'Wealth' signifies scientific knowledge, as seen in several passages in the Word.

(Референце: Arcana Coelestia 4508)

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.
