### Core Meaning & Semantic Range
The Greek word **hyálinos**, represented by `{{G5193}}`, describes something as **glassy** or **transparent**. Derived from ὕαλος (glass), its meaning is focused on this see-through quality. It appears only **3 times** across **2 unique verses**, with all occurrences found in the book of Revelation.
### Biblical Occurrences & Contextual Analysis
In the biblical narrative, `{{G5193}}` is used exclusively to describe a magnificent feature within John's heavenly vision. It first appears as a "sea of **glass**" located before the throne of God, noted to be "like unto crystal" [[Revelation 4:6]]. This image is seen again later, but this time the "sea of **glass**" is "mingled with fire" [[Revelation 15:2]]. In this second instance, it is the place where those who have gained victory over the beast and his image stand.
### Related Words & Concepts
Several related words help clarify the imagery associated with **hyálinos**:
* `{{G2281}}` **thálassa** (the sea): This word is directly modified by **hyálinos** in both of its occurrences, forming the specific phrase "a **sea** of glass" ([[Revelation 4:6]], [[Revelation 15:2]]).
* `{{G2930}}` **krýstallos** (crystal): This is used to describe the appearance of the glassy sea, emphasizing its perfect clarity and brilliance [[Revelation 4:6]].
* `{{G4442}}` **pŷr** (fire): This element is described as being "mingled" with the sea of glass, connecting it to themes of judgment and purification where the victorious saints stand [[Revelation 15:2]].
### Theological Significance
The theological weight of `{{G5193}}` is concentrated in its symbolic role within the heavenly throne room.
* **Divine Majesty and Purity:** Positioned before God's throne, the "sea of **glass**" conveys a sense of perfect calm, stability, and purity in the divine presence. Its comparison to **crystal** reinforces this image of unblemished perfection [[Revelation 4:6]].
* **Triumph and Purification:** The sea is later seen "mingled with **fire**" [[Revelation 15:2]], the place where victorious saints stand. This imagery suggests that the peace and stability of heaven are reached after passing through fiery trials.
* **Sovereignty over Chaos:** In scripture, the **sea** can represent turmoil and distress [[Luke 21:25]]. A sea rendered as solid, transparent **glass** symbolizes the absolute peace and order that exists under God's sovereign rule.
### Summary
In summary, `{{G5193}}` is a highly specific descriptive term used in Revelation to articulate a profound vision. It defines the sea before God's throne, transforming an image of chaos into one of perfect tranquility and transparency. Whether depicted as pure **crystal** or as mingled with **fire**, **hyálinos** illustrates divine majesty, the purity of God's realm, and the firm foundation upon which triumphant believers stand.
