LOL- I'm too lazy to type anything- but here's a scan of 'The Dead Sea Scrolls' (Wise Abegg & Cook) pg. 180:
THE DEAD SEA SCROLLS
12. A VISION OF THE NEW JERUSALEM
1Q32, 2Q24, 4Q554-555, 5Q15, 11Q18
In the year 586 B.C.E., the armies of Nebuchadnezzar, king of Babylon, destroyed the Temple of the Lord that King Solomon had built in Jerusalem. Some of the best religious thinkers in ancient Israel, such as the prophet Jeremiah, saw in this event the welcome judgment of God on a nation that had placed too much reliance on external worship and not enough on the religion of the heart. Others equally pious, such as Ezekiel, agreed, but longed for the day when the God of Israel would restore to his people all that had been lost, giving them a new temple and temple city. Ezekiel himself contributed to this longing with a vision of a new temple and a new Jerusalem (Ezek. 40-48), but he was not alone. The book of Isaiah speaks of a new Jerusalem encrusted with jewels (54:11-12), and the book of Tobit speaks of a time when "Jerusalem and the temple of God will be rebuilt in splendor, just as the prophets have said" (14:6-7).
The new Temple built after the Israelites returned from exile in the fifth century B.C.E. was only a modest substitute for these dreams, and those who remembered the first Temple wept when they saw the foundation laid for the new one (Ezra 3:12). There were still dreams of another, greater, temple. In the first century B.C.E., Herod the Great doubtless depended on widespread fascination with such a dream to provide popular support for his building programs within Jerusalem, including a new, magnificent Temple.
The Qumran texts testify to this continuing fascination of the idea of a new Jerusalem with two examples: text 131, The Temple Scroll, and the present text. A Vision of the New Jerusalem, reconstructed from several scrolls, is a detailed description of a Jerusalem-to-be given by an angel to an unknown recipient, quite in the manner of Ezekiel's vision, but differing in many details. No description of the temple itself survives in the fragments, but the temple is mentioned several times.
The dimensions of the visionary city and buildings are too large to be realistic. The city, for example, measures 140 stades on the east and the west, and 100 stades on the north and south. In modern terms these dimensions would be 18.67 miles by 13.33 miles (the stade being 2/15 of a mile). This new Jerusalem would have been larger than any ancient city and could only have been built by divine intervention, like the even larger city beheld by a later visionary in the New Testament book of Revelation (21:9-27).
So there was nothing unusual about the new Jerusalem in Revelation- it seems to have been a common desired vision in the 1st century.
