Arcana Coelestia # 1041
1041. 'Into the generations of an age' means all unceasingly who are being created anew. This is clear from the meaning of 'generations of an age'. 'Generations' means descendants of those going before as their parents. 'An age' is that which continues unceasingly. Here the subject is those things that have been regenerated and therefore 'the generations of an age' is used to mean those people who are unceasingly being regenerated in this way, that is, who are being created anew. In the internal sense the meaning of everything is determined by the subject under discussion.
Precious stones
In Exodus 28:17, this signifies the celestial love of good. (Arcana Coelestia 9862) 'Lazuli, agate, and amethyst' denote the spiritual love of good. 'Beryl, onyx, and jasper' denote spiritual love of truth and 'sardine' signifies divine truth. 'Ruby, topaz, and carbuncle' signify the celestial love of good because of their red, flaming color. 'A covering of precious stones,' as in Ezekiel 28:13, signifies the truths of intelligence. 'Precious stones,' in application to the Word, symbolize the Divine truth of the Word in its literal sense which the Divine truth in its spiritual sense shines through. 'Chrysoprasus, sapphire, and diamond' denote celestial love of truth. 'Emerald' signifies the sphere of divine love and wisdom.
