{Shall be night no more} (
ux ouk estai eti). As in
 21:25 . {They need} (echousin chreian). Present active
indicative, "They have need," though A has hexousin (shall
have), future like estai. Here again there is repetition of
part of  21:23 , but for the purpose of showing the
delightsomeness of the New Jerusalem with no need of lamp or sun
(change to ph(9373) with h(886c)iou instead of ph(9374)os, "they have
no light of sun"). {Shall give them light} (ph(9374)isei). Future
active of ph(9374)iz(935c), while aorist eph(9374)isen in  21:23 . {They
shall reign} (asileusousin). Future active of asileu(935c).
Reign eternally in contrast with the limited millennial reign of
 20:4,6 . This glorious eternal reign with Christ occurs
repeatedly in the book ( 1:6  3:21  5:10 ) as in  Lu 22:30 .
Christ's Kingdom is spiritual ( Joh 18:36f. ). "The visions of
the Apocalypse are now ended; they have reached their climax in
the New Jerusalem" (Swete). Now John gives the parting utterances
of some of the speakers, and it is not always clear who is
speaking.
