Revelation 21:12

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

11having the glory of God. Her light was like a most precious stone, like a jasper stone, clear as crystal;

12having a great and high wall with twelve gates, and at the gates twelve angels, and names written on them, 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.

14The wall of the city had twelve foundations, and on them twelve names of the twelve Apostles of the Lamb.
