Revelation 21:10-13, 21-25
10 And he carried me away in the spirit to a great and high mountain, and shewed me that great city, the holy Jerusalem, descending out of heaven from God,
11 Having the glory of God: and her light was like unto a stone most precious, even like a jasper stone, clear as crystal;
12 And had a wall great and high, and had twelve gates, and at the gates twelve angels, and names written thereon, which are the names of the twelve tribes of the children of Israel:
13 On the east three gates; on the north three gates; on the south three gates; and on the west three gates.
21 And the twelve gates were twelve pearls; every several gate was of one pearl: and the street of the city was pure gold, as it were transparent glass.
22 And I saw no temple therein: for the Lord God Almighty and the Lamb are the temple of it.
23 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.
24 And the nations of them which are saved shall walk in the light of it: and the kings of the earth do bring their glory and honour into it.
25 And the gates of it shall not be shut at all by day: for there shall be no night there. shall not be shut at all by day: for there shall be no night there.
