12 She had a wall majestic and high with twelve gates. At each gate stood an Angel, and on the gates were inscribed the names of the Twelve Tribes of the sons of Israel: 13 three gates on the east, three gates on the north, three gates on the south, three gates on the west. 14 The wall was set on twelve foundations, the names of the Twelve Apostles of the Lamb inscribed on them. 15 The Angel speaking with me had a gold measuring stick to measure the City, its gates, and its wall. 16 The City was laid out in a perfect square. He measured the City with the measuring stick: twelve thousand stadia, its length, width, and height all equal. 17 Using the standard measure, the Angel measured the thickness of its wall: 144 cubits. 18 The wall was jasper, the color of Glory, and the City was pure gold, translucent as glass. 19 The foundations of the City walls were garnished with every precious gem imaginable: the first foundation jasper, the second sapphire, the third agate, the fourth emerald, 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.

Commentary on Revelation 21:9-21
(Read Revelation 21:9-21)
God has various employments for his holy angels. Sometimes they sound the trumpet of Divine Providence, and warn a careless world; sometimes they discover things of a heavenly nature of the heirs of salvation. Those who would have clear views of heaven, must get as near to heaven as they can, on the mount of meditation and faith. The subject of the vision is the church of God in a perfect, triumphant state, shining in its lustre; glorious in relation to Christ; which shows that the happiness of heaven consists in intercourse with God, and in conformity to him. The change of emblems from a bride to a city, shows that we are only to take general ideas from this description. The wall is for security. Heaven is a safe state; those who are there, are separated and secured from all evils and enemies. This city is vast; here is room for all the people of God. The foundation of the wall; the promise and power of God, and the purchase of Christ, are the strong foundations of the safety and happiness of the church. These foundations are set forth by twelve sorts of precious stones, denoting the variety and excellence of the doctrines of the gospel, or of the graces of the Holy Spirit, or the personal excellences of the Lord Jesus Christ. Heaven has gates; there is a free admission to all that are sanctified; they shall not find themselves shut out. These gates were all of pearls. Christ is the Pearl of great price, and he is our Way to God. The street of the city was pure gold, like transparent glass. The saints in heaven tread gold under foot. The saints are there at rest, yet it is not a state of sleep and idleness; they have communion, not only with God, but with one another. All these glories but faintly represent heaven.
