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 #7153
7153. 'And you shall deliver the tally of bricks' means the falsities which are to be introduced in abundance. This is clear from what has been stated above in 7116, where similar words occur. Such then are the [arcana] which these verses contain in the internal sense, things which perhaps seem to man to be of little importance and also unconnected with one another. Nevertheless each one is essential to the subject that is being dealt with; and all hang together in a very beautiful way. Angels perceive this to be true, for they see in the light of heaven the ways in which things follow one another and are linked together, and they see countless arcana formed out of interior truths, which gives those things a very beautiful and very lovely appearance. Man cannot do the same thing at all because interior truths are hidden from him. Nor therefore can he connect together the details contained in these verses; it seems to him as though they are disjointed, which is why, as has been stated, they seem to him to be of little importance.
