Isaiah 24:23 The moon will be abashed, the sun ashamed; for the LORD Almighty will reign on Mount Zion and in Jerusalem, and before its elders, gloriously.
Isaiah 60:19-20 "The sun will no more be your light by day, nor will the brightness of the moon shine on you, for the LORD will be your everlasting light, and your God will be your glory. Your sun will never set again and your moon will wane no more; the LORD will be your everlasting light, and your days of sorrow will end."
Revelation 22:5 There will be no more night. They will not need the light of a lamp or the light of the sun, for the Lord God will give them light. And they will reign for ever and ever.

and the Lamb is its lamp
Revelation 5:6 Then I saw a Lamb, looking as if it had been slain, standing in the center of the throne, encircled by the four living creatures and the elders. He had seven horns and seven eyes, which are the seven spirits of God sent out into all the earth.
