Arcana Coelestia #60
60. Verse 31 And God saw everything that He had made, and behold, it was very good. And there was evening, and there was morning, a sixth day.
This verse says 'very good', whereas previous verses merely said 'good', for now the things of faith make one with those of love. A marriage has accordingly taken place between spiritual and celestial things.
Arcana Coelestia #533
533. Since nothing further is mentioned about Lamech apart from the fact that be beget sons and daughters, who are the conceptions and births of such a Church, there is no need to pause any longer over him. What these births, or sons and daughters, were, becomes clear from the Church, for the character of a Church determines that of its offspring. Both those Churches called Methuselah and Lamech breathed their last just before the flood.
