Revelation 21:23-25

And the city has no need of the sun nor of the moon to give light to it, for the glory (splendor, radiance) of God has illumined it, and the Lamb is its lamp and light. [Is 24:23; 60:19, 20] The nations [the redeemed people from the earth] will walk by its light, and the kings of the earth will bring into it their glory. [Is 60:1-5] By day (for there will be no night there) its gates will never be closed [in fear of evil]; [Is 60:11]
