Passage
On the east, three gates: and on the north, three gates: and on the south, three gates: and on the west, three gates.
On the east, three gates: and on the north, three gates: and on the south, three gates: and on the west, three gates.
Revelation 21:11 Having the glory of God, and the light thereof was like to a precious stone, as to the jasper stone even as crystal.
Revelation 21:12 And it had a wall great and high, having twelve gates, and in the gates twelve angels, and names written thereon, which are the names of the twelve tribes of the children of Israel.
Revelation 21:13 On the east, three gates: and on the north, three gates: and on the south, three gates: and on the west, three gates.
Revelation 21:14 And the wall of the city had twelve foundations: And in them, the twelve names of the twelve apostles of the Lamb,
Revelation 21:15 And he that spoke with me had a measure of a reed of gold, to measure the city and the gates thereof and the wall.
The verse centers on "east", "three", "gates", "north", and "south". It is saying that the verse draws attention to "east" and "three", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 12's "And it had a wall great and..." into verse 14's "And the wall of the city had...", so "east" and "three" belong inside that flow. In Revelation context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "east" and "three" with trust shaped by these words, not by a vague optimism outside the passage.
