Revelation 21:16 (KJV)

What does Revelation 21:16 mean?

Revelation 21:16 describes the measurements of the New Jerusalem, saying the city is perfectly square, with its length, width, and height all equal—measured at twelve thousand furlongs each. This verse emphasizes the city’s symmetry and vast size as part of John’s vision of the new creation.

The apostle John is describing what he sees in his vision, as an angel measures the heavenly city with a reed. The focus on equal dimensions highlights the city’s perfection and completeness. The mention of “twelve thousand furlongs” uses a large, symbolic number, showing the city’s immense scale and perhaps connecting to the idea of fullness or completeness found throughout Revelation.

The Greek behind Revelation 21:16

• τετράγωνος (tetragōnos, G5068): This word means “foursquare” or “perfectly square,” stressing the city’s equal proportions on all sides, which would have been seen as a sign of perfection and order.
• μέτρον (metron, G3354, “measured”): The act of measuring with a reed (κάλαμος, kalamos, G2563) shows careful attention to the city’s exact size, underlining its intentional design.
• δώδεκα χιλιάδες σταδίων (dōdeka chiliades stadiōn, G1427, G5505, G4712): “Twelve thousand furlongs” is a huge distance, often understood as symbolic of completeness and the inclusion of all God’s people, since twelve is a significant number in biblical imagery.
• ἴσα (isa, G2470): This word means “equal,” and its use here stresses that the city’s length, breadth, and height are exactly the same, which is unusual for a city and draws attention to its unique, heavenly nature.

Why Revelation 21:16 matters

• The verse clears up any idea that the New Jerusalem is an ordinary city; its perfect cube shape and immense size set it apart as something entirely new and divine.
• The detailed measurements connect to Old Testament imagery of the Holy of Holies, which was also a perfect cube, hinting that the whole city is now a holy place where God dwells with people.
• This verse helps readers see that the vision is not just about physical size, but about completeness, perfection, and the fulfillment of God’s promises.
