Arcana Coelestia #9654
9654. 'You shall make six boards' means where good from the Lord's Divine Human exists in its fullness. This is clear from the meaning of 'six' as all things in their entirety, dealt with in 7973, thus also in fullness; and from the meaning of 'the boards' of the dwelling-place as good from the Lord's Divine Human, supporting heaven, dealt with in 9644.
Arcana Coelestia #7083
7083. Heat and light in the natural world emanate from the sun in the world, whereas spiritual heat and spiritual light, or love and faith, emanate from the sun in heaven. The Lord is the sun in heaven, and the heat which comes from Him as the Sun is love, while the light which comes from Him as the Sun is faith. The fact that the Lord is light is clear in John,
Jesus said, I am the light of the world. He who follows Me will not walk in darkness but will have the light of life. John 8:12.
And the fact that the Lord is a sun is clear in Matthew,
When Jesus was transfigured His face shone like the sun, and His clothes became [white] as the light. Matthew 17:1.
