Revelation 21:9-14 NKJV
Then one of the seven angels who had the seven bowls filled with the seven last plagues came to me and talked with me, saying, “Come, I will show you the bride, the Lamb’s wife.” And he carried me away in the Spirit to a great and high mountain, and showed me the great city, the holy Jerusalem, descending out of heaven from God, having the glory of God. Her light was like a most precious stone, like a jasper stone, clear as crystal. Also she had a great and high wall with twelve gates, and twelve angels at the gates, and names written on them, which are the names of the twelve tribes of the children of Israel: three gates on the east, three gates on the north, three gates on the south, and three gates on the west.
Now the wall of the city had twelve foundations, and on them were the names of the twelve apostles of the Lamb.
