Revelation of John 21:23

Verse 23. And the city had no need of the sun, neither of the moon, to shine in it. This imagery seems to be derived from Isa 60:19-20. Isa 60:19 Isa 60:20. No language could give a more striking or beautiful representation of the heavenly state than that which is here employed.

For the glory of God did lighten it. By the visible splendour of his glory. Rev 21:11. That supplied the place of the sun and the moon.

And the Lamb is the light thereof. The Son of God; the Messiah. Rev 5:6; Isa 60:19.

(a) "sun" Rev 22:5, Isa 60:19,20 (b) "the light" Jn 1:4

Revelation of John 21:25

Verse 25. And the gates of it shall not be shut at all by day. It shall be constantly open, allowing free ingress and egress to all who reside there. The language is derived from Isa 60:11. Isa 60:11. Applied to the future state of the blessed, it would seem to mean, that while this will be their permanent abode, yet that the dwellers there will not be prisoners. The universe will be open to them. They will be permitted to go forth and visit every world, and survey the works of God in all parts of his dominions.

For there shall be no night there. It shall be all day; all unclouded splendour. When, therefore, it is said that the gates should not be "shut by day," it means that they would never be shut. When it is said that there would be no night there, it is, undoubtedly, to be taken as meaning that there would be no literal darkness, and nothing of which night is the emblem: no calamity, no sorrow, no bereavement, no darkened windows on account of the loss of friends and kindred. Compare Barnes on "Re 21:4".

(e) "for there shall be no night" Zech 14:7
