Arcana Coelestia #38
38. Verse 18 And to have dominion over the day and the night, and to make a distinction between the light and the darkness; and God saw that it was good.
'The day' is used to mean good, and 'the night' evil. Consequently goods are called 'the works of the day', whereas evils are called 'the works of the night'. 'The light' is used to mean truth, and 'the darkness' falsity, just as the Lord says,
Men preferred darkness rather than light; he who does the truth comes to the light. John 3:19-21.
Verse 19 And there was evening, and there was morning, a fourth day.
Exodus 2:23-25
23
It happened in the course of those many days, that the king of Egypt died, and the children of Israel sighed because of the bondage, and they cried, and their cry came up to God because of the bondage.
24
God heard their groaning, and God remembered his covenant with Abraham, with Isaac, and with Jacob.
25
God saw the children of Israel, and God was concerned about them.
