Revelation 21:10-21

And the angel carried me away by the Spirit to a very large and high mountain. He showed me the holy city, Jerusalem, coming down out of heaven from God. It was shining with the glory of God and was bright like a very expensive jewel, like a jasper, clear as crystal. The city had a great high wall with twelve gates with twelve angels at the gates, and on each gate was written the name of one of the twelve tribes of Israel. There were three gates on the east, three on the north, three on the south, and three on the west. The walls of the city were built on twelve foundation stones, and on the stones were written the names of the twelve apostles of the Lamb. The angel who talked with me had a measuring rod made of gold to measure the city, its gates, and its wall. The city was built in a square, and its length was equal to its width. The angel measured the city with the rod. The city was 1,500 miles long, 1,500 miles wide, and 1,500 miles high. The angel also measured the wall. It was 216 feet high, by human measurements, which the angel was using. The wall was made of jasper, and the city was made of pure gold, as pure as glass. The foundation stones of the city walls were decorated with every kind of jewel. The first foundation was jasper, the second was sapphire, the third was chalcedony, the fourth was emerald, the fifth was onyx, the sixth was carnelian, the seventh was chrysolite, the eighth was beryl, the ninth was topaz, the tenth was chrysoprase, the eleventh was jacinth, and the twelfth was amethyst. The twelve gates were twelve pearls, each gate having been made from a single pearl. And the street of the city was made of pure gold as clear as glass.
