Revelation 21:9-14

And there came one of the seven angels who had the seven bowls, who were laden with the seven last plagues; and he spake with me, saying, Come hither, I will show thee the bride, the wife of the Lamb. And he carried me away in the Spirit to a mountain great and high, and showed me the holy city Jerusalem, coming down out of heaven from God, having the glory of God: her light was like unto a stone most precious, as it were a jasper stone, clear as crystal: having 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: on the east were three gates; and on the north three gates; and on the south three gates; and on the west three gates. And the wall of the city had twelve foundations, and on them twelve names of the twelve apostles of the Lamb.
