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 #4168
4168. 'These twenty years I have been with you' means the proprium. This is clear from the meaning of 'twenty' as the good present in remnants, 2280. But when the term remnants is used in reference to the Lord nothing else is meant than His proprium, 1906. 'Twenty years' means states of the proprium - 'years' meaning states, see 487, 488, 493, 893. In the highest sense the content of Jacob's words addressed to Laban refers to the proprium within the Natural which the Lord acquired to Himself by His own power, in particular to the various states of that proprium.
