Isaiah 60:19,20

Comp. Revelation 21:23: "And the city had no need of the sun, neither of the moon, to shine in it; for the glory of God did lighten it, and the Lamb is the light thereof"; and Isaiah 22:5. It is not implied that the sun and moon shall cease to exist; all that is said is that the new Jerusalem shall not be dependent on these natural luminaries. But that an actual physical illumination of the city by the glory of Jehovah is contemplated by the prophet can hardly be doubted. The basis of the conception is perhaps to be found in Ezekiel 43:2.
