Revelation 21:10-13

10And he carried me away in the Spirit to a mountain great and high, and shewed me the holy city Jerusalem, coming down out of heaven from God,

11having the glory of God: her light was like unto a stone most precious, as it were a jasper stone, clear as crystal:

12having a wall great and high; having 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 were three gates; and on the north three gates; and on the south three gates; and on the west three gates.
