Arcana Coelestia #4312
4312. In the internal historical sense 'the sun rose on him' means when they entered into representations. This is clear from the meaning - in this sense, in which the subject is the descendants of Jacob - of 'the rising of the sun' as when they entered into representations. 'The coming up of the dawn' meant the state before they entered into representations, 4289. The sun is also said to rise with anyone who is becoming the Church, and so is said to do so with anyone who is becoming a representative of the Church.
Exodus 19:11-13
11
and be ready against the third day; for on the third day Yahweh will come down in the sight of all the people on Mount Sinai.
12
You shall set bounds to the people all around, saying, 'Be careful that you don't go up onto the mountain, or touch its border. Whoever touches the mountain shall be surely put to death.
13
No hand shall touch him, but he shall surely be stoned or shot through; whether it is animal or man, he shall not live.' When the trumpet sounds long, they shall come up to the mountain."
