Revelation21
22I saw no temple in it, for the Lord God the Almighty and the Lamb are its temple. 23And the city has no need of the sun or of the moon to shine on it, for the glory of God has illuminated it, and its lamp is the Lamb.
Rev 22
5And there will no longer be any night; and they will not have need of the light of a lamp nor the light of the sun, because the Lord God will illuminate them; and they will reign forever and ever.
