Revelation 21:18 (KJV)

What does Revelation 21:18 mean?

Revelation 21:18 describes the wall of the New Jerusalem as being made of jasper, while the city itself is made of pure gold that is as clear as glass. This verse uses imagery of precious materials to show the extraordinary beauty and purity of the heavenly city.

John, the author of Revelation, is sharing a vision given to him while exiled on the island of Patmos. In this part of his vision, he is describing the appearance of the New Jerusalem, a symbolic city representing God’s renewed creation. The focus on jasper and transparent gold highlights the city’s unmatched value, clarity, and holiness.

The Greek behind Revelation 21:18

• ἰάσπις (iaspis, "jasper"): This word refers to a precious stone, often understood as a clear or greenish gem in ancient times. Its use here emphasizes the brilliance and worth of the city’s wall.
• καθαρὸν (katharon, "pure"): This word describes the gold as completely pure, without any impurity. The Greek here stresses not just value but absolute perfection and cleanliness.
• ὑάλινος (hyalinos, "glass"): This word means "glassy" or "like glass," and in the context of ancient Greek, it suggests something both transparent and beautiful. The gold is not just valuable but also so pure it is see-through, which would have been an astonishing image for ancient readers.

Why Revelation 21:18 matters

• This verse clarifies that the New Jerusalem is not just valuable but also perfectly pure and transparent, which points to a deeper spiritual reality of openness and holiness in God’s presence.
• The description connects to the wider passage by continuing the detailed vision of the city’s construction, helping readers picture the overwhelming glory and perfection of the place God prepares.
• The use of jasper and transparent gold challenges assumptions about earthly wealth, showing that in God’s city, even the most precious materials are used as basic building blocks, shifting the focus from material value to spiritual significance.
