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.
Gathered together, waters
In Exodus 15:8, this signifies falsities gathered together. Waters normally signify truths, but in this case, where they were blocking the escape of the Children of Israel from slavery and signify the opposite: falsities.
