26. Verse 8 And there was evening, and there was morning, a second day.

What 'evening', 'morning', and 'day' mean, has been shown already at verse 5.

In Genesis 1:16, this signifies goods and truths, or, in the opposite sense, evils and falsities. (Arcana Coelestia 1808)

In Matthew 24:29, this signifies knowledge of faith which falls from heaven. (Arcana Coelestia 32, 1984[3])

'Stars' signify the knowledge of truth and good. 'Stars' are frequently mentioned in the Word, and always signify goods and truths, but in an opposite sense, evils and falsities. In the same way, they signify angels, or societies of angels, in the opposite sense, evil spirits and their bands. When they signify angels, or societies of angels, then they are fixed stars, but when they signify evil spirits and their fellowships, then they are wandering stars. 'The seven stars' in Revelation 1, denote the knowledge of everything pertaining to good and truth, and so every variety of good and truth.
