Charles Spurgeon Commentary Revelation 21:10-13

"And he carried me away in the Spirit to a mountain great and high, and showed me the holy city Jerusalem, coming down out of heaven from God, having the glory of God: her light was like unto a stone most precious, as it were a jasper stone, clear as crystal: having a wall great and high; having twelve gates, and at the gates twelve angels; and names written thereon, which are [the names] of the twelve tribes of the children of Israel: on the east were three gates; and on the north three gates; and on the south three gates; and on the west three gates." — Revelation 21:10-13 (ASV)

And he carried me away in the Spirit to a great and high mountain and shewed me that great city, the holy Jerusalem, descending out of heaven from God, having the glory of God: and her light was like unto a stone most precious, even like a jasper stone, clear as crystal; and had a wall great and high, and had twelve gates, and at the gates twelve angels, and names written thereon, which are the names of the twelve tribes of the children of Israel: on the east three gates; on the north three gates; on the south three gates; and on the west three gates.

God's glorified Church lies open to all quarters of the infinitude of space; it is no prison-house of souls that dare not go beyond its borders, but a many-gated city, so that the blessed spirits there can fly wherever they will.
