Revelation 21:10-13

10And 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,

11Having the glory of God: and her light was like unto a stone most precious, even like a jasper stone, clear as crystal;

12And 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:

13On the east three gates; on the north three gates; on the south three gates; and on the west three gates.
