Revelation 21:10-14

And he 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,

having the glory of God. Her brilliance was like a very valuable stone, like a stone of crystal-clear jasper.

It had a great and high wall, with twelve gates, and at the gates twelve angels; and names were written on the gates, which are the names of the twelve tribes of the sons of Israel.

There were three gates on the east, three gates on the north, three gates on the south, and three gates on the west.

And the wall of the city had twelve foundation stones, and on them were the twelve names of the twelve apostles of the Lamb.
