Arcana Coelestia #21
21. Verses 4-5 And God saw that the light was good; and God made a distinction between the light and the darkness. And God called the light Day, and the darkness He called Night.
The light is called good, because it comes from the Lord, who is good itself. 'The darkness' is those things which were there prior to the person's new conception and birth. They were seen as light, because evil was seen as good, and falsity as truth. But in reality they are darkness and things proper to that person which are lingering on. All things that are the Lord's, being things of light, are compared to the day, and all that are man's own, being those of thick darkness, are compared to the night, as is done many times in the Word.
Arcana Coelestia #9342
9342. 'For I will give the inhabitants of the land into your hand' means dominion over evils. This is clear from the meaning of 'giving into the hand' as overcoming and having dominion over; and from the meaning of 'the inhabitants of the land' as the Church's evils. Forms of good are meant by 'inhabitants', 2268, 2451, 2712, 3613, and therefore evils in the contrary sense; for the nations of the land of Canaan meant evils and falsities molesting and destroying the Church's forms of good and its truths, 9327.
