Revelation 21:23 - Clarke's commentary and critical notes on the Bible

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. No need of the sun - This is also one of the traditions of the ancient Jews, that "in the world to come the Israelites shall have no need of the sun by day, nor the moon by night." - Yalcut Rubeni, fol. 7, 3. God's light shines in this city, and in the Lamb that light is concentrated, and from him everywhere diffused.
