Apostelgeschichte 7:42
42
Aber Gott wandte sich und gab sie dahin, daß sie dieneten des Himmels Heer; wie denn geschrieben stehet in dem Buch des Propheten: Habt ihr vom Hause Israel die vierzig Jahre in der Wüste mir auch je Opfer und Vieh geopfert?
Dark
Darkness" is a state without light. "Light" is truth from the Lord, so "darkness" represents a state where truth is lacking. Here's a cogent passage from Arcana Coelestia: "The person who has yet to be regenerated is called 'a void and an empty earth', and also 'ground', in which no good or truth at all has been sown - 'void' where there is no good, and 'empty' where there is no truth. Consequently there is 'thick darkness', or stupidity and lack of knowledge about anything that has to do with faith in the Lord and so anything that has to do with spiritual and celestial life. (Arcana Coelestia 17)
