9 Then came one of the seven angels who had the seven bowls full of the seven last plagues and spoke to me, saying, “Come, I will show you the Bride, the wife of the Lamb.” (Re 15:1; Re 17:1; Re 21:2)10 And he carried me away in the Spirit to a great, high mountain, and showed me the holy city Jerusalem coming down out of heaven from God, (Ps 87:1; Eze 40:2; Eze 43:5; Re 17:3)11 having the glory of God, its radiance like a most rare jewel, like a jasper, clear as crystal. (Ps 84:11; Eze 43:2; Eze 43:4; Mt 5:14; Php 2:15; Re 4:3; Re 4:6; Re 21:23; Re 22:5)12 It had a great, high wall, with twelve gates, and at the gates twelve angels, and on the gates the names of the twelve tribes of the sons of Israel were inscribed— (Eze 48:31)13 on the east three gates, on the north three gates, on the south three gates, and on the west three gates.14 And the wall of the city had twelve foundations, and on them were the twelve names of the twelve apostles of the Lamb. (Mt 16:18; 1Co 3:11; Eph 2:20; Heb 11:10)15 And the one who spoke with me had a measuring rod of gold to measure the city and its gates and walls. (Re 11:1)16 The city lies foursquare, its length the same as its width. And he measured the city with his rod, 12,000 stadia.
1. About 1,380 miles; a stadion was about 607 feet or 185 meters
 Its length and width and height are equal.17 He also measured its wall, 144 cubits
1. A cubit was about 18 inches or 45 centimeters
 by human measurement, which is also an angel’s measurement. (De 3:11; Re 13:18; Re 21:9)18 The wall was built of jasper, while the city was pure gold, like clear glass. (Re 21:11)19 The foundations of the wall of the city were adorned with every kind of jewel. The first was jasper, the second sapphire, the third agate, the fourth emerald, (Isa 54:11)20 the fifth onyx, the sixth carnelian, the seventh chrysolite, the eighth beryl, the ninth topaz, the tenth chrysoprase, the eleventh jacinth, the twelfth amethyst.21 And the twelve gates were twelve pearls, each of the gates made of a single pearl, and the street of the city was pure gold, like transparent glass. (Re 22:2)22 And I saw no temple in the city, for its temple is the Lord God the Almighty and the Lamb. (Joh 4:23)23 And the city has no need of sun or moon to shine on it, for the glory of God gives it light, and its lamp is the Lamb. (Isa 60:19; Re 21:11; Re 21:25; Re 22:5)24 By its light will the nations walk, and the kings of the earth will bring their glory into it, (Isa 60:3; Isa 60:5; Isa 60:16; Re 21:26; Re 22:2)25 and its gates will never be shut by day—and there will be no night there. (Isa 60:11; Re 21:23)26 They will bring into it the glory and the honor of the nations.27 But nothing unclean will ever enter it, nor anyone who does what is detestable or false, but only those who are written in the Lamb’s book of life. (Isa 35:8; Isa 52:1; Eze 44:9; Joe 3:17; Zec 14:21; Re 3:5; Re 22:14)
