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.
Ezekiel 1:26-28
26
Above the expanse that was over their heads was the likeness of a throne, as the appearance of a sapphire stone; and on the likeness of the throne was a likeness as the appearance of a man on it above.
27
I saw as it were glowing metal, as the appearance of fire within it all around, from the appearance of his waist and upward; and from the appearance of his waist and downward I saw as it were the appearance of fire, and there was brightness around him.
28
As the appearance of the rainbow that is in the cloud in the day of rain, so was the appearance of the brightness all around. This was the appearance of the likeness of the glory of Yahweh. When I saw it, I fell on my face, and I heard a voice of one that spoke.
