Revelation 21:5-27

And the one who was seated on the throne said, "See, I am making all
things new."  Also he said, "Write this, for these words are trustworthy
and true."  Then he said to me, "It is done!  I am the Alpha and the
Omega, the beginning and the end.  To the thirsty I will give water as a
gift from the spring of the water of life.  Those who conquer will inherit
these things, and I will be their God and they will be my children.  But
as for the cowardly, the faithless, the polluted, the murderers, the
fornicators, the sorcerers, the idolaters, and all liars, their place will
be in the lake that burns with fire and sulfur, which is the second
death."

Then one of the seven angels who had the seven bowls full of the seven
last plagues came and said to me, "Come, I will show you the bride, the
wife of the Lamb."  And in the spirit he carried me away to a great, high
mountain and showed me the holy city Jerusalem coming down out of heaven
from God.  It has the glory of God and a radiance like a very rare jewel,
like jasper, clear as crystal.  It has a great, high wall with twelve
gates, and at the gates twelve angels, and on the gates are inscribed the
names of the twelve tribes of the Israelites; on the east three gates, on
the north three gates, on the south three gates, and on the west three
gates.  And the wall of the city has twelve foundations, and on them are
the twelve names of the twelve apostles of the Lamb.

The angel who talked to me had a measuring rod of gold to measure the city
and its gates and walls.  The city lies foursquare, its length the same as
its width; and he measured the city with his rod, fifteen hundred miles;
its length and width and height are equal.  He also measured its wall, one
hundred forty-four cubits by human measurement, which the angel was using.
The wall is built of jasper, while the city is pure gold, clear as glass.
The foundations of the wall of the city are adorned with every jewel; the
first was jasper, the second sapphire, the third agate, the fourth
emerald, the fifth onyx, the sixth carnelian, the seventh chrysolite, the
eighth beryl, the ninth topaz, the tenth chrysoprase, the eleventh
jacinth, the twelfth amethyst.  And the twelve gates are twelve pearls,
each of the gates is a single pearl, and the street of the city is pure
gold, transparent as glass.

I saw no temple in the city, for its temple is the Lord God the Almighty
and the Lamb.  And the city has no need of sun or moon to shine on it, for
the glory of God is its light, and its lamp is the Lamb.  The nations will
walk by its light, and the kings of the earth will bring their glory into
it.  Its gates will never be shut by day and there will be no night there.
People will bring into it the glory and the honor of the nations.  But
nothing unclean will enter it, nor anyone who practices abomination or
falsehood, but only those who are written in the Lamb's book of life.
