In Daniel 12:3, 'the learned,' or 'wise,' who 'shall shine as the stars,' are people who are in good.

(References: Arcana Coelestia 3820)

423. And the sun and the air were darkened because of the smoke of the pit. This symbolically means that therefore the light of truth became thick darkness.

The sun and the air here symbolize the light of truth, for the sun symbolizes love, and the light from it, Divine truth. Consequently, when we are told that the sun was darkened, and with it the air, it symbolically means that Divine truth became thick darkness. That this resulted from falsities accompanying lusts is symbolically meant by its being because of the smoke of the pit.
