'Light' in the Bible

The fourth angel blew his trumpet, and a third of the sun was struck, a third of the moon, and a third of the stars, so that a third of them were darkened. A third of the day was without light, and the night as well.

the light of a lampwill never shine in you again;and the voice of a groom and bridewill never be heard in you again.All this will happenbecause your merchantswere the nobility of the earth,because all the nations were deceivedby your sorcery,

The nations will walk in its light, and the kings of the earth will bring their glory into it.

Night will no longer exist, and people will not need lamplight or sunlight, because the Lord God will give them light. And they will reign forever and ever.
