'Noah,' as in Genesis 5:29, signifies the ancient church, or the parent of the three churches after the flood.

(参照: Arcana Coelestia 528, 529)

528. Verse 29 And he called his name Noah, saying, He will comfort us from our work and from the toil of our hands that comes from the ground which Jehovah has cursed.

'Noah' means the Ancient Church. 'Comforting us from our work and from the toil of our hands that comes from the ground which Jehovah has cursed' means the doctrine by which what had been corrupted would be restored.
