and in the opposite sense, false knowledge from self derived intelligence.

(Referencat: Apocalypse Explained 654)

4508. 'And all their wealth' means all factual knowledge which they had acquired for themselves. This is clear from the meaning of 'wealth' as factual knowledge, as may be seen from many places in the Word. For spiritual wealth, and so the wealth that is meant in the spiritual sense, is nothing other. Insofar as such wealth consists in actual knowing, it is factual knowledge. In the Lord's kingdom, and therefore in the Church, that knowledge exists in place of material wealth, as will be substantiated in the Lord's Divine mercy from other places in the Word.
