Revelation 21:10-13

10And 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,

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

12Also 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:

13three gates on the east, three gates on the north, three gates on the south, and three gates on the west.
