Revelation 21:23-26

The city has no need of the sun or the moon to shine on it, because the glory of God shines on it, and the Lamb is its lamp. The peoples of the world will walk by its light, and the kings of the earth will bring their wealth into it. The gates of the city will stand open all day; they will never be closed, because there will be no night there. The greatness and the wealth of the nations will be brought into the city.
