Revelation 21: 9-14
21:9 And one of the seven Angels, those holding the bowls filled with the seven last afflictions, approached and spoke with me, saying: “Come, and I will show you the bride, the wife of the Lamb.”
21:10 And he took me up in spirit to a great and high mountain. And he showed me the Holy City Jerusalem, descending out of heaven from God,
21:11 having the glory of God. And its light was like that of a precious stone, even like that of the jasper stone or like crystal.
21:12 And it had a wall, great and high, having twelve gates. And at the gates were twelve Angels. And names were written upon them, which are the names of the twelve tribes of the sons of Israel.
21:13 On the East were three gates, and on the North were three gates, and on the South were three gates, and on the West were three gates.
21:14 And the wall of the City had twelve foundations. And upon them were the twelve names of the twelve Apostles of the Lamb.
