Revelation 21:9-12

Then one of the seven angels who had the seven bowls full of the seven last plagues came and spoke with me, saying, “Come here, I will show you the bride, the wife of the Lamb.” 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 costly stone, as 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 them, which are the names of the twelve tribes of the sons of Israel.
