Translation
The city
has no need for the sun
or the moon,
to shine in it,
for the glory of the LORD
enlightened it
and the LAMB is
its lamp.
Paraphrase
The collective people of God have no need for secondary sources of knowledge and insight, be they powerful sources
or weak sources, in order for them to have spiritual insight, for the glory of THE SUPREME RULER
gives them wisdom from the inside, and THE ONLY EFFICACIOUS SACRIFICE is their source of knowledge and wisdom.
