Revelation 21:10-14

10And 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. 11It shone with the glory of God, and its brilliance was like that of a very precious jewel, like a jasper, clear as crystal. 12It had a great, high wall with twelve gates, and with twelve angels at the gates. On the gates were written the names of the twelve tribes of Israel. 13There were three gates on the east, three on the north, three on the south and three on the west.

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